SUPPLEMENTARY INFORMATION:

I. Introduction

    The U.S. Nuclear Regulatory Commission (NRC or Commission) is 
issuing a new guide in the agency's ``Regulatory Guide'' series. This 
series was developed to describe and make available to the public 
information such as methods that are acceptable to the NRC staff for 
implementing specific parts of the agency's regulations, techniques 
that the staff uses in evaluating specific problems or postulated 
accidents, and data that the staff needs in its review of applications 
for permits and licenses.
    RG 5.71, ``Cyber Security Programs for Nuclear Facilities,'' was 
issued with a temporary identification as Draft Regulatory Guide, DG-
5022. This regulatory guide provides guidance to applicants and 
licensees on satisfying the requirements of 10 CFR 73.54. The 
information contained within this guide represents the results of 
research conducted by the NRC Office of Nuclear Regulatory Research 
concerning cyber security program development and the collective body 
of knowledge and experience that has been developed through all of the 
actions identified above. In addition, this guide embodies the findings 
by standards organizations and agencies, such as the International 
Society of Automation, the Institute of Electrical and Electronic 
Engineers, and the National Institute of Standard and Technology, as 
well as guidance from the U.S. Department of Homeland Security.
    RG 5.71 provides a framework to aid in the identification of those 
digital assets that must be protected from cyber attacks. These 
identified digital assets are referred to as critical digital assets 
(CDAs). Licensees should address the potential cyber security risks of 
CDAs by applying the defensive architecture and the collection of 
security controls identified in this regulatory guide.
    The RG 5.71 framework offers licensees and applicants the ability 
to address the specific needs of an existing or new system. The goal of 
this regulatory guide is to harmonize the well-known and well-
understood set of security controls (based on NIST cyber security 
standards) that address potential cyber risks to CDAs to provide a 
flexible programmatic approach in which the licensee or applicant can 
establish, maintain, and successfully integrate these security controls 
into a site-specific cyber security program.

II. Further Information

    The Agency released DG-5022, which contained safeguards 
information, directly to stakeholders, who provided comments on July
