PRIVACY IMPACT ASSESSMENT (PIA)

PRESCRIBING AUTHORITY: DoD Instruction 5400.16, "DoD Privacy Impact Assessment (PIA) Guidance". Complete this form for Department of Defense

(DoD) information systems or electronic collections of information (referred to as an "electronic collection" for the purpose of this form) that collect, maintain, use,

and/or disseminate personally identifiable information (PII) about members of the public, Federal employees, contractors, or foreign nationals employed at U.S.

military facilities internationally. In the case where no PII is collected, the PIA will serve as a conclusive determination that privacy requirements do not apply to

system.

New DoD Information System New Electronic Collection

Existing DoD Information System Existing Electronic Collection

Significantly Modified DoD Information System

c. Describe the purpose of this DoD information system or electronic collection and describe the types of personal information about individuals

collected in the system.

Acropolis is an "Enclave" baseline configured, fielded, and sustained by DISA Infrastructure Development ID66. Acropolis enables global

Computer Network Defense (CND) to achieve increased protection, more productivity, and greater visibility. By delivering a single point of

data aggregation, real-time analysis, incident investigation and reporting, Acropolis provides a coordinated infrastructure that maximizes

asset protection while decreasing overall costs. Acropolis provides a comprehensive security management environment, featuring the

following: a centralized repository of cyber security events generated by sensors throughout the Department of Defense Information Network

(DoDIN), real-time filtering and correlation of gathered data, automated security event investigation, and comprehensive reporting.

Data collected for each user includes:

Names(s), Other ID number, DoD ID number, Official Duty Telephone Phone, Official Duty Address, Citizenship and other (Branch of

Service, Agency, Enterprise Email Address).

d. Why is the PII collected and/or what is the intended use of the PII? (e.g., verification, identification, authentication, data matching, mission-related use,

administrative use)

The system will be used to correlate user activities across a variety of cybersecurity-related records for the purpose of attack detection and

insider threat analysis. In particular, the information system makes it possible to relate records containing various user identifiers (i.e. email

addresses, DoD ID, name, etc...) to one another for the purpose of tracking a user's activities across multiple, disjoint systems.

e. Do individuals have the opportunity to object to the collection of their PII? Yes No

(1) If "Yes," describe the method by which individuals can object to the collection of PII.

(2) If "No," state the reason why individuals cannot object to the collection of PII.

Individuals can object to the collection of their PII by not completing and submitting the information required.

f. Do individuals have the opportunity to consent to the specific uses of their PII? Yes No

(1) If "Yes," describe the method by which individuals can give or withhold their consent.

(2) If "No," state the reason why individuals cannot give or withhold their consent.

Individuals can object to the specific uses of their PII by not completing and submitting the information required.

g. When an individual is asked to provide PII, a Privacy Act Statement (PAS) and/or a Privacy Advisory must be provided. (Check as appropriate and

provide the actual wording.)

k. Does this DoD Information system or electronic collection require a Privacy Act System of Records Notice (SORN)?

A Privacy Act SORN is required if the information system or electronic collection contains information about U.S. citizens or lawful permanent U.S. residents that

is retrieved by name or other unique identifier. PIA and Privacy Act SORN information must be consistent.

Yes No

If "Yes," enter SORN System Identifier K890.15 DoD

SORN Identifier, not the Federal Register (FR) Citation. Consult the DoD Component Privacy Office for additional information or http://dpcld.defense.gov/

Privacy/SORNs/

or

If a SORN has not yet been published in the Federal Register, enter date of submission for approval to Defense Privacy, Civil Liberties, and Transparency

Division (DPCLTD). Consult the DoD Component Privacy Office for this date

m. What is the authority to collect information? A Federal law or Executive Order must authorize the collection and maintenance of a system of

records. For PII not collected or maintained in a system of records, the collection or maintenance of the PII must be necessary to discharge the

requirements of a statue or Executive Order.

(c) If direct or indirect authority does not exist, DoD Components can use their general statutory grants of authority (“internal housekeeping”) as

the primary authority. The requirement, directive, or instruction implementing the statute within the DoD Component must be identified.
