Revised Critical Infrastructure Protection Reliability Standards

AGENCY: Federal Energy Regulatory Commission, Energy.

ACTION: Notice of proposed rulemaking.

-----------------------------------------------------------------------

SUMMARY: The Federal Energy Regulatory Commission (Commission) proposes 
to approve seven critical infrastructure protection (CIP) Reliability 
Standards: CIP-003-6 (Security Management Controls), CIP-004-6 
(Personnel and Training), CIP-006-6 (Physical Security of BES Cyber 
Systems), CIP-007-6 (Systems Security Management), CIP-009-6 (Recovery 
Plans for BES Cyber Systems), CIP-010-2 (Configuration Change 
Management and Vulnerability Assessments), and CIP-011-2 (Information 
Protection). The North American Electric Reliability Corporation (NERC) 
submitted the proposed Reliability Standards in response to the 
Commission's Order No. 791. The proposed Reliability Standards address 
the cyber security of the bulk electric system and improve upon the 
current Commission-approved CIP Reliability Standards. In addition, the 
Commission proposes to direct NERC to develop certain modifications to 
Reliability Standard CIP-006-6 and to develop requirements addressing 
supply chain management.

SUPPLEMENTARY INFORMATION: 
    1. Pursuant to section 215 of the Federal Power Act (FPA),\1\ the 
Commission proposes to approve seven critical infrastructure protection 
(CIP) Reliability Standards: CIP-003-6 (Security Management Controls), 
CIP-004-6 (Personnel and Training), CIP-006-6 (Physical Security of BES 
Cyber Systems), CIP-007-6 (Systems Security Management), CIP-009-6 
(Recovery Plans for BES Cyber Systems), CIP-010-2 (Configuration Change 
Management

and Vulnerability Assessments), and CIP-011-2 (Information Protection). 
The North American Electric Reliability Corporation, the Commission-
certified Electric Reliability Organization (ERO), submitted the 
proposed Reliability Standards in response to Order No. 791.\2\ The 
Commission also proposes to approve NERC's proposed implementation plan 
and violation risk factor and violation severity level assignments. In 
addition, we propose to approve NERC's proposed new or revised 
definitions for inclusion in the NERC Glossary of Terms Used in 
Reliability Standards (NERC Glossary). Further, the Commission proposes 
to approve the retirement of Reliability Standards CIP-003-5, CIP-004-
5.1, CIP-006-5, CIP-007-5, CIP-009-5, CIP-010-1, and CIP-011-1.

Standards, Order No. 791, 78 FR 72,755 (Dec. 3, 2013), 145 FERC ]

146 FERC ] 61,188 (2014).
---------------------------------------------------------------------------

    2. The proposed Reliability Standards are designed to mitigate the 
cybersecurity risks to bulk electric system facilities, systems, and 
equipment, which, if destroyed, degraded, or otherwise rendered 
unavailable as a result of a cybersecurity incident, would affect the 
reliable operation of the Bulk-Power System.\3\ As discussed below, we 
believe that the proposed CIP Reliability Standards are just and 
reasonable and address the directives in Order No. 791 by: (1) 
Eliminating the ``identify, assess, and correct'' language in 17 of the 
CIP version 5 Standard requirements; (2) providing enhanced security 
controls for Low Impact assets; (3) providing controls to address the 
risks posed by transient electronic devices (e.g., thumb drives and 
laptop computers); and (4) addressing in an equally effective and 
efficient manner the need for a NERC Glossary definition for the term 
``communication networks.'' Accordingly, we propose to approve the 
proposed CIP Reliability Standards because they improve the base-line 
cybersecurity posture of applicable entities compared to the current 
Commission-approved CIP Reliability Standards.
---------------------------------------------------------------------------

    \3\ See NERC Petition at 3.
---------------------------------------------------------------------------

    3. In addition, pursuant to FPA section 215(d)(5), the Commission 
proposes to direct NERC to develop certain modifications to Reliability 
Standard CIP-006-6. Specifically, while proposed CIP-006-6 would 
require protections for communication networks among a limited group of 
bulk electric system Control Centers, we propose to direct that NERC 
modify Reliability Standard CIP-006-6 to require protections for 
communication network components and data communicated between all bulk 
electric system Control Centers. In addition, we seek comment on the 
sufficiency of the security controls incorporated in the current CIP 
Reliability Standards regarding remote access used in relation to bulk 
electric system communications. Finally, as discussed in more detail 
below, we propose to direct NERC to develop requirements relating to 
supply chain management for industrial control system hardware, 
software, and services.

I. Background

A. Section 215 and Mandatory Reliability Standards

    4. Section 215 of the FPA requires a Commission-certified ERO to 
develop mandatory and enforceable Reliability Standards, subject to 
Commission review and approval. Reliability Standards may be enforced 
by the ERO, subject to Commission oversight, or by the Commission 
independently.\4\ Pursuant to section 215 of the FPA, the Commission 
established a process to select and certify an ERO,\5\ and subsequently 
certified NERC.\6\

---------------------------------------------------------------------------

B. Order No. 791

    5. On November 22, 2013, in Order No. 791, the Commission approved 
the CIP version 5 Standards (Reliability Standards CIP-002-5 through 
CIP- 009-5, and CIP-010-1 and CIP-011-1).\7\ The Commission determined 
that the CIP version 5 Standards represented an improvement over prior 
iterations of the CIP Reliability Standards because, inter alia, they 
included a revised BES Cyber Asset categorization methodology that 
incorporated mandatory protections for all High, Medium, and Low Impact 
BES Cyber Assets, and because several new security controls improved 
the security posture of responsible entities.\8\ In addition, pursuant 
to section 215(d)(5) of the FPA, the Commission directed NERC to: (1) 
Remove the ``identify, assess, and correct'' language in 17 of the CIP 
Standard requirements; (2) develop enhanced security controls for Low 
Impact assets; (3) develop controls to protect transient electronic 
devices (e.g., thumb drives and laptop computers); (4) create a NERC 
Glossary definition for the term ``communication networks,'' and 
develop new or modified Reliability Standards to protect the 
nonprogrammable components of communications networks.

    6. In addition, the Commission directed NERC to conduct a survey of 
Cyber Assets that are included or excluded under the new BES Cyber 
Asset definition and submit an informational filing within one year.\9\ 
Finally, the NOPR directed Commission staff to convene a technical 
conference to examine the technical issues concerning communication 
security, remote access, and the National Institute of Standards and 
Technology (NIST) Risk Management Framework.\10\

C. Informational Filing

    7. On February 3, 2015, NERC submitted an informational filing 
assessing the results of a survey conducted to identify the scope of 
assets subject to the definition of the term BES Cyber Asset as it is 
applied in the CIP version 5 Standards. NERC states that the results of 
the survey indicate that, in general, the application of the BES Cyber 
Asset definition, and the 15 minute parameter in particular, resulted 
in the identification of BES Cyber Assets consistent with the language 
and intent of the CIP version 5 Standards.\11\ NERC maintained that the 
survey results demonstrate that the definition of BES Cyber Asset 
provides a sound basis for identifying the types of Cyber Assets that 
should be subject to the cyber security protections required by the CIP 
Reliability Standards.\12\

D. April 29, 2014 Technical Conference

    8. On April 29, 2014, a staff-led technical conference was held 
pursuant to a directive in Order No. 791.\13\ The topics discussed at 
the technical conference included: (1) The adequacy of the approved CIP 
version 5 Standards' protections for Bulk-Power System data being 
transmitted over data networks; (2) whether additional security 
controls are needed to protect Bulk-Power System communications 
networks, including remote systems access; and (3) the functional 
differences between the respective methods utilized for the 
identification,

[[Page 43356]]

categorization, and specification of appropriate levels of protection 
for cyber assets using the CIP version 5 Standards as compared with 
those employed within the NIST Cybersecurity Framework.

---------------------------------------------------------------------------

    9. With respect to the current state of protection for 
communications networks under the CIP version 5 Standards, some 
panelists opined that the CIP version 5 Standards lack controls to: (1) 
Protect communications outside of the Electronic Security Perimeter; 
(2) protect data in motion; (3) authenticate messages and commands to 
BES Cyber Assets; and (4) protect systems or communications using non 
routable protocols. On the subject of the adequacy of protections for 
Bulk-Power System data under the CIP version 5 Standards, several 
panelists stated that stronger measures, such as encryption, would 
enhance the overall protection for Bulk-Power System communications. 
However, other panelists also stated that encryption was not a 
universal solution because it could cause unacceptable latency (i.e., 
time delay in communications) in certain applications.
    10. Regarding the need for additional security controls for Bulk-
Power System communications, panelists identified a number of 
worthwhile steps that could be explored to enhance remote access. 
Suggestions included the adoption of additional physical security 
controls, integrity checks, encryption (in certain cases), out of 
bounds detection for communications links, and coordination with 
vendors to enhance risk management. In addition, certain panelists 
stated their position that the use of intermediate systems, alone, is 
not sufficient to address remote access concerns.\14\ Several panelists 
identified suggestions that could be explored to enhance protections 
for remote access, including the addition of logical or physical 
controls to provide additional network segmentation behind the 
intermediate systems.\15\
---------------------------------------------------------------------------

    \14\ An Intermediate System is defined as ``A Cyber Asset or 
collection of Cyber Assets performing access control to restrict 
Interactive Remote Access to only authorized users. The Intermediate 
System must not be located inside the Electronic Security 
Perimeter.'' NERC Glossary at 46 (April 29, 2015).

---------------------------------------------------------------------------

E. NERC Petition

    11. On February 13, 2015, NERC submitted a petition seeking 
approval of Reliability Standards CIP-003-6, CIP-004-6, CIP-006-6, CIP-
007-6, CIP-009-6, CIP-010-2, and CIP-011-2, as well as the proposed 
implementation plan,\16\ associated violation risk factor and violation 
severity level assignments, proposed new or revised definitions,\17\ 
and retirement of Reliability Standards CIP-003-5, CIP-004-5.1, CIP-
006-5, CIP-007-5, CIP-009-5, CIP-010-1, and CIP-011-1.\18\ NERC states 
that the proposed Reliability Standards are just, reasonable, not 
unduly discriminatory or preferential, and in the public interest 
because they satisfy the factors set forth in Order No. 672 that the 
Commission applies when reviewing a proposed Reliability Standard.\19\ 
NERC maintains that the proposed Reliability Standards ``improve the 
cybersecurity protections required by the CIP Reliability 
Standards[.]'' \20\
---------------------------------------------------------------------------

    \16\ The proposed implementation plan is designed to match the 
effective dates of the proposed Reliability Standards with the 
effective dates of the prior versions of those Reliability Standards 
under the implementation plan of the CIP version 5 Standards.
    \17\ The six new or revised definitions proposed for inclusion 
in the NERC Glossary are: (1) BES Cyber Asset; (2) Protected Cyber 
Asset; (3) Low Impact Electronic Access Point; (4) Low Impact 
External Routable Connectivity; (5) Removable Media; and (6) 
Transient Cyber Asset.
    \18\ The proposed Reliability Standards are available on the 
Commission's eLibrary document retrieval system in Docket No. RM15-
14-000 and on the NERC Web site, www.nerc.com.
    \19\ See NERC Petition at 13 and Exhibit C (citing Order No. 
672, FERC Stats. & Regs. ] 31,204 at PP 323-335).
    \20\ NERC Petition at 4.
---------------------------------------------------------------------------

    12. NERC avers that the proposed CIP Reliability Standards satisfy 
the Commission directives in Order No. 791. Specifically, NERC states 
that the proposed Reliability Standards remove the ``identify, assess, 
and correct'' language, which represents the Commission's preferred 
approach to addressing the underlying directive.\21\ In addition, NERC 
states that the proposed Reliability Standards address the Commission's 
directive regarding a lack of specific controls or objective criteria 
for Low Impact BES Cyber Systems by requiring responsible entities ``to 
implement cybersecurity plans for assets containing Low Impact BES 
Cyber Systems to meet specific security objectives relating to: (i) 
Cybersecurity awareness; (ii) physical security controls; (iii) 
electronic access controls; and (iv) Cyber Security Incident 
response.'' \22\
---------------------------------------------------------------------------

---------------------------------------------------------------------------

    13. With regard to the Commission's directive that NERC develop 
specific controls to protect transient electronic devices (e.g., thumb 
drives and laptop computers), NERC explains that the proposed 
Reliability Standards require responsible entities ``to implement 
controls to protect transient devices connected to their high impact 
and medium impact BES Cyber Systems and associated [Protected Cyber 
Assets].'' \23\ In addition, NERC states that the proposed Reliability 
Standards address the protection of communication networks ``by 
requiring entities to implement security controls for nonprogrammable 
components of communication networks at Control Centers with high or 
medium impact BES Cyber Systems.'' \24\ Finally, NERC explains that it 
has not proposed a definition of the term ``communication network'' 
because the term is not used in the CIP Reliability Standards. 
Additionally, NERC states that ``any proposed definition would need to 
be sufficiently broad to encompass all components in a communication 
network as they exist now and in the future.'' \25\ NERC concludes that 
the proposed Reliability Standards ``meet the ultimate security 
objective of protecting communication networks (both programmable and 
nonprogrammable communication network components).'' \26\

---------------------------------------------------------------------------

    14. Accordingly, NERC requests that the Commission approve the 
proposed Reliability Standards, the proposed implementation plan, the 
associated violation risk factor and violation severity level 
assignments, and the proposed new and revised definitions. NERC 
requests an effective date for the Reliability Standards of the later 
of April 1, 2016 or the first day of the first calendar quarter that is 
three months after the effective date of the Commission's order 
approving the proposed Reliability Standard, although NERC proposes 
that responsible entities will not have to comply with the requirements 
applicable to Low Impact BES Cyber Systems (CIP-003-6, Requirement R1, 
Part 1.2 and Requirement R2) until April 1, 2017.

II. Discussion

    15. Pursuant to section 215(d)(2) of the FPA, we propose to approve 
Reliability Standards CIP-003-6, CIP-004-6, CIP-006-6, CIP-007-6, CIP-
009-6, CIP-010-2 and CIP-011-2 as just, reasonable, not unduly 
discriminatory or preferential, and in the public interest. In 
addition, pursuant to FPA section 215(d)(5), we propose to direct NERC 
to develop certain modifications to Reliability Standard CIP-006-6 and 
to develop requirements addressing supply chain management.

[[Page 43357]]

    16. The proposed Reliability Standards address the Commission's 
directives from Order No. 791 and are an improvement over the current 
Commission-approved CIP Reliability Standards. Specifically, we propose 
to approve the removal of the ``identify, assess, and correct'' 
language in certain requirements of the CIP version 5 Standards. We 
also propose to approve NERC's submission regarding the protection of 
Low Impact BES Cyber Systems. With regard to the directive to create a 
NERC Glossary definition for the term ``communication networks,'' we 
propose to approve NERC's proposal as an equally effective and 
efficient method to achieve the reliability goal underlying that 
directive in Order No. 791.
    17. The technical controls in proposed Reliability Standard CIP-
006-6, which addresses the protection of non-programmable components of 
communication networks (i.e., network cabling and switches), are 
generally consistent with the type of controls cited by the Commission 
in Order No. 791.\27\ We are concerned, however, that the limited 
applicability of the proposed standard, i.e., BES Cyber Assets within 
the same Electronic Security Perimeter but located outside of a 
Physical Security Perimeter, results in a reliability gap. For the 
reasons discussed below, we propose to direct that NERC modify 
Reliability Standard CIP-006-6 to require physical or logical 
protections for communication network components between all bulk 
electric system Control Centers.
---------------------------------------------------------------------------

    \27\ See Order No. 791, 145 FERC ] 61,160 at P 149.
---------------------------------------------------------------------------

    18. Separately, we are concerned that changes in the bulk electric 
system cyber threat landscape, identified through recent malware 
campaigns targeting supply chain vendors, have highlighted a gap in the 
protections under the CIP Reliability Standards. These malware 
campaigns represent a new type of threat to the reliability of the bulk 
electric system where malicious code can infect the software of 
industrial control systems used by responsible entities. Therefore, we 
propose to direct NERC to develop a new Reliability Standard or 
modified Reliability Standard to provide security controls for supply 
chain management for industrial control system hardware, software, and 
services associated with bulk electric system operations.
    19. We also propose to approve the new or revised definitions for 
inclusion in the NERC Glossary, and seek comment on the proposed 
definition for Low Impact External Routable Connectivity. Depending on 
the comments received, we may direct NERC to develop modifications to 
this definition to eliminate possible ambiguities and ensure that BES 
Cyber Assets receive adequate protection.
    20. In addition, we propose to accept 19 violation risk factor and 
violation severity level assignments associated with the proposed 
Reliability Standards. Finally, we propose to approve NERC's proposed 
implementation plan and effective date. Below, we discuss the following 
matters: (A) Identify, assess, and correct language; (B) enhanced 
security controls for Low Impact assets; (C) protection of Transient 
Devices; (D) protection of bulk electric system communication networks; 
(E) supply chain management; (F) proposed definitions; (G) NERC's 
proposed implementation plan; and (H) proposed violation severity level 
and violation risk factor assignments.

A. Identify, Assess, and Correct Language

Order No. 791
    21. In the proposed CIP version 5 Standards, NERC included language 
in 17 CIP requirements that would have required responsible entities to 
implement requirements in a manner to ``identify, assess, and correct'' 
deficiencies.\28\ In Order No. 791, the Commission concluded that the 
``identify, assess, and correct'' language proposed by NERC was unclear 
with respect to the obligations it would impose on responsible 
entities, how it would be implemented by responsible entities, and how 
it would be enforced.\29\ The Commission explained that proposed 
Reliability Standards should be clear and unambiguous regarding what is 
required for compliance and who is required to comply.\30\ The 
Commission directed NERC, pursuant to section 215(d)(5) of the FPA, to 
develop modifications to the CIP version 5 Standards to address the 
Commission's concerns with the ``identify, assess, and correct'' 
language. The Commission stated its preference that NERC should remove 
the ``identify, assess, and correct'' language from the 17 CIP version 
5 requirements, while retaining the substantive provisions of those 
requirements.\31\

NERC Petition
    22. In its Petition, NERC explains that it has addressed the Order 
No. 791 directive regarding the ``identify, assess, and correct'' 
language by removing the language from the 17 requirements that 
included the language in the CIP version 5 Standards.\32\ NERC states 
that it is addressing the concerns underlying the development of the 
``identify, assess, and correct'' language through ``transformation of 
its [Compliance Monitoring and Enforcement Program] and the 
implementation of a risk-based approach to compliance monitoring and 
enforcement activities.'' \33\ NERC explains that the changes it is 
making to the Compliance Monitoring and Enforcement Program, outside 
the text of a reliability standard, ``directly accomplish the goal of 
the `identify, assess, and correct' language by focusing ERO and 
industry resources on those areas that pose a more-than-minimal risk to 
reliability and helping to improve internal controls.'' \34\

Discussion
    23. NERC's proposal to remove the ``identify, assess, and correct'' 
language from the 17 requirements that included the language in the CIP 
version 5 Standards, while retaining the substantive provisions of 
those requirements, reflects the Commission's preferred approach 
outlined in Order No. 791.\35\ Consistent with the rationale underlying 
the Order No. 791 directive, removing the ``identify, assess, and 
correct'' language avoids the possibility of inconsistent application 
and enforcement of the requirements at issue by eliminating the 
possibility of multiple interpretations of that language.
---------------------------------------------------------------------------

    \35\ Order No. 791, 145 FERC ] 61,160 at P 67.
---------------------------------------------------------------------------

    24. Accordingly, we propose to approve NERC's removal of the 
``identify, assess, and correct'' language from the 17 affected 
requirements.

B. Enhanced Security Controls for Low Impact Assets

Order No. 791
    25. In Order No. 791, the Commission approved NERC's new approach 
to categorizing BES Cyber Systems based on the High, Medium or Low 
Impact that each system could have on the reliable operation of the 
bulk electric system. Specifically, the Commission noted that the new 
tiered approach, ``which requires at least a minimum classification of 
Low Impact for BES

[[Page 43358]]

Cyber Systems, better assures the protection of assets that can cause 
cyber security risks to the bulk electric system.'' \36\ The 
Commission, however, raised concerns that the CIP version 5 Standards 
do not require any specific controls for BES Cyber Systems classified 
as Low Impact, nor do the standards contain clear, objective criteria 
``to judge the sufficiency of the controls ultimately adopted by 
responsible entities for Low Impact BES Cyber Systems.'' \37\ The 
Commission concluded that the lack of objective criteria to evaluate 
any controls adopted under proposed Reliability Standard CIP-003-5, 
Requirement R2 ``introduces an unacceptable level of ambiguity and 
potential inconsistency into the compliance process,'' resulting in an 
unnecessary gap in reliability.\38\ The Commission therefore directed 
NERC, pursuant to section 215(d)(5) of the FPA, to develop 
modifications to the CIP version 5 Standards to address the ambiguity 
and potential for inconsistency in the compliance process created by 
the lack of objective criteria pertaining to Low Impact BES Cyber 
Systems.\39\

    \39\ Id. P 108.
---------------------------------------------------------------------------

    26. While not directing NERC to develop specific controls for Low 
Impact BES Cyber Systems, the Commission noted that NERC could address 
the lack of objective criteria in a number of ways, including: (1) 
Requiring specific controls for Low Impact assets, including 
subdividing the assets into different categories with different defined 
controls applicable to each subcategory; (2) developing objective 
criteria against which the controls adopted by responsible entities can 
be compared and measured in order to evaluate their adequacy, including 
subdividing the assets into different categories with different defined 
control objectives applicable to each subcategory; (3) defining with 
greater specificity the processes that responsible entities must have 
for Low Impact facilities under Reliability Standard CIP-003-5, 
Requirement R2; or (4) another equally efficient and effective 
solution.\40\ Finally, the Commission emphasized that however NERC 
decides to address the Commission's concern, ``the criteria NERC 
proposes for evaluating a responsible entities' protections for Low 
Impact facilities should be clear, objective, commensurate with their 
impact on the system, and technically justified.'' \41\

    27. In its Petition, NERC states that the revised CIP Reliability 
Standards include ``additional specificity regarding the controls that 
responsible entities must implement for protecting their low impact BES 
Cyber Systems.'' \42\ NERC explains that proposed Reliability Standard 
CIP-003-6, Requirement R1 requires responsible entities to develop 
cyber security policies for Low Impact BES Cyber Systems ``to 
communicate management's expectation for cybersecurity across the 
organization.'' \43\ According to NERC, the cyber security policies 
required under proposed Reliability Standard CIP-003-6, Requirement R1 
must include the four subject matter areas addressed by proposed 
Reliability Standard CIP-003-6, Requirement R2, Attachment 1, and must 
be reviewed and approved by the CIP Senior Manager at least once every 
15 calendar months. NERC explains that, while a responsible entity has 
the flexibility to develop either a single comprehensive cyber security 
policy or single high-level umbrella policy with detail provided in 
lower-level documents, ``the purpose of these policies is to 
communicate the responsible entity's management goals, objectives, and 
expectations for the protection of low impact BES Cyber Systems and 
establish a culture of security and compliance across the 
organization.'' \44\

    28. In addition, NERC explains that proposed Reliability Standard 
CIP-003-6, Requirement R2 requires responsible entities with Low Impact 
BES Cyber Systems to implement controls necessary to meet specific 
security objectives for: (1) Cyber security awareness; (2) physical 
security controls; (3) electronic access controls; and (4) cyber 
security incident response. NERC explains further that while the four 
topics addressed by Reliability Standard CIP-003-6, Requirement R2 are 
the same as those under the CIP version 5 Standards, focusing resources 
on the four identified subject matter areas ``will have the greatest 
cybersecurity benefit for low impact BES Cyber Systems without 
diverting resources necessary for the protection of high and medium 
impact BES Cyber Systems.'' \45\

---------------------------------------------------------------------------

    29. NERC explains further that proposed Reliability Standard CIP-
003-6, Requirement R2 provides responsible entities with flexibility to 
adopt security controls for Low Impact BES Cyber Systems ``in the 
manner that best suits the needs and characteristics of their 
organization, so long as the responsible entity can demonstrate that it 
designed its controls to meet the ultimate security objective.'' \46\ 
NERC states that attempts to overly prescribe specific security 
controls would be problematic and could inhibit the development of 
innovative security controls due to the diversity of Low Impact BES 
Cyber Systems. However, NERC explains that by having responsible 
entities articulate clear security objectives, ``the ERO and the 
Commission will have a basis from which to judge the sufficiency of the 
controls ultimately adopted by a responsible entity.'' \47\

Discussion
    30. We propose to approve proposed Reliability Standard CIP-003-6. 
NERC's proposal satisfies the Commission's Order No. 791 directive by 
providing responsible entities with a list of specific security 
objectives relevant to Low Impact BES Cyber Systems that must be 
addressed through one or more documented cyber security plans. 
Reliability Standard CIP-003-6, Requirement R2 provides clarity 
regarding what is expected for compliance and requires responsible 
entities to implement specific security controls to meet the four 
subject matter areas identified by NERC to address the risks associated 
with Low Impact BES Cyber Systems, providing enhanced protections for 
Low Impact assets.
    31. As noted above, Attachment 1 to revised CIP-003-6, Requirement 
R2 identifies four topics addressed by the requirement, and describes 
the affirmative obligations associated with each topic, including: (1) 
Mandatory reinforcement of cyber security awareness practices at least 
once every 15 calendar months; (2) mandatory physical access controls 
to the asset or locations of the Low Impact BES Cyber Systems within 
the asset and Low Impact BES Cyber System Electronic Access Points, if 
any; (3) mandatory electronic access point protection to permit only 
necessary inbound and outbound bi-directional routable protocol access 
and mandatory authentication for all dialup connectivity that provides 
access to the Low Impact BES Cyber System; and (4) specific information 
to be included in

[[Page 43359]]

incident response plans. We believe that Attachment 1 provides 
sufficient context to evaluate objectively the effectiveness of the 
procedures developed by a responsible entity to implement CIP-003-6 and 
judge the sufficiency of the controls ultimately adopted by a 
responsible entity under its security plans.
    32. Furthermore, we agree that NERC's proposal to use clear 
security objectives in lieu of specific security controls for each Low 
Impact system is reasonable owing to the diversity of assets covered 
under the Low Impact category. With respect to the security subject 
matter areas covered under proposed CIP-003-6, we believe that NERC's 
proposal is reasonable in relation to the risk posed by Low Impact BES 
Cyber Systems, as well as the diversity of systems captured by the Low 
Impact category. Therefore, we propose to approve proposed Reliability 
Standard CIP-003-6.

C. Protection of Transient Devices

Order No. 791
    33. In Order No. 791, the Commission approved the proposed 
definition of BES Cyber Asset that provides, in part, that ``[a] Cyber 
Asset is not a BES Cyber Asset if, for 30 consecutive calendar days or 
less, it is directly connected to a network within an [Electronic 
Security Perimeter], a Cyber Asset within an [Electronic Security 
Perimeter], or to a BES Cyber Asset, and it is used for data transfer, 
vulnerability assessment, maintenance, or troubleshooting purposes.'' 
\48\ While the Commission had requested comment in the CIP version 5 
NOPR on whether the 30 consecutive calendar day qualifier in the 
proposed definition of BES Cyber Asset ``could result in the 
introduction of malicious code or new attack vectors to an otherwise 
trusted and protected system,'' \49\ the Commission concluded, based on 
comments, that ``it would be unduly burdensome to protect transient 
devices in the same manner as BES Cyber Assets because transient 
devices are portable and frequently connected and disconnected from 
systems.'' \50\

    34. While accepting the 30-day exemption in the BES Cyber Asset 
definition, the Commission reiterated its concern whether the 
provisions of the CIP version 5 Standards ``provide adequately robust 
protection from the risks posed by transient devices.'' \51\ Therefore, 
the Commission directed that NERC, pursuant to section 215(d)(5) of the 
FPA, develop either new or modified Reliability Standards to address 
the reliability risks posed by connecting transient devices to BES 
Cyber Assets and Systems. In particular, the Commission stated that it 
expects NERC to consider the following security elements for transient 
devices and removable media: (1) Device authorization as it relates to 
users and locations; (2) software authorization; (3) security patch 
management; (4) malware prevention; (5) detection controls for 
unauthorized physical access to a transient device; and (6) processes 
and procedures for connecting transient devices to systems at different 
security classification levels (i.e., High, Medium, Low Impact).\52\

NERC Petition
    35. In its Petition, NERC states that the revised CIP Reliability 
Standards satisfy the Commission's directive in Order No. 791 by 
requiring that applicable entities: (1) Develop plans and implement 
cybersecurity controls to protect Transient Cyber Assets and Removable 
Media associated with their High Impact and Medium Impact BES Cyber 
Systems and associated Protected Cyber Assets; and (2) train their 
personnel on the risks associated with using Transient Cyber Assets and 
Removable Media. NERC states that the purpose of the proposed revisions 
is to prevent unauthorized access to and use of transient devices, 
mitigate the risk of vulnerabilities associated with unpatched software 
on transient devices, and mitigate the risk of the introduction of 
malicious code on transient devices. NERC explains that the standard 
drafting team determined that the proposed requirements should only 
apply to transient devices associated with High and Medium Impact BES 
Cyber Systems, concluding that ``the application of the proposed 
transient devices requirements to transient devices associated with low 
impact BES Cyber Systems was unnecessary, and likely counterproductive, 
given the risks low impact BES Cyber Systems present to the Bulk 
Electric System.'' \53\
---------------------------------------------------------------------------

    \53\ NERC Petition at 34-35.
---------------------------------------------------------------------------

    36. NERC proposes to add two terms to the NERC Glossary, Transient 
Cyber Asset and Removable Media, to clarify the types of transient 
devices subject to the CIP Reliability Standards. NERC also proposes to 
revise the definitions for BES Cyber Asset and Protected Cyber Asset to 
remove the 30-day exemption as the proposed definition for Transient 
Cyber Assets obviates the need for the 30-day exemption language. NERC 
indicates that, as defined, Transient Cyber Assets and Removable Media 
do not provide reliability services and are not part of the BES Cyber 
System to which they are connected.\54\
---------------------------------------------------------------------------

    \54\ Id. at 36-37.
---------------------------------------------------------------------------

    37. NERC proposes to define Transient Cyber Asset as: ``A Cyber 
Asset that (i) is capable of transmitting or transferring executable 
code, (ii) is not included in a BES Cyber System, (iii) is not a 
Protected Cyber Asset (PCA) and (iv) is directly connected (e.g., using 
Ethernet, serial, Universal Serial Bus, or wireless, including near 
field or Bluetooth communication) for 30 consecutive calendar days or 
less to a BES Cyber Asset, a network within an [Electronic Security 
Perimeter], or a [Protected Cyber Asset].'' NERC explains that examples 
of Transient Cyber Assets include but are not limited to: Diagnostic 
test equipment, packet sniffers, equipment used for BES Cyber System 
maintenance, equipment used for BES Cyber System configuration or 
equipment used to perform vulnerability assessments, and may include 
devices or platforms such as laptops, desktops or tablet computers 
which run applications that support BES Cyber Systems.\55\
---------------------------------------------------------------------------

    \55\ Id. at 36.
---------------------------------------------------------------------------

    38. NERC proposes to define the term Removable Media as: ``Storage 
media that (i) are not Cyber Assets, (ii) are capable of transferring 
executable code, (iii) can be used to store, copy, move, or access 
data, and (iv) are directly connected for 30 consecutive calendar days 
or less to a BES Cyber Asset, a network within an [Electronic Security 
Perimeter] or a Protected Cyber Asset. Examples include but are not 
limited to floppy disks, compact disks, USB flash drives, external hard 
drives and other flash memory cards/drives that contain nonvolatile 
memory.'' \56\
---------------------------------------------------------------------------

    \56\ Id. at 36.
---------------------------------------------------------------------------

    39. NERC explains that proposed Reliability Standard CIP-010-2, 
Requirement R4 requires entities to document and implement a plan for 
managing and protecting Transient Cyber Assets and Removable Media in 
order to protect BES Cyber Systems from the risks associated with 
transient devices. Specifically, Requirement R4 provides that ``[e]ach 
responsible entity for its high impact and medium impact BES Cyber 
Systems and associated Protected Cyber Assets, shall implement, except 
under CIP Exceptional Circumstances, one or more documented plans for 
Transient Cyber

[[Page 43360]]

Assets and Removable Media that include the sections in Attachment 1 
[to the proposed standard].'' NERC indicates that Attachment 1 does not 
prescribe a standard method or set of controls that each entity must 
implement to protect its transient devices, but rather requires 
responsible entities to meet certain security objectives by 
implementing the controls that the responsible entity determines are 
necessary to meet its affirmative obligation to protect BES Cyber 
Systems.\57\
---------------------------------------------------------------------------

    \57\ Id. at 37.
---------------------------------------------------------------------------

    40. NERC further explains that Attachment 1 to CIP-010-2, 
Requirement R4 requires a responsible entity to adopt controls to 
address the following areas: (1) Protections for Transient Cyber Assets 
managed by responsible entities; (2) protections for Transient Cyber 
Assets managed by another party; and (3) protections for Removable 
Media. NERC indicates that these provisions reflect the standard 
drafting team's recognition that the security controls required for a 
particular transient device must account for (1) the functionality of 
that device and (2) whether the responsible entity or a third party 
manages the device. NERC also states that, because Transient Cyber 
Assets and Removable Media have different capabilities, they present 
different levels of risk to the bulk electric system.\58\

Discussion
    41. Based on our review, proposed Reliability Standard CIP-010-2 
appears to provide a satisfactory level of security for transient 
devices used at High and Medium Impact BES Cyber Systems. As described 
above, proposed Reliability Standard CIP-010-2, Requirement R4 
addresses the following security elements: (1) Device authorization; 
(2) software authorization; (3) security patch management; (4) malware 
prevention; and (5) unauthorized use. The proposed security controls, 
taken together, constitute a reasonable approach to address the 
reliability objectives outlined by the Commission in Order No. 791. The 
proposed security controls outlined in Attachment 1 should ensure that 
responsible entities apply multiple security controls to provide 
defense-in-depth protection to transient devices (i.e., transient cyber 
assets and removable media) in the High and Medium Impact BES Cyber 
System environments.
    42. We are concerned, however, that NERC's proposed revisions do 
not provide adequate security controls to address the risks posed by 
transient devices used at Low Impact BES Cyber Systems, including Low 
Impact control centers, due to the limited applicability of Requirement 
R4. We believe that this omission may result in a gap in protection for 
Low Impact BES Cyber Systems. For example, malware inserted via a USB 
flash drive at a single Low Impact substation could propagate through a 
network of many substations without encountering a single security 
control under NERC's proposal. In addition, we note that Low Impact 
security controls do not provide for the use of mandatory anti-malware/
antivirus protections within the Low Impact facilities, heightening the 
risk that malware or malicious code could propagate through these 
systems without being detected.
    43. We do not believe that NERC has provided an adequate 
justification to limit the applicability of Reliability Standard CIP-
010-2. In its petition, NERC states that ``the application of the 
proposed transient devices requirements to transient devices associated 
with low impact BES Cyber Systems was unnecessary, and likely 
counterproductive, given the risks low impact BES Cyber Systems present 
to the Bulk Electric System.'' \59\ Essentially, NERC posits that 
resources are better placed in the protection of High and Medium Impact 
devices. The burden of expanding the applicability of Reliability 
Standard CIP-010-2 to transient devices at Low Impact BES Cyber 
Systems, however, is not clear from the information in the record. Nor 
is it clear what information and analysis led NERC to conclude that the 
application of the transient device requirements to Low Impact BES 
Cyber Systems ``was unnecessary.'' \60\ Therefore, we direct NERC to 
provide additional information supporting the proposed limitation in 
Reliability Standard CIP-010-2 to High and Medium Impact BES Cyber 
Systems. Depending on the information provided, we may direct NERC to 
address the potential reliability gap by developing a solution, which 
could include modifying the applicability section of CIP-010-2, 
Requirement R4 to include Low Impact BES Cyber Systems, that 
effectively addresses, and is appropriately tailored to address, the 
risks posed by transient devices to Low Impact BES Cyber Systems.

D. Protection of Bulk Electric System Communication Networks

Order No. 791
    44. In Order No. 791, the Commission approved a revised definition 
of the NERC Glossary term Cyber Asset, including the removal of the 
phrase ``communication networks.'' In reaching its decision, the 
Commission recognized that maintaining the phrase ``communication 
networks'' in the definition of ``cyber asset'' could cause confusion 
and potentially complicate implementation of the CIP version 5 
Standards ``as many communication network components, such as cabling, 
cannot strictly comply with the CIP Reliability Standards.'' \61\
---------------------------------------------------------------------------

    \61\ Order No. 791, 145 FERC ] 61,160 at P 148.
---------------------------------------------------------------------------

    45. However, while the Commission approved the revised Cyber Asset 
definition, the Commission also directed NERC to create a definition of 
communication networks. Specifically, the Commission stated that 
``[t]he definition of communication networks should define what 
equipment and components should be protected, in light of the statutory 
inclusion of communication networks for the reliable operation of the 
Bulk-Power System.'' \62\
---------------------------------------------------------------------------

    \62\ Id. P 150.
---------------------------------------------------------------------------

    46. The Commission also directed NERC to develop new or modified 
Reliability Standards to address the reliability gap resulting from the 
removal of the phrase ``communication networks'' from the Cyber Asset 
definition. Specifically, the Commission found that a gap in protection 
may exist since the CIP version 5 Standards ``do not address security 
controls needed to protect the nonprogrammable components of 
communication networks.'' \63\ The Commission explained that the new or 
modified Reliability Standards should require appropriate and 
reasonable controls to protect the non-programmable aspects of 
communication networks.\64\ The Commission provided examples of other 
relevant information security standards that address the protection of 
the nonprogrammable aspects of communication networks by requiring, 
among other things, locked wiring closets, disconnected or locked spare 
jacks, protection of cabling by conduit or cable trays, or generally 
emphasizing the protection of communication network cabling from 
interception or damage.\65\

NERC Petition
    47. In its petition, NERC states that the standard drafting team 
concluded that it did not need to create a new definition for 
communication networks to address the Commission's concerns. NERC 
explains that the term communication network ``is generally understood 
to encompass both programmable and nonprogrammable components (i.e., a 
communication network includes computer peripherals, terminals, and 
databases as well as communication mediums such as wires).'' \66\ 
Therefore, NERC concludes that any proposed definition of communication 
network ``would need to be sufficiently broad to encompass all 
components in a communication network as they exist now and in the 
future.'' \67\ NERC explains that, based on that conclusion, the 
standard drafting team identified the types of equipment and components 
that responsible entities must protect, and developed reasonable 
controls to secure those components based on the risk they pose to the 
bulk electric system, rather than develop a specific definition.

---------------------------------------------------------------------------

    48. NERC states that the revised CIP Reliability Standards, as 
proposed, address the ultimate security objective of protecting both 
the programmable and nonprogrammable components of communication 
networks.\68\ NERC explains that the proposed standards include 
protections for cables and other nonprogrammable components of 
communication networks through proposed Reliability Standard CIP-006-6, 
Requirement R1, Part 1.10, which augments the existing protections for 
programmable communication components by requiring entities to 
implement various security controls to restrict and manage physical 
access to Physical Security Perimeters.\69\ NERC further states that 
the standard drafting team focused on nonprogrammable communication 
components at control centers with High or Medium Impact BES Cyber 
Systems because those locations present a heightened risk to the Bulk-
Power System, warranting the increased protections.\70\

---------------------------------------------------------------------------

    49. NERC explains that proposed Reliability Standard CIP-006-6, 
Requirement R1, Part 1.10 provides that, for High and Medium Impact BES 
Cyber Systems and their associated Protected Cyber Assets, responsible 
entities must restrict physical access to cabling and other 
nonprogrammable communication components used for connection between 
covered Cyber Assets within the same Electronic Security Perimeter in 
those instances when such cabling and components are located outside of 
a Physical Security Perimeter. NERC explains further that, where 
physical access restrictions to such cabling and components are not 
feasible, Part 1.10 provides that the responsible entity must document 
and implement encryption of data transmitted over such cabling and 
components and/or monitor the status of the communication link composed 
of such cabling and components. Further, pursuant to Part 1.10, a 
responsible entity must issue an alarm or alert in response to detected 
communication failures to the personnel identified in the BES Cyber 
Security Incident response plan within 15 minutes of detection, or 
implement an equally effective logical protection.\71\
---------------------------------------------------------------------------

    \71\ Id. at 48-49.
---------------------------------------------------------------------------

    50. NERC states that proposed Reliability Standard CIP-006-6 
provides flexibility for responsible entities to implement the physical 
security measures that best suit their needs and to account for 
configurations where logical measures are necessary because the entity 
cannot implement physical access restrictions effectively. Responsible 
entities have the discretion as to the type of physical or logical 
protections to implement pursuant to Part 1.10, provided that the 
protections are designed to meet the overall security objective. 
According to NERC, the protections required by Part 1.10 will reduce 
the possibility of tampering and the likelihood that ``man-in-the-
middle'' attacks could compromise the integrity of BES Cyber Systems or 
Protected Cyber Assets at control centers with High or Medium Impact 
BES Cyber Systems.\72\
---------------------------------------------------------------------------

    \72\ Id. at 49-50.
---------------------------------------------------------------------------

    51. NERC explains that proposed Part 1.10 applies only to 
nonprogrammable components outside of a Physical Security Perimeter 
because nonprogrammable components located within a Physical Security 
Perimeter are already subject to physical security protections by 
virtue of their location. NERC further states that Part 1.10 only 
applies to nonprogrammable components used for connection between 
applicable Cyber Assets within the same Electronic Security Perimeter 
because Reliability Standard CIP-005-5 already requires logical 
protections for communications between discrete Electronic Security 
Perimeters.\73\
---------------------------------------------------------------------------

    \73\ Id. at 49.
---------------------------------------------------------------------------

    52. In addition, NERC asserts that the proposed Reliability 
Standards will strengthen the defense-in-depth approach by further 
minimizing the ``attack surface'' of BES Cyber Systems. NERC also 
clarifies that the standard drafting team limited the applicability in 
this manner to clarify that responsible entities are not responsible 
for protecting nonprogrammable communication components outside of the 
responsible entity's control (i.e., components of a telecommunication 
carrier's network).\74\
---------------------------------------------------------------------------

    \74\ Id. at 51.
---------------------------------------------------------------------------

Discussion
    53. We believe that NERC's proposed alternative approach to 
addressing the Commission's Order No. 791 directive regarding the 
definition of communication networks adequately addresses part of the 
underlying concerns set forth in Order No. 791. Proposed Reliability 
Standard CIP-006-6, Requirement R1.10 specifies the types of assets 
subject to mandatory protection by using the existing definitions of 
Electronic Security Perimeter \75\ and Physical Security Perimeter.\76\ 
Proposed Reliability Standard CIP-006-6 addresses protection for non-
programmable components of communication networks, such as network 
cabling and switches, that are located within the same Electronic 
Security Perimeter, but span separate Physical Security Perimeters. 
Specifically, proposed Reliability Standard CIP-006-6 requires 
responsible entities to restrict physical access to cabling and other 
nonprogrammable communication components between BES Cyber Assets 
within the same Electronic Security Perimeter in those instances when 
such cabling and components are located outside of a Physical Security 
Perimeter. Where physical access restrictions to such cabling and 
components is not feasible, Part 1.10 provides that responsible 
entities must document and implement encryption of data transmitted 
over such cabling and components, monitor the status of the

[[Page 43362]]

communication link composed of such cabling and components, or 
implement an equally effective logical protection.
---------------------------------------------------------------------------

    \75\ Electronic Security Perimeter: The logical border 
surrounding a network to which Critical Cyber Assets are connected 
and for which access is controlled. See NERC Glossary at 33.
    \76\ Physical Security Perimeter: The physical, completely 
enclosed (``six-wall'') border surrounding computer rooms, 
telecommunications rooms, operations centers, and other locations in 
which Critical Cyber Assets are housed and for which access is 
controlled. See NERC Glossary at 60.
---------------------------------------------------------------------------

    54. We propose to accept NERC's proposed omission of a definition 
of communication networks based on NERC's explanation that responsible 
entities must develop controls to secure the non-programmable 
components of communication networks based on the risk they pose to the 
bulk electric system, rather than develop a specific definition of 
communication networks to identify assets for protection. NERC's 
proposal is an equally efficient and effective solution to the 
Commission's directive in Order No. 791 that NERC develop a definition 
of communication networks, subject to the proposed modification 
discussed below.
    55. NERC's proposed solution for the protection of nonprogrammable 
components of communication networks, however, does not fully meet the 
intent of the Commission's Order No. 791 directive, resulting in a gap 
in security for bulk electric system communication systems. While the 
technical substance of CIP-006-6, Requirement R1, Part 1.10 appears to 
be adequate, we are concerned that the limited applicability of the 
provision results in limited protection for the nonprogrammable 
components of the communication systems at issue. Specifically, 
proposed CIP-006-6, Requirement R1, Part 1.10 would only apply to 
nonprogrammable components of communication networks within the same 
Electronic Security Perimeter, excluding from protection other 
programmable and non-programmable communication network components that 
may exist outside of a discrete Electronic Security Perimeter.
    56. While NERC asserts that this limitation is justified by the 
controls required under Reliability Standard CIP-005-5, NERC's position 
does not appear to consider that the controls set forth in Reliability 
Standard CIP-005-5 are limited to interactive remote access into an 
Electronic Security Perimeter, and can only be applied on programmable 
electronic devices and data that exists within an Electronic Security 
Perimeter.\77\ This limitation would exclude communication network 
components that may be necessary to facilitate the automated 
transmission of reliability data between bulk electric system Control 
Centers in discrete Electronic Security Perimeters and would also 
exclude real time monitoring data that is used by Reliability 
Coordinators to monitor and assess the operation of their control 
areas. In other words, revised Reliability Standard CIP-006-6, 
Requirement R1 provides mandatory protection against: (1) Physical 
attacks on nonprogrammable equipment; (2) man-in-the-middle attacks; 
and (3) session hijacking attacks within the confines of a bulk 
electric system Control Center, but does not extend protections to 
real-time data passing between Control Centers outside of a facility.
---------------------------------------------------------------------------

    \77\ See Reliability Standard CIP-005-5 (Electronic Security 
Perimeters), Requirement R2.
---------------------------------------------------------------------------

    57. Comments from participants at the April 29, 2014 Technical 
Conference suggest that the Commission should take action to ensure the 
confidentiality, integrity, and availability of sensitive bulk electric 
system data when it is in motion both inside and outside of an 
Electronic Security Perimeter.\78\ We understand that inter-Control 
Center communications play a vital role in maintaining bulk electric 
system reliability and, as a result, we believe that the communication 
links and data used to control and monitor the bulk electric system 
should receive protection under the CIP Reliability Standards.
---------------------------------------------------------------------------

    \78\ See Transcript at pp. 19, 24, 74-75 (Kevin Perry speaking), 
79 (Mikhail Falkovich speaking).
---------------------------------------------------------------------------

    58. We also recognize that third party communication infrastructure 
(e.g., facilities owned by a telecommunications company) cannot 
necessarily be physically protected by responsible entities. This fact, 
however, does not alleviate the need to protect reliability data that 
traverses third party communication infrastructure. Proposed 
Reliability Standard CIP-006-6, Requirement R1, Part 1.10 mandates that 
logical controls, such as encryption and connection link monitoring, be 
applied to cabling and components that cannot be physically restricted 
by the responsible entity. However, similar protections are not 
afforded to communications and data leaving bulk electric system 
Control Centers where they may be intercepted and altered while 
traversing communication networks.
    59. Therefore, pursuant to section 215(d)(5) of the FPA, we propose 
to direct NERC to develop a modification to proposed Reliability 
Standard CIP-006-6 to require responsible entities to implement 
controls to protect, at a minimum, all communication links and 
sensitive bulk electric system data communicated between all bulk 
electric system Control Centers. This includes communication between 
two (or more) Control Centers, but not between a Control Center and 
non-Control Center facilities such as substations. Also, if latency 
concerns mitigate against use of encryption as a logical control for 
any inter-Control Center communications, our understanding is that 
other logical protections are available, and we seek comment on this 
point.
    60. Further, as discussed at the April 29, 2014 technical 
conference, panelists identified suggestions that could be explored to 
enhance protections for remote access, including the addition of 
logical or physical controls to provide additional network segmentation 
behind the intermediate systems. For example, the Commission is 
interested in comments that address the value achieved if the CIP 
standards were to require the incorporation of additional network 
segmentation controls, connection monitoring, and session termination 
controls behind responsible entity intermediate systems. We seek 
comment on whether these or other steps to improve remote access 
protection are needed, and whether the adoption of any additional 
security controls addressing this topic would provide substantial 
reliability and security benefits.

E. Risks Posed by Lack of Controls for Supply Chain Management

    61. The information and communications technology and industrial 
control system supply chains provide hardware, software and operations 
support for computer networks. Such supply chains are complex, globally 
distributed and interconnected systems that have geographically diverse 
routes and consist of multiple tiers of outsourcing. The supply chain 
includes public and private sector entities that depend on each other 
to develop, integrate, and use information and communications 
technology and industrial control system supply chain products and 
services. Thus, the supply chain provides the opportunity for 
significant benefits to customers, including low cost, 
interoperability, rapid innovation, a variety of product features and 
choice.
    62. However, the global supply chain also enables opportunities for 
adversaries to directly or indirectly affect the management or 
operations of companies that may result in risks to the end user. 
Supply chain risks may include the insertion of counterfeits, 
unauthorized production, tampering, theft, or insertion of malicious 
software, as well as poor manufacturing and development practices. To 
address these risks, NIST developed SP 800-161 \79\ to

[[Page 43363]]

provide guidance and controls that can be used to comply with Federal 
Information Processing Standard 199 Standards for Security 
Categorization of Federal Information and Information Systems for 
Federal Government Information Systems.\80\ Similarly, the Department 
of Energy has developed guidance on cybersecurity procurement language 
for energy delivery systems.\81\

---------------------------------------------------------------------------

    63. While the Commission did not address supply chain management in 
Order No. 791, changes in the bulk electric system cyber threat 
landscape identified through recent malware campaigns targeting supply 
chain vendors have highlighted a gap in the protections under the CIP 
Standards. Specifically, in 2014, after Order No. 791 was issued, the 
Industry Control System--Computer Emergency Readiness Team (ICS-CERT) 
reported on two focused malware campaigns.\82\ This new type of malware 
campaign is based on the injection of malware while a product or 
service remains in the control of the hardware or software vendor, 
prior to delivery to the customer.
---------------------------------------------------------------------------

    \82\ ICS-CERT is a division of the Department of Homeland 
Security that works to reduce risks within and across all critical 
infrastructure sectors by partnering with law enforcement agencies 
and the intelligence community. See https://ics-cert.us-cert.gov/alerts/ICS-ALERT-14-176-02A; and https://ics-cert.us-cert.gov/alerts/ICS-ALERT-14-281-01B for ``alert'' information on supply 
chain malware campaigns.
---------------------------------------------------------------------------

    64. We believe that it is reasonable to direct NERC to develop a 
new or modified Reliability Standard to provide security controls for 
supply chain management for industrial control system hardware, 
software, and computing and networking services associated with bulk 
electric system operations. The reliability goal should be to create a 
forward-looking, objective-driven standard that encompasses activities 
in the system development life cycle: from research and development, 
design and manufacturing stages (where applicable), to acquisition, 
delivery, integration, operations, retirement, and eventual disposal of 
the Registered Entity's information and communications technology and 
industrial control system supply chain equipment and services. The 
standard should support and ensure security, integrity, quality, and 
resilience of the supply chain and the future acquisition of products 
and services.
    65. Since security controls for supply chain management will likely 
vary greatly with each responsible entity due to variations in 
individual business practices, the right set of supply chain management 
security controls should accommodate for, among other things, an 
entity's: (1) Procurement process; (2) vendor relations; (3) system 
requirements; (4) information technology implementation; and (5) 
privileged commercial or financial information. The following Supply 
Chain Risk Management controls from NIST SP 800-161 may be 
instructional in the development of any new reliability standard to 
address this security topic: \83\ (1) Access Control Policy and 
Procedures; (2) Security Assessment Authorization; (3) Configuration 
Management; (4) Identification and Authentication; (5) System 
Maintenance Policy and Procedures; (6) Personnel Security Policy and 
Procedures; (7) System and Services Acquisition; (8) Supply Chain 
Protection; and (9) Component Authenticity.\84\
---------------------------------------------------------------------------

    \83\ The listed controls do not reflect a comprehensive scope of 
the proposed standard.
    \84\ See NIST SP 800-161.
---------------------------------------------------------------------------

    66. Therefore, pursuant to section 215(d)(5) of the FPA, we propose 
to direct NERC to develop a new reliability standard or modified 
reliability standard to provide security controls for supply chain 
management for industrial control system hardware, software, and 
services associated with bulk electric system operations. In addition 
to the parameters discussed above, due to the broadness of the topic 
and the individualized nature of many aspects of supply chain 
management, we anticipate that a Reliability Standard pertaining to 
supply chain management security would:
     Respect section 215 jurisdiction by only addressing the 
obligations of registered entities. A reliability standard should not 
directly impose obligations on suppliers, vendors or other entities 
that provide products or services to registered entities.
     Be forward-looking in the sense that the reliability 
standard should not dictate the abrogation or re-negotiation of 
currently-effective contracts with vendors, suppliers or other 
entities.
     Recognize the individualized nature of many aspects of 
supply chain management by setting goals (the ``what''), while allowing 
flexibility in how a registered entity subject to the standard achieves 
that goal (the ``how'').\85\
---------------------------------------------------------------------------

    \85\ See Order No. 672, FERC Stats. & Regs. ] 31,204 at P 260.
---------------------------------------------------------------------------

     Given the types of specialty products involved and 
diversity of acquisition processes, the standard may need to allow 
exceptions, e.g., to meet safety requirements and fill operational gaps 
if no secure products are available.
     Provide enough specificity so that compliance obligations 
are clear and enforceable. In particular, we anticipate that a 
reliability standard that simply requires a registered entity to ``have 
a plan'' addressing supply chain management would not suffice. Rather, 
to adequately address our concerns, we believe that a reliability 
standard should identify specific controls. As discussed above, NIST SP 
800-161 may be instructional in identifying appropriate controls in the 
development of an effective supply chain management reliability 
standard.
    We recognize that developing a supply chain management standard 
would likely be a significant undertaking and require extensive 
engagement with stakeholders to define the scope, content, and timing 
of the standard. Accordingly, to further that stakeholder engagement, 
we seek comment on this proposal, including: (1) The general proposal 
to direct that NERC develop a Reliability Standard to address supply 
chain management; (2) the anticipated features of, and requirements 
that should be included in, such a standard; and (3) a reasonable 
timeframe for development of a standard. We also direct staff, after 
receipt and consideration of those comments, to engage in additional 
outreach to further the Commission's consideration of the need for, and 
scope, content, and timing of, a supply chain management standard.

F. Proposed Definitions

    67. The proposed revised CIP Reliability Standards include six new 
or revised definitions for inclusion in the NERC glossary. NERC's 
proposal includes four new definitions and two revised definitions. 
Specifically, NERC seeks approval for the following terms: (1) BES 
Cyber Asset; (2) Protected Cyber Asset; (3) Low Impact Electronic 
Access Point; (4) Low Impact External Routable Connectivity; (5) 
Removable Media; and (6) Transient Cyber Asset. We propose to approve 
the proposed definitions for inclusion in the NERC Glossary. We also 
seek comment on certain aspects of the proposed definition for Low 
Impact External Routable Connectivity, as discussed below. After 
receiving

[[Page 43364]]

comments, depending on the adequacy of the explanations provided in 
response to our questions, we may direct NERC to develop modifications 
to this definition to eliminate ambiguities and assure that the revised 
CIP Reliability Standards provide adequate protection for the bulk 
electric system.
Definition--Low Impact External Routable Connectivity
    68. In its petition, NERC proposes the following definition for Low 
Impact External Routable Connectivity:

    Direct user-initiated interactive access or a direct device-to-
device connection to a low impact BES Cyber System(s) from a Cyber 
Asset outside the asset containing those low impact BES Cyber 
System(s) via a bidirectional routable protocol connection. Point-
to-point communications between intelligent electronic devices that 
use routable communication protocols for time-sensitive protection 
or control functions between Transmission station or substation 
assets containing low impact BES Cyber Systems are excluded from 
this definition (examples of this communication include. but are not 
limited to, IEC 61850 GOOSE or vendor proprietary protocols).\86\
---------------------------------------------------------------------------

    \86\ NERC Petition at 28.

    69. NERC explains that the proposed definition describes the 
scenarios where responsible entities are required to apply Low Impact 
access controls under Reliability Standard CIP-003-6, Requirement R2 to 
their Low Impact assets. Specifically, if Low Impact External Routable 
Connectivity is used, a responsible entity must implement a Low Impact 
Electronic Access Point to permit only necessary inbound and outbound 
bidirectional routable protocol access.\87\
---------------------------------------------------------------------------

    \87\ Id. at 29.
---------------------------------------------------------------------------

    70. We seek comment on the following aspects of the proposed 
definition. First, we seek comment on the purpose of the meaning of the 
term ``direct'' in relation to the phrases ``direct user-initiated 
interactive access'' and ``direct device-to-device connection'' within 
the proposed definition. In addition, we seek comment on the 
implementation of the ``layer 7 application layer break'' contained in 
certain reference diagrams in the Guidelines and Technical Basis 
section of proposed Reliability Standard CIP-003-6.\88\ It appears that 
guidance provided in the Guidelines and Technical Basis section of the 
proposed standard may conflict with the plain reading of the term 
``direct.'' We are concerned that a conflict in the reading of the term 
``direct'' could lead to complications in the implementation of the 
proposed CIP Reliability Standards, hindering the adoption of effective 
security controls for Low Impact BES Cyber Assets. Depending upon the 
responses received, we may direct NERC to develop a modification to the 
definition of Low Impact External Routable Connectivity.

Reference Model 6 at p. 39.
---------------------------------------------------------------------------

G. Implementation Plan

    71. NERC's proposed implementation plan for the proposed 
Reliability Standards is designed to match the effective dates of the 
proposed Reliability Standards with the effective dates of the prior 
versions of the related Reliability Standards under the implementation 
plan of the CIP version 5 Standards. NERC states that the purpose of 
this approach is to provide regulatory certainty by limiting the time, 
if any, that the CIP version 5 Standards with the ``identify, assess, 
and correct'' language would be effective. Specifically, pursuant to 
the CIP version 5 implementation plan, the effective date of each of 
the CIP version 5 Standards is April 1, 2016, except for the effective 
date for Requirement R2 of CIP-003-5, which is April 1, 2017. 
Consistent with those dates, the proposed implementation plan provides 
that: (1) each of the proposed reliability Standards shall become 
effective on the later of April 1, 2016 or the first day of the first 
calendar quarter that is three months after the effective date of the 
Commission's order approving the proposed Reliability Standard; and (2) 
responsible entities will not have to comply with the requirements 
applicable to Low Impact BES Cyber Systems (CIP-003-6, Requirement R1, 
Part 1.2 and Requirement R2) until April 1, 2017.\89\
---------------------------------------------------------------------------

    \89\ Id. at 53-54.
---------------------------------------------------------------------------

    72. NERC's proposed implementation plan also includes effective 
dates for the new and modified definitions associated with: (1) 
transient devices (i.e., BES Cyber Asset, Protected Cyber Asset, 
Removable Media, and Transient Cyber Asset); and (2) Low Impact 
controls (i.e., Low Impact Electronic Access Point and Low Impact 
External Routable Connectivity). Specifically, NERC proposes: (1) That 
the definitions associated with transient device become effective on 
the compliance date for Reliability Standard CIP-010-2, Requirement R4; 
and (2) that the definitions addressing the Low Impact controls become 
enforceable on the compliance date for Reliability Standard CIP-003-6, 
Requirement R2. Lastly, NERC proposes that the retirement of 
Reliability Standards CIP-003-5, CIP-004-5.1, CIP-006-5, CIP-007-5, 
CIP-009-5, CIP-010-1 and CIP-011-1 become effective on the effective 
date of the proposed Reliability Standards.\90\
---------------------------------------------------------------------------

    \90\ Id. at 56.
---------------------------------------------------------------------------

    73. We propose to approve NERC's implementation plan for the 
proposed CIP Reliability Standards, as described above.

H. Violation Risk Factor/Violation Severity Level Assignments

    74. NERC requests approval of the violation risk factors and 
violation severity levels assigned to the proposed Reliability 
Standards. Specifically, NERC requests approval of 19 violation risk 
factor and violation severity level assignments associated with the 
proposed Reliability Standards.\91\ We propose to accept these 
violation risk factors and violation severity levels.
---------------------------------------------------------------------------

    \91\ Id., Exhibit E.
---------------------------------------------------------------------------

III. Information Collection Statement

    75. The FERC-725B information collection requirements contained in 
this Proposed Rule are subject to review by the Office of Management 
and Budget (OMB) under section 3507(d) of the Paperwork Reduction Act 
of 1995.\92\ OMB's regulations require approval of certain information 
collection requirements imposed by agency rules.\93\ Upon approval of a 
collection of information, OMB will assign an OMB control number and 
expiration date. Respondents subject to the filing requirements of this 
rule will not be penalized for failing to respond to these collections 
of information unless the collections of information display a valid 
OMB control number. The Commission solicits comments on the 
Commission's need for this information, whether the information will 
have practical utility, the accuracy of the burden estimates, ways to 
enhance the quality, utility, and clarity of the information to be 
collected or retained, and any suggested methods for minimizing 
respondents' burden, including the use of automated information 
techniques.
---------------------------------------------------------------------------

    \92\ 44 U.S.C. 3507(d).
    \93\ 5 CFR 1320.11 (2012).
---------------------------------------------------------------------------

    76. The Commission based its paperwork burden estimates on the 
changes in paperwork burden presented by the proposed CIP Reliability 
Standards as compared to the CIP version 5 Standards. The Commission 
has already addressed the burden of implementing the CIP version 5 
Standards.\94\ As discussed above, the immediate rulemaking addresses 
four areas of modification to the CIP standards: (1) Removal of the 
``identify.

[[Page 43365]]

assess, and correct'' language from 17 CIP requirements; (2) 
development of enhanced security controls for low impact assets; (3) 
development of controls to protect transient devices (e.g. thumb drives 
and laptop computers); and (4) protection of communications networks. 
We do not anticipate that the removal of the ``identify, assess and 
correct'' language will impact the reporting burden, as the substantive 
compliance requirements would remain the same, while NERC indicates 
that the concept behind the deleted language continues to be 
implemented within NERC's compliance function. The development of 
controls to protect transient devices and protection of communication 
networks (as proposed by NERC) have associated reporting burdens that 
will affect a limited number of entities, i.e., those with Medium and 
High Impact BES Cyber Systems. The enhanced security controls for Low 
Impact assets are likely to impose a reporting burden on a much larger 
group of entities.
---------------------------------------------------------------------------

    \94\ See Order No. 791, 145 FERC ] 61,160 at PP 226-244.
---------------------------------------------------------------------------

    77. The NERC Compliance Registry, as of June 2015, identifies 
approximately 1,435 U.S. entities that are subject to mandatory 
compliance with Reliability Standards. Of this total, we estimate that 
1,363 entities will face an increased paperwork burden under the 
proposed CIP Reliability Standards, and we estimate that a majority of 
these entities will have one or more Low Impact assets. In addition, we 
estimate that approximately 23 percent of the entities have assets that 
will be subject to Reliability Standards CIP-006-6 and CIP-010-2. Based 
on these assumptions, we estimate the following reporting burden:

----------------------------------------------------------------------------------------------------------------
                                                                   Total burden    Total burden    Total burden

    Totals......................................             313          75,120         130,208         130,208
----------------------------------------------------------------------------------------------------------------

    78. The following shows the annual cost burden for each group, 
based on the burden hours in the table above:
     Year 1: Entities subject to CIP-006-6 and CIP-010-2 with 
Medium and/or High Impact Assets: 313 x 240 hours/entity * $76/hour = 
$5,709,120.
     Years 2 and 3: 313 entities x 416 hours/entity * $76/hour 
= $9,895,808 per year.
     The paperwork burden estimate includes costs associated 
with the initial development of a policy to address requirements 
relating to transient devices, as well as the ongoing data collection 
burden. Further, the estimate reflects the assumption that costs 
incurred in year 1 will pertain to policy development, while costs in 
years 2 and 3 will reflect the burden associated with maintaining logs 
and other records to demonstrate ongoing compliance.

----------------------------------------------------------------------------------------------------------------
                                                                   Total burden    Total burden    Total burden

----------------------------------------------------------------------------------------------------------------

    79. The following shows the annual cost burden for each group, 
based on the burden hours in the table above:
     Year 1: Entities subject to CIP-003-6 with Low Impact 
Assets: 1,363 x 120 hours/entity * $76/hour = $12,430,560.
     Years 2 and 3: 1,363 entities x 208 hours/entity * $76/
hour = $21,546,304 per year.
     The paperwork burden estimate includes costs associated 
with the modification of existing policies to address requirements 
relating to low impact assets, as well as the ongoing data collection 
burden, as set forth in CIP-003-6, Requirements R1.2 and R2, and 
Attachment 1. Further, the estimate reflects the assumption that costs 
incurred in year 1 will pertain to revising existing policies, while 
costs in years 2 and 3 will reflect the burden associated with 
maintaining logs and other records to demonstrate ongoing compliance.
    80. The estimated hourly rate of $76 is the average loaded cost 
(wage plus benefits) of legal services ($129.68 per hour), technical 
employees ($58.17 per hour) and administrative support ($39.12 per 
hour), based on hourly rates and average benefits data from the Bureau 
of Labor Statistics.\95\

IV. Regulatory Flexibility Act Analysis

    84. The Regulatory Flexibility Act of 1980 (RFA) generally requires 
a description and analysis of Proposed Rules that will have significant 
economic impact on a substantial number of small entities.\96\ The 
Small Business Administration's (SBA) Office of Size Standards develops 
the numerical definition of a small business.\97\ The SBA revised its 
size standard for electric utilities (effective January 22, 2014) to a 
standard based on the number of employees, including affiliates (from 
the prior standard based on megawatt hour sales).\98\ Proposed 
Reliability Standards CIP-003-6, CIP-004-6, CIP-006-6, CIP-007-6, CIP-
009-6, CIP-010-2, and CIP-011-2 are expected to impose an additional 
burden on 1,363 entities \99\ (reliability coordinators, generator 
operators, generator owners, interchange coordinators or authorities, 
transmission operators, balancing authorities, transmission owners, and 
certain distribution providers).
---------------------------------------------------------------------------

    \96\ 5 U.S.C. 601-12.
    \97\ 13 CFR 121.101 (2013).
    \98\ SBA Final Rule on ``Small Business Size Standards: 
Utilities,'' 78 FR 77343 (Dec. 23, 2013).
    \99\ Public utilities may fall under one of several different 
categories, each with a size threshold based on the company's number 
of employees, including affiliates, the parent company, and 
subsidiaries. For the analysis in this NOPR, we are using a 500 
employee threshold for each affected entity to conduct a 
comprehensive analysis.
---------------------------------------------------------------------------

    85. Of the 1,363 affected entities discussed above, we estimate 
that 444 entities are small entities. We estimate that 399 of these 444 
small entities do not own BES Cyber Assets or BES Cyber Systems that 
are classified as Medium or High Impact and, therefore, will only be 
affected by the proposed modifications to Reliability Standard CIP-003-
6. As discussed above, proposed Reliability Standard CIP-003-6 enhances 
reliability by providing criteria against which NERC and the Commission 
can evaluate the sufficiency of an entity's protections for Low Impact 
BES Cyber Assets. We estimate that each of the 399 small entities to 
whom the proposed modifications to Reliability Standard CIP-003-6 
applies will incur one-time costs of approximately $149,358 per entity 
to implement this standard, as well as the ongoing paperwork burden 
reflected in the Information Collection Statement (approximately 
$15,000 per year per entity). We do not consider the estimated costs 
for these 399 small entities a significant economic impact.
    86. In addition, we estimate that 14 small entities own Medium 
Impact substations and that 31 small transmission operators own Medium 
or High impact control centers. These 45 small entities represent 10.1 
percent of the 444 affected small entities. We estimate that each of 
these 45 small entities may experience an economic impact of $50,000 
per entity in the first year of initial implementation to meet proposed 
Reliability Standard CIP-010-2 and $30,000 in ongoing annual 
costs,\100\ for a total of $110,000 per entity over the first three 
years. Therefore, we estimate that each of these 45 small entities will 
incur a total of $258,654 in costs over the first three years. We 
conclude that 10.1 percent of the total 444 affected small entities 
does not represent a substantial number in terms of the total number of 
regulated small entities.

    \100\ Estimated annual cost for year 2 and forward.
---------------------------------------------------------------------------

    87. Based on the above analysis, we propose to certify that the 
proposed Reliability Standards will not have a significant economic 
impact on a substantial number of small entities.

V. Environmental Analysis

    88. The Commission is required to prepare an Environmental 
Assessment or an Environmental Impact Statement for any action that may 
have a significant adverse effect on the human environment.\101\ The 
Commission has categorically excluded certain actions from this 
requirement as not having a significant effect on the human 
environment. Included in the exclusion are rules that are clarifying, 
corrective, or procedural or that do not substantially change the 
effect of the regulations being amended.\102\ The actions proposed 
herein fall within this categorical exclusion in the Commission's 
regulations.
