Furthermore, 10 CFR 73.54(e)(2)(i) requires licensees to maintain a cyber security plan that describes how the licensee will maintain the capability for timely detection and response to cyber attacks. The ability for a licensee to detect and respond to cyber attacks requires accurate and complete records and is further supported by 10 CFR 73.54(h), which states that the licensee shall retain all records and supporting technical documentation required to satisfy the requirements of 10 CFR Section 73.54 as a record until the Commission terminates the license for which the records were developed, and shall maintain superseded portions of these records for at least 3 years after the record is superseded, unless otherwise specified by the Commission. | |||
The licensee's Cyber Security Plan (CSP) in Section 4.13 states that Critical Digital Asset (CDA) audit records and audit data (e.g., operating system logs, network device logs) are retained for a period of time that is less than what is required by 10 CFR 73.54(h). | |||
Explain the deviation from the 10 CFR 73.54(h) requirement to retain records and supporting technical documentation until the Commission terminates the license (or to maintain superseded portions of these records for at least 3 years) and how that meets the requirements of 10 CFR 73.54. RAI 1 Response: | |||
Enclosure 2 provides a revised Section 4.13 to the Fermi 2 Cyber Security Plan. This enclosure replaces the text in Section 4.13 of Reference 2, in its entirety. | |||
The proposed revised records retention wording is consistent with the wording provided by NEI to the NRC on February 28, 2011. RAI 2: Implementation Schedule The regulation at 10 CFR 73.54, "Protection of digital computer and communication systems and networks," requires licensees to submit a CSP that satisfies the requirements of this section for Commission review and approval. | |||
Furthermore, each submittal must include a proposed implementation schedule and the implementation of the licensee's cyber security program must be consistent with the approved schedule. | |||
Paragraph 73.54(a) of 10 CFR requires licensees to provide high assurance that digital computer and communication systems and networks are adequately protected against cyber attacks, up to and including the design basis threat. Enclosure 3 contains Security Related Information | |||

The Nuclear Regulatory Commission (NRC) staffs expectation is that the key intermediate milestones will be completed in a timely manner, but no later than December 31,2012. The key CSP implementation milestones are as follows: Establish, train and qualify Cyber Security Assessment Team, as described in Section 3.1.2, "Cyber Security Assessment Team," of the CSP. Identify Critical Systems and CD As, as described in Section 3.1.3, "Identification of Critical Digital Assets," of the CSP. Implement cyber security in-depth architecture by installation of [deterministic devices], as described in Section 4.3, Protective Strategies" of the CSP. d) Implement the management, operational and technical cyber security controls that address attacks promulgated by use of portable media, portable devices, and portable equipment as described in Appendix D Section 1.19 "Access Control for Portable and Mobile Devices," of Nuclear Energy Institute (NEI) 08-09, Revision 6. Implement observation and identification of obvious cyber related tampering to existing insider mitigation rounds as described in Appendix E Section 4.3, "Personnel Performing Maintenance and Testing Activities," and Appendix E Section 10.3, "Baseline Configuration" ofNEI 08-09, Revision 6. Identify, document, and implement cyber security controls to physical security target set CDAs in accordance with Section 3.1.6, "Mitigation of Vulnerabilities and Application of Cyber Security Controls," of the CSP. Ongoing monitoring and assessment activities will commence for those target set CDAs whose security controls have been implemented, as described in Section 4.4, "Ongoing Monitoring and Assessment," of the CSP.

Scope and Purpose This Plan establishes a means to achieve high assurance that digital computer and communication systems and networks associated with the following functions (hereafter designated as Critical Digital Assets (CDAs)) are adequately protected against cyber attacks up to and including the Design Basis Threat (DBT) as described in 10 CFR 73.1: Safety-related and important-to safety functions; Security functions; Emergency preparedness functions including offsite communications; and Support systems and equipment which if compromised, would adversely impact safety, security, or emergency preparedness functions. | |||
The safety-related and important-to safety functions, security functions, and emergency preparedness functions including off site communications are herein referred to as SSEP functions. | |||
Within the scope of NRC's cyber security rule at Title 10 of the Code of Federal Regulations (10 CFR) 73.54, systems or equipment that perform important to safety functions include structures, systems, and components (SSCs) in the balance of plant (BOP) that could directly or indirectly affect reactivity at a nuclear power plant and could result in an unplanned reactor shutdown or transient. | |||
Additionally, these SSCs are under Detroit Edison's control and include electrical distribution equipment out to the first inter-tie with the offsite distribution system. High assurance of adequate protection of systems associated with the above functions from cyber attacks is achieved by: Implementing and documenting the "baseline" cyber security controls described in Section 3.1.6 of this Plan; and Implementing and documenting a cyber security program to maintain the established cyber security controls through a comprehensive life cycle approach as described in Section 4 of this Plan.

Events identified for auditing are recorded in accordance with Appendix D, Section 2.3, Content of Audible Events and Appendix D, Section 2.4, Audit Storage Capacity (for electronic audit records).
The source of audit able events (electronic and electronic) include, but are not limited to: Operating system logs Service and application logs Network device logs Access Logs Audit records of auditable events are retained to document access history, as well as to discover the source of cyber attacks or other security-related incidents affecting CDAs or SSEP functions, or both. These records are reviewed and analyzed in accordance with procedures implementing NEI 09, Revision 6, Appendix D, Section 2.6, Audit Review, Analysis and Reporting.
The review and analysis is conducted consistent with maintaining high assurance that digital computer and communication systems and networks are adequately protected against cyber attacks, up to and including the design basis threat as described in 10 CFR 73.1. Superseded records (or portions thereof) are then retained for three years, after the record has been reviewed and analyzed.

Scope and Purpose This Plan establishes a means to achieve high assurance that digital computer and communication systems and networks associated with the following functions (hereafter designated as Critical Digital Assets (CDAs)) are adequately protected against cyber attacks up to and including the Design Basis Threat (DBT) as described in 10 CFR 73.1: Safety-related and important-to safety functions; Security functions; Emergency preparedness functions including offsite communications; and Support systems and equipment which if compromised, would adversely impact safety, security, or emergency preparedness functions.
The safety-related and important-to safety functions, security functions, and emergency preparedness functions including off site communications are herein referred to as SSEP functions.
Within the scope of NRC's cyber security rule at Title 10 of the Code of Federal Regulations (10 CFR) 73.54, systems or equipment that perform important to safety functions include structures, systems, and components (SSCs) in the balance of plant (BOP) that could directly or indirectly affect reactivity at a nuclear power plant and could result in an unplanned reactor shutdown or transient.
Additionally, these SSCs are under Detroit Edison's control and include electrical distribution equipment out to the first inter-tie with the offsite distribution system. High assurance of adequate protection of systems associated with the above functions from cyber attacks is achieved by: Implementing and documenting the "baseline" cyber security controls described in Section 3.1.6 of this Plan; and Implementing and documenting a cyber security program to maintain the established cyber security controls through a comprehensive life cycle approach as described in Section 4 of this Plan.
