DAVIS-BESSE NUCLEAR POWER STATION, UNIT NO.1 DOCKET NO. 50-346

1.0 INTRODUCTION

By letter dated July 16, 2010 (Agencywide Documents Access and Management System (ADAMS) Accession No.1 02020203), as supplemented by letters dated September 28,2010, November 23,2010, February 1, 2011, and April 8, 2011 (ADAMS) Accession Nos.

ML102740569, ML103350171 , ML110390058, and ML11103A035, respectively), FirstEnergy Nuclear Operating Company (FENOC, the licensee) requested changes to the facility operating licenses for the Davis-Besse Nuclear Power Plant (DBNPS), Unit NO.1. Included in that license amendment request was a request for approval of the licensee's Cyber Security Plan (CSP) and Implementation Schedule for DBNPS, Unit 1, as required by Section 73.54, "Protection of Digital Computer and Communication Systems and Networks," of Title 10 of the Code of Federal Regulations (10 CFR). The U.S. Nuclear Regulatory Commission (NRC, the Commission) staff provided the licensee with requests for additional information (RAls) regarding the staffs concerns with the CSP. On April 8, 2011, the licensee supplemented its CSP, to address: (1) scope of systems in response to the October 21,2010, Commission decision (Reference 1);

(2) records retention; and (3) implementation schedule. The licensee submitted a Revision 0 of the CSP incorporating all of the changes and/or additional information. Portions of the letter dated July 16, 2010, and the entire letter dated April 8, 2011, contain sensitive unclassified non safeguards information (security-related) and, accordingly, are being withheld from public disclosure.

The supplements dated September 28, 2010, November 23, 2010, February 1, 2011, and April 8, 2011, provided additional information that clarified the application, and did not expand the scope of application as originally noticed, and did not change the NRC staffs initial proposed finding of no significant hazards consideration as published in the Federal Register on February 1, 2011 (76 FR 5621).

The amendment would approve the CSP and associated implementation schedule, and revise Paragraph 2.D of Facility Operating License (FOL) No. NPF-3 for DBNPS, to provide a license condition to require the licensee to fully implement and maintain in effect all provisions of the NRC-approved CSP. The proposed change is generally consistent with the Nuclear Energy Institute (NEI) 08-09, Revision 6, "Cyber Security Plan for Nuclear Power Plants."

2.0 REGULATORY EVALUATION

2.1 General Requirements Consistent with 10 CFR 73.54(a), the licensee must 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 (DBT), as described in 10 CFR 73.1. The licensee shall protect digital computer and communication systems and networks associated with: (i) safety related and important-to-safety functions; (ii) security functions; (iii) emergency preparedness functions, including offsite communications; and (iv) support systems and equipment which, if compromised, would adversely impact safety, security, or emergency preparedness (SSEP) functions. The rule specifies that digital computer and communication systems and networks associated with these functions must be protected from cyber attacks that would adversely impact the integrity or confidentiality of data and software; deny access to systems, services, or data; or provide an adverse impact to the operations of systems, networks, and associated equipment.

In the Staff Requirements Memorandum (SRM) COMWCO-10-0001, "Regulation of Cyber Security at Nuclear Power Plants," dated October 21, 2010 (Reference 1), the Commission stated that the NRC's cyber security rule at 10 CFR 73.54 should be interpreted to include structures, systems, and components (SSCs) in the balance of plant (BOP) that have a nexus to radiological health and safety. The NRC staff determined that SSCs in the BOP that have a nexus to radiological health and safety are those that could directly or indirectly affect reactivity of a nuclear power plant (NPP), and are therefore within the scope of important-to-safety functions described in 10 CFR 73.54(a)(1).

2.2 Elements of a CSP As stated in 10 CFR 73.54(e), the licensee must establish, implement, and maintain a CSP that satisfies the Cyber Security Program requirements of this regulation. In addition, a CSP must describe how the licensee will implement the requirements of the regulation and must account for the site-specific conditions that affect implementation. One method of complying with this regulation is to describe within the CSP how the licensee will achieve high assurance that all SSEP functions are protected from cyber attacks.

2.3 Regulatorv Guide (RG) 5.71 and Nuclear Energy Institute (NEil OS-09, Revision 6 NRC-developed RG 5.71, "Cyber Security Programs for Nuclear Facilities" (ADAMS Accession No. ML090340159), describes a regulatory position that promotes a defensive strategy consisting of a defensive architecture and a set of security controls based on standards provided in the National Institute of Standards and Technology (NIST) Special Publication (SP) SOO-53, "Recommended Security Controls for Federal Information Systems and Organizations" and NIST SP SOO-S2, "Guide to Industrial Control Systems Security," dated September 29, 200S.

NIST SP SOO-53 and NIST SP SOO-S2 are based on well-understood cyber threats, risks, and vulnerabilities, coupled with equally well-understood countermeasures and protective techniques. RG 5.71 divides the above-noted security controls into three broad categories:

technical, operational, and management. The RG 5.71 provides a framework to aid in the identification of those digital assets that licensees must protect from cyber attacks. These

-3 identified digital assets are referred to as critical digital assets (CDAs). Licensees should address the potential cyber security risks to CDAs by applying the defensive architecture and addressing the collection of security controls identified in RG 5.71. RG 5.71 includes a CSP template that provides one method for preparing an acceptable CSP.

The organization of RG 5.71 reflects the steps necessary to meet the requirements of 10 CFR 73.54, Section C.3 of RG 5.71 describes an acceptable method for implementing the security controls, as detailed in Appendix B, "Technical Controls," and Appendix C, "Operational and Management Controls." Section C.4 of RG 5.71 discusses the need to maintain the established Cyber Security Program, including comprehensive monitoring of the CDAs and the effectiveness of their security protection measures, ensuring that changes to the CDAs or the environment are controlled, coordinated, and periodically reviewed for continued protection from cyber attacks.

Section C.5 of RG 5.71 provides licensees and applicants with guidance for retaining records associated with their cyber security programs. Appendix A to RG 5.71 provides a template for a generic cyber security plan which licensees may use to comply with the licensing requirements of 10 CFR 73.54. Appendices Band C provide an acceptable set of security controls, which are based on well-understood threats, vulnerabilities, and attacks, coupled with equally well understood and vetted countermeasures and protective techniques.

In NEI 08-09, Revision 6, it closely maps with RG 5.71; Appendix A, of NEI 08-09, Revision 6 contains a CSP template that is comparable to Appendix A of RG 5.71.

Appendix D of NEI 08-09, Revision 6, contains technical cyber security controls that are comparable to Appendix B of RG 5.71. Appendix E of NEI 08-09, Revision 6, contains operational and management cyber security controls that are comparable to Appendix C of RG 5.71.

In its letter to NEI dated May 5,2010 (Reference 3), the NRC stated that the licensees may use the template in NEI 08-09, Revision 6 (Reference 4), to prepare an acceptable CSP, with the exception of the definition of "cyber attack." The NRC staff subsequently reviewed and approved by letter dated June 7,2010 (Reference 5), a definition for "cyber attack" to be used in submissions based on NEI 08-09, Revision 6. The licensee submitted a CSP for the DBNPS, Units 1, that was based on the template provided in NEI 08-09. Revision 6, and included a definition of cyber attack acceptable to the NRC staff in the deviation table in Enclosure 3 of the CSP submitted by the licensee. Additionally, the licensee submitted a supplement to its CSP on September 28.2010, to include information on SSCs in the BOP that, if compromised, could affect NPP reactivity.

The RG 5.71 and NEI 08-09, Revision 6, are comparable documents; both are based on essentially the same general approach and same set of technical, operational, and management security controls. The CSP submitted by the licensee was reviewed against the corresponding sections in RG 5.71.

3.0 TECHNICAL EVALUATION

The NRC staff performed a technical evaluation of the licensee's submittal. The licensee's submittal, with the exception of deviations described in Section 4.0 of this safety evaluation (SE),

generally conformed to the guidance in NEI 08-09, Revision 6, which was found to be acceptable by the NRC staff and comparable to RG 5.71 to satisfy the requirements contained in 10 CFR 73.54. The NRC staff reviewed the licensee's submittal against the requirements of

-4 10 CFR 73.54 following the guidance contained in RG 5.71. The NRC staff evaluation of each section of the licensee's submittal is discussed below.

3.1 Scope and Purpose The licensee's CSP establishes a means to achieve high assurance that digital computer and communication systems and networks associated with the following functions are adequately protected against cyber attacks up to and including the DBT:

  • Safety-related and important-to-safety functions;
  • Security functions;
  • Support systems and equipment which, if compromised, would adversely impact SSEP functions.

The licensee's CSP describes achievement of high assurance of adequate protection of systems associated with the above functions from cyber attacks by implementing and documenting:

  • The baseline security controls as described in Section 3.1.6 of NEI 08-09, Revision 6, which is comparable to Regulatory Position C.3.3 described in RG 5.71; and
  • A Cyber Security Program to maintain the established cyber security controls through a comprehensive life cycle approach as described in Section 4 of NEI 08-09, Revision 6, which is comparable to Section A.2.1 of RG 5.71.

Thus, the licensee's CSP, as originally submitted, is comparable to the CSP in NEI 08-09, Revision 6. However, in its submittal dated April 8, 2011, the licensee clarified its original submission and indicated that the scope of systems includes those BOP SSCs that have an impact on NPP reactivity if compromised. This is in response to and consistent with SRM-COMWCO-10-0001, in which the Commission stated that the NRC's cyber security rule provided in 10 CFR 73.54 should be interpreted to include SSCs in the BOP that have a nexus to radiological health and safety. The NRC staff determined that this is defined as those systems that have a nexus to radiological health and safety are those that could directly or indirectly affect reactivity of a NPP, and are therefore within the scope of important-to-safety functions described in 10 CFR 73.54(a)(1).

The NRC staff reviewed the CSP and the supplemental information submitted by the licensee and found no deviation from Regulatory Position C.3.3 in RG 5.71 and Appendix A, Section A.2.1 of RG 5.71. The NRC staff finds that the licensee established adequate measures to implement and document the Cyber Security Program, including baseline security controls.

-5 Based on the above, the NRC staff finds that the DBNPS CSP adequately establishes the Cyber Security Program, including baseline security controls.

3.2 Analyzing Digital Computer Systems and Networks and Applying Cyber Security Controls The licensee's CSP describes that the Cyber Security Program is established, implemented, and maintained as described in Section 3.1 of NEI 08-09, Revision 6, which is comparable to Regulatory Position C.3.1 described in RG 5.71 to:

  • Analyze digital computer and communications systems and networks; and

The licensee's CSP describes how the cyber security controls in Appendices D and E of NEI 08-09, Revision 6, which are comparable to Appendices Band C in RG 5.71, are addressed to protect CDAs from cyber attacks.

This section of the CSP submitted by the licensee is comparable to Regulatory Position C.3.1 in RG 5.71, without deviation.

Based on the above, the NRC staff finds that the CSP adequately addresses security controls.

3.3 Cyber Security Assessment and Authorization The licensee provided information addressing the creation of a formal, documented, cyber security assessment and authorization policy. This included a description concerning the creation of a formal, documented procedure comparable to Section 3.1.1 of NEI 08-09, Revision 6.

The NRC staff finds that the licensee established adequate measures to define and address the purpose, scope, roles, responsibilities, management commitment, and coordination, and facilitates the implementation of the cyber security assessment and authorization policy.

The NRC staff reviewed the above information and found no deviation from Section 3.1.1 of NEI 08-09, Revision 6, which is comparable to Regulatory Position C.3.1.1 and Appendix A, Section A.3.1.1 of RG 5.71.

Based on the above, the NRC staff finds that the CSP adequately established controls to develop, disseminate, and periodically update the cyber security assessment and authorization policy and implementing procedure.

3.4 Cyber Security Assessment Team (CSAT)

The CSAT responsibilities include conducting the cyber security assessment, documenting key findings during the assessment, and evaluating assumptions and conclusions about cyber security threats. The licensee's CSP outlines the requirements, roles and responsibilities of the CSAT comparable to Section 3.1.2 of NEI 08-09, Revision 6. It also describes that the CSAT has the authority to conduct an independent assessment.

- 6 The licensee's CSP describes that the CSAT will consist of individuals with knowledge about information and digital systems technology; NPP operations, engineering, and plant technical specifications; and physical security and emergency preparedness systems and programs. The CSAT description in the CSP is comparable to Regulatory Position C.3.1.2 in RG 5.71.

The licensee's CSP lists the roles and responsibilities for the CSAT which included performing and overseeing the cyber security assessment process; documenting key observations; evaluating information about cyber security threats and vulnerabilities; confirming information obtained during tabletop reviews, walk-downs, or electronic validation of CDAs; and identifying potential new cyber security controls.

The licensee's CSP noted in the ninth bullet in Section 3.1.2 that the CSAT would be involved in "reviewing and approving" cyber security controls; this is a deviation from the NEI 08-09, Revision 6, specification, which states the CSAT would be responsible for "documenting" cyber security controls. The NRC staff requested clarification on how the controls would be documented. The licensee responded by stating that the documentation of controls would be ensured by a Cyber Security Specialist, but the preparation of the documentation could be accomplished by personnel from engineering, emergency preparedness, security or other disciplines, depending on the controls and the CDA under examination. The licensee submitted an updated CSP, and addressed the concern by inserting language in Section 3.1.6, "Mitigation and Vulnerabilities and Application of Cyber Security Controls," that "other plant organizations may be used to document the assessments." The updated CSP notes in the same section that the CSAT would review and approve the usage of each cyber security control. This language supports the licensee's assertion that the documentation of security controls will occur and that the CSAT will have the ultimate responsibility for ensuring this occurs.

This section of the CSP submitted by the licensee is comparable to Regulatory Position C.3.1.2 in RG 5.7.1.

Based on the CSP statement that cyber security controls will be documented by a Cyber Security Specialist and reviewed and approved by members of the CSAT, the NRC staff finds that the CSP adequately established the requirements, roles and responsibilities of the CSAT.

3.5 Identification of CDAs The licensee's CSP states that the licensee will identify and document CDAs and critical systems, including a general description, the overall function, the overall consequences if a compromise were to occur, and the security functional requirements or specifications as described in Section 3.1.3 of NEI 08-09, Revision 6, which is comparable to Regulatory Position C.3.1.3 of RG 5.71.

Based on the above, the NRC staff finds that the CSP adequately describes the process to identify CDAs.

3.6 Examination of Cyber Securitv Practices The licensee's CSP describes how the CSAT will examine and document the existing cyber security policies, procedures, and practices; existing cyber security controls; detailed descriptions of network and communication architectures (or network/communication architecture drawings); information on security devices; and any other information that may be

-7 helpful during the cyber security assessment process as described in, Section 3.1.4 of NEI 08-09, Revision 6, which is comparable to Regulatory Position C.3.1.2 of RG 5.71. The examinations will include an analysis of the effectiveness of the existing Cyber Security Program and cyber security controls. The CSAT will document the collected cyber security information and the results of their examination of the collected information. This section of the CSP submitted by the licensee is comparable to Regulatory Position C.3.1.2 in RG 5.71, without deviation.

Based on the above, the NRC staff finds that the CSP adequately describes the examination of cyber security practices.

3.7 Tabletop Reviews and Validation Testing The licensee's CSP describes tabletop reviews and validation testing, which confirm the direct and indirect connectivity of each COA and identify direct and indirect pathways to COAs. The CSP states that validation testing will be performed electronically or by physical walkdowns. The licensee's plan for tabletop reviews and validation testing is comparable to Section 3.1.5 of NEI 08-09, Revision 6, which is comparable to Regulatory Position C.3.1.4 of RG 5.71.

Based on the above, the NRC staff finds that the CSP adequately describes tabletop reviews and validation testing.

3.8 Mitigation of Vulnerabilities and Application of Cyber Securitv Controls The licensee's CSP describes the use of information collected during the cyber security assessment process (e.g., disposition of cyber security controls, defensive models, defensive strategy measures, site and corporate network architectures) to implement security controls in accordance with, Section 3.1.6 of NEI 08-09, Revision 6, which is comparable to Regulatory Position C.3.3 and Section A.3.1.6 to RG 5.71. The CSP describes the process that will be applied in cases where security controls cannot be implemented.

The licensee's CSP states that before the licensee can implement security controls on a COA, it will assess the potential for adverse impact in accordance with Appendix A, Section 3.1.6 of NEI 08-09, Revision 6, which is comparable to Regulatory Position C.3.3 of RG 5.71.

The licensee's CSP states that in the case of implementing alternative controls/

countermeasures that eliminate threat/attack vector(s) associated with one or more of the cyber security controls, that either an alternative countermeasure that provides at least the same degree of cyber security protection as the corresponding cyber security control will be implemented or an alternative frequency or periodicity for the security control will be implemented. The "or" condition in this statement is a deviation from NEI 08-09, Revision 6.

The NRC staff has reviewed this deviation and finds it to be acceptable on the basis that implementing alternative controls/countermeasures does not necessarily require an alternative frequency or periodicity be implemented.

Based on the NRC staff review of CSP statements that the licensee will implement cyber security controls, implement alternative controls/countermeasures, or not implement a control as per Section 3.1.6 of the licensee's CSP, the NRC staff finds that this section of the CSP

- 8 submitted by the licensee is comparable to Regulatory Position C.3.3 and Section A.3.1.6 of RG 5.71. The NRC staff also finds that this section of the CPS adequately describes mitigation of vulnerabilities and application of security controls.

3.9 Incorporating the Cyber Security Program into the Physical Protection Program The licensee's CSP states that the Cyber Security Program will be reviewed as a component of the Physical Security Program in accordance with the requirements of 10 CFR 73.55(m). This is comparable to Section 4.1 of NEI 08-09, Revision 6, which is comparable to Regulatory Position C.3.4 of RG 5.71.

This section of the CSP submitted by the licensee is comparable to Appendix A, Section A.3.2 in RG 5.71, without deviation.

Based on the above, the NRC staff finds that the CSP adequately describes review of the CSP as a component of the physical security program.

3.10 Cyber Security Controls The licensee's CSP describes how the technical, operational and management cyber security controls contained in Appendices D and E of NEI 08-09, Revision 6, that are comparable to Appendices Band C in RG 5.71, are evaluated and dispositioned based on site-specific conditions during all phases of the Cyber Security Program. The CSP describes that many security controls have actions that are required to be performed on specific frequencies and that the frequency of a security control is satisfied if the action is performed within 1.25 times the frequency specified in the control, as applied, and as measured from the previous performance of the action as described in Appendix A, Section 4.2 of NEI 08-09, Revision 6.

This section of the CSP submitted by the licensee is comparable to Section A.3.1.6 in RG 5.71, without deviation.

Based on the above, the NRC staff finds that the CSP adequately describes implementation of cyber security controls.

3.11 Defense-in-Depth Protective Strategies The submitted CSP describes the implementation of defensive strategies that ensure the capability to detect, respond to, and recover from a cyber attack. The CSP specifies that the defensive strategies consist of security controls, defense-in-depth measures, and the defensive architecture. The submitted CSP notes that the defensive architecture establishes the logical and physical boundaries to control the data transfer between these boundaries.

The licensee established defense-in-depth strategies by: implementing and documenting a defensive architecture as described in Section 4.3 of NEI 08-09, Revision 6, which is comparable to Regulatory Position C.3.2 in RG 5.71; a physical security program, including physical barriers; the operational and management controls described in Appendix E of NEI 08-09, Revision 6, which is comparable to Appendix C to RG 5.71; and the technical controls described in Appendix D of NEI 08-09, Revision 6, which is comparable to Appendix B to RG 5.71.

-9 In the revised CSP submitted on April 8, 2011 (ADAMS Accession No. ML111030065), the licensee stated that safety CDAs are in Level 4. This is consistent with RG 5.71, Section C.7 of Appendix C, which states that CDAs that carry out safety functions should be allocated the highest degree of protection (Le., Level 4); therefore, the NRC staff finds this clarification to be acceptable.

The licensee's CSP indicated that communications inherited from lower levels to CDAs at higher levels would be "(1) eliminated or (2) severely restricted." Since the protection and isolation of CDAs at higher levels of security is vital to those defense-in-depth strategies at power plants, the NRC staff requested clarification from the licensee on how communications inherited from lower defense levels would be "severely restricted." The licensee responded by letter dated February 1,2011 (ML110390057) that the DBNPS CSP would be revised to indicate

" ... communications from lower levels to CDAs at higher levels is eliminated." This is consistent with RG 5.71, Section C.7 of Appendix C, which states, "Initiation of communications from digital assets at lower security levels to digital assets at higher security levels is prohibited." Therefore, the NRC staff finds this clarification to be acceptable. This change was reflected in the updated CSP that was submitted on April 8, 2011 (ADAMS Accession No. ML111030065).

In the revised CSP submitted on April 8, 2011 (ADAMS Accession No. ML111030065), the licensee removed the site-specific description of the Defensive Architecture, including the phrase "data flows from one level to other levels only through a device or devices that enforces documented cyber security policy between levels and detects, prevents, or delays that mitigates, and recovers from cyber attacks coming from lower cyber security levels." The licensee revised the language to be identical with NEI 08-09, Revision 6, Section 4.3, Example 1, bullet 4.

Therefore, the NRC staff finds this clarification to be acceptable.

In the revised CSP submitted on April 8, 2011 (ADAMS Accession No. ML111030065), the licensee removed the phrase, "data transmission across defensive levels are analyzed, evaluated for risk, and protected." The defense-in-depth section was evaluated by NRC staff and found to be comparable to NEI 08-09, Revision 6, Section 4.3; therefore, it was found to be acceptable.

This section is comparable to Regulatory Position C.3.2 and Appendix A, Section A.3.1.5 in RG 5.71.

Based on the licensee's comprehensive defense-in-depth protective strategies providing the capability to detect, respond to, and recover from a cyber attack, the NRC staff finds that the CSP adequately describes implementation of defense-in-depth protective strategies.

3.12 Ongoing Monitoring and Assessment The licensee's CSP describes how ongoing monitoring of cyber security controls to support

  • CDAs is implemented as described in Appendix E of NEI 08-09, Revision 6, which is comparable to Regulatory Positions C.4.1 and C.4.2 of RG 5.71. The ongoing monitoring program includes configuration management and change control; cyber security impact analysis of changes and changed environments; ongoing assessments of cyber security controls; effectiveness analysis (to monitor and confirm that the cyber security controls are implemented

-10 correctly, operating as intended, and achieving the desired outcome) and vulnerability scans to identify new vulnerabilities that could affect the secUlity posture of CDAs.

This section of the CSP submitted by the licensee is comparable to Regulatory Positions C.4.1 and C.4.2 of RG 5.71, without deviation.

Based on the above, the NRC staff finds that the CSP adequately describes ongoing monitoring and assessment.

3.13 Modification of Digital Assets The licensee's CSP describes how cyber security controls are established, implemented, and maintained to protect CDAs. These security controls ensure that modifications to CDAs are evaluated before implementation that the cyber security performance objectives are maintained, and that acquired CDAs have cyber security requirements in place to achieve the site's Cyber Security Program objectives. This is comparable to Section 4.5 of NEI OB-09, Revision 6, which is comparable to Appendix A, Sections A.4.2.5 and A.4.2.6 of RG 5.71.

Based on the above, the NRC staff finds that the CSP adequately describes modification of digital assets.

3.14 Attack Mitigation and Incident Response The licensee's CSP describes the process to ensure that SSEP functions are not adversely impacted due to cyber attacks in accordance with Section 4.6 of NEI OB-09, Revision 6, which is comparable to Appendix C, Section C.B of RG 5.71. The CSP includes a discussion about creating incident response policy and procedures, addresses training, testing and drills, incident handling, incident monitoring, and incident response assistance. It also describes identification, detection, response, containment, eradication, and recovery activities comparable to Section 4.6 of NEI OB-09, Revision 6.

This section of the CSP submitted by the licensee is comparable to Appendix C, Section C.B, of RG 5.71, without deviation.

Based on the above, the NRC staff finds that the CSP adequately describes attack mitigation and incident response.

3.15 Cyber Security Contingency Plan The licensee submitted CSP describes creation of a Cyber Security Contingency Plan and policy that protects CDAs from the adverse impacts of a cyber attack described in Section 4.7 of NEI OB-09, Revision 6, which is comparable to Regulatory Position C.3.3.2.7 and Appendix C.9 of RG 5.71. The licensee describes the Cyber Security Contingency Plan that would include the response to events. The plan includes procedures for operating CDAs in a contingency, roles information, logical diagrams of network connectivity, current configuration information, and personnel lists for authorized access to CDA.

This section of the CSP submitted by the licensee is comparable to Regulatory Position C.3.3.2.7 of RG 5.71, without deviation.

- 11 Based on the above, the NRC staff finds that the CSP adequately describes the Cyber Security Contingency Plan.

3.16 Cyber Security Training and Awareness The licensee's CSP describes a program that establishes the training requirements necessary for the licensee's personnel and contractors to perform their assigned duties and responsibilities in implementing the Cyber Security Program in accordance with Section 4.8 of NEI 08-09, Revision 6, which is comparable to Regulatory Position C.3.3.2.8 of RG 5.71.

The CSP states that individuals will be trained with a level of cyber security knowledge commensurate with their assigned responsibilities in order to provide high assurance that individuals are able to perform their job functions in accordance with Appendix E of NEI 08-09, Revision 6, which is comparable to Regulatory Position C.3.3.2.8 of RG 5.71 and describes three levels of training: awareness training, technical training, and specialized cyber security training program.

Based on the above, the NRC staff finds that the CSP adequately describes the cyber security training and awareness program.

3.17 Evaluate and Manage Cyber Risk The CSP submitted by the licensee describes how cyber risk is evaluated and managed utilizing site programs and procedures comparable to Section 4.9 of NEI 08-09, Revision 6, which is comparable to Regulatory Position CA and Appendix C, Section C.13 of RG 5.71. The CSP describes the Threat and Vulnerability Management Program, Risk Mitigation, Operational Experience Programs, and the Corrective Action Program and how each will be used to evaluate and manage risk.

This section of the CSP submitted by the licensee is comparable to Regulatory Position CA and Appendix C, Section C.13 of RG 5.71, without deviation.

Based on the above, the NRC staff finds that the CSP adequately describes evaluation and management of cyber risk.

3.18 Policies and Implementing Procedures The CSP describes development and implementation of policies and procedures to meet security control objectives in accordance with Section 4.10 of NEI 08-09, Revision 6, which is comparable to Regulatory Position C.3.5 and Appendix A, Section A.3.3 of RG 5.71. This includes the process to document, review, approve, issue, use, and revise policies and procedures.

The CSP also describes the licensee's procedures to establish specific responsibilities for positions described in Appendix A, Section 4.11 of NEI 08-09, Revision 6, which is comparable to Appendix C, Section C.10.10 of RG 5.71.

- 12 The licensee's CSP contains an inconsistent section heading, which is stated in DBNPS's CSP as Section 4.9, "Evaluate and Manage Cyber Risk." The section title should be, "Policies and Implementing Procedures." The content of this section of the CSP submitted by the licensee does not deviate from Section 4.11 of NEI 08-09, Revision 6. The title should be corrected in a future version of the CSP.

The licensee neglected to specify the title of the senior management official who is responsible for nuclear plant operations. Appendix A, Section 4.10 of NEI 08-09, Revision 6, offers the licensee several optional titles that can be selected, or the licensee can provide a senior management official in keeping with its organizational structure. The licensee does state that "personnel responsible for the management and implementation of the program report to senior nuclear management." This omission does not impede the licensee's assurance that policies and procedures will be managed in a manner consistent with the requirements specified in Appendix A, Section 4.10 of NEI 08-09, Revision 6.

Based on the licensee's statement in its CSP that the personnel responsible for the management and implementation of the Cyber Security Program will report to senior nuclear management, the NRC staff finds that the CSP adequately described cyber security policies and implementing procedures.

3.19 Roles and Responsibilities The licensee's CSP describes the roles and responsibilities for the qualified and experienced personnel, including the Cyber Security Program Sponsor, the Cyber Security Program Manager, Cyber Security Specialists, the Cyber Security Incident Response Team (CSIRT), and other positions as needed. The CSIRT initiates in accordance with the Incident Response Plan and initiates emergency action when required to safeguard CDAs from cyber security compromise and to assist with the eventual recovery of compromised systems. Implementing procedures establish roles and responsibilities for each of the cyber security roles in accordance with Appendix A, Section 4.11 of NEI 08-09, Revision 6, which is comparable to Regulatory Position C.3.1.2, Appendix A, Section A3.1.2, and Appendix C, Section C.1 0.1 0 of RG 5.71.

The licensee's CSP contains deviations to the roles and responsibilities defined in the NEI 08-09, Revision 6, for the Cyber Security Program Manager and Cyber Security Specialist and creates a new role, Site Cyber Security Program Administrator. The roles and responsibilities deviations are as follows:

In addition to the responsibilities listed in the NEI 08-09, Revision 6, description, this position also interfaces with the newly created position, Site Cyber Security Program Administrator.

The licensee CSP states that the position can also be a Cyber Security SpeCialist, but the assigned duties indicate the person in this position will be a lead Cyber Security Specialist. The responsibilities are:

- 13 o "Function as a single point of contact for issues related to cyber security"; this is formerly the responsibility of the Cyber Security Program Manager, but the distinction is made between the site/plant responsibilities of the Site manager and the corporate focus of the Cyber Security Program Manager.

o "Initiates and coordinates the Cyber Security Incident Response Team (CSIRT) functions as required;" this is formerly the duty of the Cyber Security Program Manager as specified in NEI 08-09, Revision 6.

o "Conduct cyber security audits, network scans, and penetration tests against CDAs as necessary;" this is formerly the duty of the Cyber Security Specialist as specified in NEI 08-09, Revision 6.

o "Participates in the development and operation of the cyber security education, awareness, and training program;" this is a new responsibility not cited in the NEI 08-09, Revision 6, description for any position. The Site Cyber Security Program Administrator will be responsible for developing and operating programs that are approved by the Corporate Cyber Security Program Manager.

o "Participates in the development and implementation of cyber security policies and procedures;" this is a new responsibility not cited in the NEI 08-09, Revision 6, description for any position. The Site Cyber Security Program Administrator will be responsible for developing and implementing cyber security policies and procedures that are approved by the Corporate Cyber Program Manager.

  • In addition to the responsibilities that were transferred to the Site Cyber Security Program Administrator, as specified in NEI 08-09, Revision 6, an additional deviation was noted, whereby the licensee assigned the Cyber Security Specialist role the responsibility to:

o "Ensure cyber security assessments of CDAs are performed and documented prior to being presented to CSAT for review and approval, this may include documenting the assessments or reviewing assessments provided by another organization such as Engineering, Emergency Preparedness, or Security, or a combination. "

  • The role of "Others" in NEI 08-09, Revision 6, refers to operators, engineers, technicians, and users who perform their assigned duties in accordance with the non-CSAT staff with the preparation of cyber security controls documentation, deviated from the NEI 08-09, Revision 6, text by inserting the phrase, "including performing and documenting cyber security assessments of the CDAs, as requested by a Cyber Security Specialist." This deviation supports the licensee's approach, as discussed in Section 3.4, "Cyber Security Assessment Team," and Section 3.8, "Mitigation of Vulnerabilities and Application of Cyber Security Controls" of this SE.

While the licensee deviated from NEI 08-09, Revision 6, in Section 4.1.1 of its CSP, all of the specific roles and responsibilities have been designated to one of several cyber security

- 14 personnel. Based on the licensees' cyber security plan adequately addressing all of the roles and responsibilities, the NRC staff finds that the CSP adequately described cyber security roles and responsibilities.

3.20 Cyber Security Program Review The licensee's CSP describes how the Cyber Security Program establishes the necessary procedures to implement reviews of applicable program elements in accordance with Appendix A, Section 4.12 of NEI 08-09, Revision 6, which is comparable to Regulatory Position CA.3 and Appendix A, Section AA.3 of RG 5.71.

Based on the above, the NRC staff finds that the CSP adequately describes Cyber Security Program review.

3.21 Document Control and Records Retention and Handling The licensee's CSP describes how the licensee has established the necessary measures and governing procedures to ensure that sufficient records of items and activities affecting cyber security are developed, reviewed, approved, issued, used, and revised to reflect completed work. The CSP described that superseded portions of certain records will be retained for at least three years after the record is superseded, while audit records will be retained for no less than 12 months in accordance with Appendix A, Section 4.13 of NEI 08-09, Revision 6.

However, this guidance provided by industry to licensees did not fully comply with the requirements of 10 CFR 73.54.

In a letter dated February 28, 2011 (ADAMS Accession No. ML110600204), NEI sent to the NRC proposed language for licensees to use to respond to the generic records retention issue, to which the NRC had no technical objection and responded to NEI in a letter dated March 1, 2011 (ADAMS Accession No. ML110490337). The proposed language clarified the requirement by providing examples (without providing an all-inclusive list) of the records and supporting technical documentation that are needed to satisfy the requirements of 10 CFR 73.54. All records will be retained until the Commission terminates the license, and the licensee shall maintain superseded portions of these records for at least three years after the record is superseded, unless otherwise specified by the Commission.

By retaining accurate and complete records and technical documentation until the license is terminated, inspectors, auditors, or assessors will have the ability to evaluate incidents, events, and other activities that are related to any of the cyber security elements described, referenced, and contained within the licensee's NRC-approved CSP. It will also allow the licensee to maintain the ability to detect and respond to cyber attacks in a timely manner in case of an event. In a letter dated April 8, 2011, the licensee responded to the records retention issue using the language proposed by NEI in its letter dated February 28, 2011.

This section of the CSP submitted by the licensee is comparable to Regulatory Position C.5 and Appendix A, Section A.5 of RG 5.71, without deviation.

- 15 Based on the above, the NRC staff finds that the language the licensee proposes to adopt provides for adequate records retention and will support the licensee's ability to detect and respond to cyber attacks. The NRC staff further finds that this section is comparable to Regulatory Position C.5 and Appendix A, Section A.5 of RG 5.71, without deviation.

Accordingly, the NRC staff finds that the CSP adequately describes cyber security document control and records retention and handling.

3.22 Implementation Schedule The licensee's CSP provides a proposed implementation schedule for the Cyber Security Program. In a letter dated February 28, 2011 (ADAMS Package Accession No. ML110600206),

NEI sent to the NRC a template for licensees to use to submit their CSP implementation schedules, to which the NRC had no technical objection responded to NEI in a letter dated March 1, 2011 (ADAMS Accession No. ML110070348). These key milestones include:

  • Establish the CSA T;
  • Install a deterministic one-way device between lower level devices and higher level devices;
  • Implement the security control "Access Control For Portable And Mobile Devices" as described in Appendix D 1.19 of NEI 08-09, Revision 6;
  • Implement observation and identification of obvious cyber-related tampering to existing insider mitigation rounds by incorporating the appropriate elements;
  • Identify, document, and implement cyber security controls as per "Mitigation of Vulnerabilities and Application of Cyber Security Controls" for CDAs that could adversely impact the design function of physical security target set equipment; a
  • Commence ongoing monitoring and assessment activities for those target set CDAs whose security controls have been implemented: and In the letter dated April 8, 2011, the licensee provided a revised implementation schedule using the NEI template, with the exception of Milestone 6. The licensee revised Milestone 6 to address only the NEI 08-09, Revision 6, Appendix D, technical controls, excluding the operational and management controls, on the basis that implementing the technical controls for target set CDAs provides a high degree of protection against cyber-related attacks that could lead to radiological sabotage. Furthermore, the licensee explained that existing licensee programs that are currently in place (e.g., physical protection, maintenance and work management, and configuration management, operational experience, etc.) provide a high degree of operational and management protection during the interim period until such time that the full Cyber Security Program is implemented.

- 16 3.23 Addition of License Condition In its submitted dated April 8, 2011, the licensee proposed to add a paragraph to the existing FOL license condition related to physical security, training and qualification, and safeguards contingency plans. The following paragraph is added to DBNPS's FOL No. NPF-3:

FENOC shall fully implement and maintain in effect all provisions of the Commission-approved cyber security plan (CSP), including changes made pursuant to the authority of 10 CFR 50.90 and 10 CFR 50.54(p). The FENOC CSP was approved by License Amendment No. 283.

Based on the information in Section 3.0 of this SE and the modified license condition described above, the NRC concludes this is acceptable.

4.0 DIFFERENCES FROM NEI 08-09, REVISION 6 The NRC staff notes the following additional differences between the licensee's submission and NEI 08-09, Revision 6:

  • In Section 3.1, "Scope and Purpose," the licensee clarified the definition of important-to-safety functions, consistent with SRM-COMWCO-10-0001.
  • In Section 3.8, "Mitigation of Vulnerabilities and Application of Cyber Security Controls," the licensee deviated by stating in the case of implementing alternative controls/countermeasures that eliminate threat/attack vector(s) associated with one or more of the cyber security controls, that either an alternative countermeasure that provides at least the same degree of cyber security protection as the corresponding cyber security control will be implemented or an alternative frequency or periodicity for the security control will be implemented.
  • In Section 3.18, "Policies and Implementing Procedures," the licensee did not provide the title of the senior management official who is responsible for nuclear plant operations.
  • In Section 3.19, "Roles and Responsibilities," the licensee deviated by assigning some of the specific roles and responsibilities to cyber security personnel in a manner that is different than the NEI 08-09, Revision 6; all roles and responsibilities are assigned.
  • In Section 3.21, "Document Control and Records Retention and Handling," the licensee clarified the definition of records and supporting documentation that will be retained to conform to the requirements of 10 CFR 73.54.

- 17

  • In Section 3.22, "Implementation Schedule," the licensee submitted a revised implementation schedule, specifying the interim milestones and the final implementation date, including supporting rationale. The licensee deviated from the template for Milestone 6 to address only the NEI 08-09, Revision 6, Appendix D technical controls.

The NRC staff finds all of these deviations to be acceptable as discussed in the respective sections.

5.0 STATE CONSULTATION

In accordance with the Commission's regulations, the Ohio State official was notified of the proposed issuance of the amendment. The State official had no comments.

6.0 ENVIRONMENTAL CONSIDERATION

This amendment changes a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20. The NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluent that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involve no significant hazards consideration and there has been no public comment on such finding published in the Federal Register on February 1, 2011 (76 FR 5621). Also, this amendment relates to safeguards matters and do not involve any significant construction impacts and relates to changes in recordkeeping, reporting, or administrative procedures or requirements. Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9), (10), and (12). Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.

7.0 CONCLUSION

The NRC staff's review and evaluation of the licensee's CSP was conducted using NRC staff positions established in the relevant sections of RG 5.71. Based on the NRC staffs review, the NRC finds that the licensee addressed the relevant information necessary to satisfy the requirements of 10 CFR 73.54, 10 CFR 73.55(a)(1), 10 CFR 73.55(b)(8), and 10 CFR 73.55(m),

as applicable and that the licensee's Cyber Security Program provides high assurance that digital computer and communication systems and networks associated with the following are adequately protected against cyber attacks, up to and including the DBT as described in 10 CFR 73.1. This includes protecting digital computer and communication systems and networks associated with: 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 SSEP functions.

Therefore, the NRC staff finds the information contained in this CSP to be acceptable and upon successful implementation of this program, operation of DBNPS will not be inimical to the common defense and security.

- 18 The NRC staff has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission regulations, and (3) the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
