this document to reflect the norm among nuclear asset owners and operators Nuclear Sector Cybersecurity Framework Implementation Guidance for U S Nuclear Power Reactors v 1 Executive Summary and Introduction Background The National Institute of Standards and Technology NIST released the voluntary Framework for Improving Critical Infrastructure Cybersecurity NIST 2014 hereafter called the Framework in February 2014 to provide a common language organizations can use to assess and manage cyber security risk Developed in response to Executive Order EO 13636 Improving Critical Infrastructure Cybersecurity of February 2013 the Framework recommends risk management processes that enable organizations to inform and prioritize decisions regarding cyber security based on business needs without additional regulatory requirements It enables organizationsregardless of sector size degree of cyber security risk or cyber security sophisticationto apply the principles and effective practices of risk management to improve the security and resilience of critical infrastructure To encourage and assist with Framework use the EO also established the Critical Infrastructure Cyber Community C Voluntary Program which serves as a central repository for government and private sector tools and resources to support the use of the Framework by sector owners and operators and enhance their cyber risk management practices The Framework based on a collection of cyber security standards and industry best practices Provides guidance on risk management principles and best practices Provides common language to address and manage cyber security risk Outlines a structure for organizations to understand and apply cyber security risk management and Identifies effective standards guidelines and practices to manage cyber security risk in a cost-effective way based on business needs The Framework is designed to complement and not replace or limit an organizations risk management process and cyber security program Each sector and individual organization can use the Framework in a tailored manner to address its cyber security objectives Purpose of the Implementation Guidance Nuclear reactors in the United States have a strong track record of working together to develop and implement cyber security standards tools and processes that ensure safety security and reliability The U S Department of Homeland Security DHS as the Nuclear Reactors Materials and Waste Sector-Specific Agency worked with the Nuclear Sector Coordinating Council to develop this Implementation Guidance specifically for nuclear power reactor owners and operators It is informed by the nuclear reactor risk environment and existing physical and cyber security programs as well as other risk management tools used within the sector This Implementation Guidance is designed to assist nuclear power reactor organizations to Characterize their current and target cyber security posture Identify gaps in their existing cyber security risk management programs using the Framework as a guide and identify areas where current practices may exceed the Framework Recognize that existing sector tools standards and guidelines may support Framework implementation Effectively demonstrate and communicate their risk management approach and use of the Framework to both internal and external stakeholders Nuclear Sector Cybersecurity Framework Implementation Guidance for U S Nuclear Power Reactors 1 This document describes how the practices and programs at U S nuclear power reactors implement the

management approaches to the Frameworks Core and Implementation Tiers and Appendix B provides a summary table of the inputs activities and outputs for each step in the Framework implementation process Appendix C includes a table of terms found within this document Aside from the term organization the glossary is excerpted verbatim from the Framework Nuclear Sector Cybersecurity Framework Implementation Guidance for U S Nuclear Power Reactors 2 2 History of Nuclear Power Reactor Cyber Security The nuclear energy industry is one of the Nations safest industries It is protected by multiple back-up safety systems robust physical defenses and plant security forces with rigorous training Since the September 11 terrorist attacks the industry has continued to improve its safety systems to prepare for emerging threats such as the impact from a widebodied commercial airliner and cyberattacks on critical operational systems Each U S nuclear power plant is equipped with extensive security measures to protect the facility from intruders and to protect the public from the possibility of exposure to radioactive releases caused by acts of sabotage The U S Nuclear Regulatory Commission NRC calls nuclear power plants among the best-protected private sector facilities in the nation The Nuclear Sector has a long history of addressing cyber security issues In 1997 through the Nuclear Energy Institute NEI the industry began looking at potential issues associated with the increasing use of digital technologies at power reactors At this time there was a concern regarding the potential impacts associated with the change in millennia referred to at that time as the Y2K issue Following the terrorist attacks of September 11 2001 the industry turned its focus to potential cyber security-related issues In January 2002 NEI established a Cyber Security Task Force CSTF initially composed of 23 members to provide an industry-wide forum for identifying discussing and resolving cyber security issues In March 2002 the NRC issued Interim Compensatory Measures ICM Orders that directed licensees to consider and address cyber safety and security vulnerabilities During 2003 and 2004 the industry was engaged in the development of guidance documents intended to support the uniform implementation of cyber security programs at power reactors In July 2003 cyber security assessment pilots were completed at four U S nuclear power reactors These pilots were designed to inform development of NUREG CR-6847 Cyber Security Self-Assessment Method for U S Nuclear Power Plants The project team consisted of representatives from the Pacific Northwest National Laboratory PNNL the NRC and the CSTF NUREG CR-6847 was released in November 2004 In November 2005 NEI released NEI 04-04 Cyber Security Program for Power Reactors Revision 1 NEI 04-04 provides guidance on establishing and maintaining a cyber security program and incorporates assessment methodology described in NUREG CR-6847 The NEI 04-04 program provides for the cyber security protection of all systems in the plant including those necessary for reliable electrical generation The guidance provides a risk-informed approach where consequences to plant functions are considered and provides guidance on establishing a site cyber security defensive strategy incorporating multiple defensive layers with increasing levels of security protection NEI 0404 also provides guidance on incorporating cyber security considerations into the procurement process The NEI 04-04 program includes the following steps 1 2 3 4 5 6 7 8 Define current cyber security program Identify Critical Digital Assets CDAs Validate configuration Assess susceptibility Assess consequences Determine risk Refine defensive strategy Continue program management In December 2005 the NRC informed NEI by letter that Nuclear Energy Institute NEI 04-04 Cyber Security Program for Power Reactors Revision 1 dated November 18 2005 is an acceptable method for establishing and maintaining a cyber security program at nuclear power plants In 2006 the North American Electric Reliability Corporation NERC Nuclear Sector Cybersecurity Framework Implementation Guidance for U S Nuclear Power Reactors 3 acknowledged that the NEI 04-04 program provides cyber security protection equivalent to the NERC Critical Infrastructure Protection CIP Reliability Standards The nuclear industry established a Nuclear Strategic Issues Advisory Committee NSIAC that has the ability to establish initiatives binding to all nuclear power plants The NSIAC is comprised of the Chief Nuclear Officers of each power plant site or fleet Approved NSIAC initiatives are implemented at all U S nuclear power plants In April 2006 the NSIAC established an initiative requiring nuclear power plants to implement NEI 04-04 within two years All U S plants implemented the initiative by May 2008 Power plants are required by the NRC to design implement and evaluate their physical and cyber security programs to defend against a Design Basis Threat DBT In response to the increasing threat of cyber-related attacks the NRC amended its design basis threat requirements in 2007 to include a cyberattack as an attribute of the adversary The NRC describes a cyberattack as The capability to exploit site computer and communications system vulnerabilities to modify or destroy data and programming code deny access to systems and prevent the operation of the computer system and the equipment it controls In March 2009 the NRC issued revised security requirements that included comprehensive programmatic cyber security requirements principally codified in Title 10 of the Code of Federal Regulations CFR Section 10 CFR 73 54 Protection of Digital Computer and Communication Systems and Networks Rule The Rule requires power plants to submit a cyber security plan and implementation schedule for NRC review and approval To support uniform implementation the industry developed a template for the cyber security plan and the implementation schedule In May 2010 the NRC endorsed NEI 08-09 Cyber Security Plan for Nuclear Power Reactors Revision 6 NEI 08-09 provides a template for cyber security plans and a catalog of technical operational and management cyber security controls tailored from the NIST Special Publication SP 800-53 Recommended Security Controls for Federal Information Systems Revision 2 The template for the implementation schedule provides eight milestonesseven interim milestones and an eighth milestone for full implementation The first seven milestones are designed to address the most prominent threats to the plants most important systems These milestones include the establishment of a cyber security assessment team hardware-based isolation of key networks and assets tightening controls over portable media and equipment enhancing existing insider threat mitigation instituting protective measures for digital equipment that could impact key safety systems and establishing ongoing monitoring and assessment activities for implemented cyber security measures By December 31 2012 each plant completed the initial seven milestones Post-2012 activities the eighth milestone include the completion of policy and procedural revisions that enhance existing capabilities the completion of any remaining design-related modifications necessary to implement the cyber security plan and institution of protective measures for lower consequence assets In January 2013 the NRC began inspecting power plant cyber security program implementation of the initial seven milestones and completed inspections at each power plant at the end of 2015 Nuclear Sector Cybersecurity Framework Implementation Guidance for U S Nuclear Power Reactors 4 3 Framework Implementation Overview This section opens with an overview of key Framework terminology and concepts followed by a subsection describing the purpose of this Implementation Guidance The final subsection highlights some of the benefits of using the Framework Please refer to the glossaries in the Framework NIST 2014 for full definitions of additional terms used throughout this document Framework Guidance Terminology The three main components of the Framework are the Core the Framework Implementation Tiers Tiers and the Profile These terms are frequently used in this Implementation Guidance and defined below The Core is a set of cyber security activities desired outcomes and applicable Informative References that are common across critical infrastructure sectors The Core comprises four elements Functions Categories Subcategories and Informative References Functions provide a high-level strategic view of the lifecycle of an organizations management of cyber security There are five Functions Identify Protect Detect Respond and Recover Each Function is divided into Categories Subcategories and Informative References The Categories are cyber security outcomes that are closely tied to programmatic needs and particular activities The Subcategories are specific outcomes of technical and or management activities that support achievement of each Category Informative References are specific cross-sector standards guidelines and effective practices that illustrate a method to achieve the outcomes associated with each Subcategory Tiers describe an organizations approach to cyber security risk and the processes in place to manage that risk ranging from Tier 1 Partial to Tier 4 Adaptive Each Tier demonstrates an increasing degree of rigor and sophistication of cyber security risk management and integration with overall organizational needs Progression to higher Tiers is encouraged when such a change would cost-effectively reduce cyber security risk Tiers are associated with the overall robustness of an organizations risk management process and are not tied to Functions Categories or Subcategories An organization may align its application of the Tiers with its desired scope for using the Framework For example if an organization chooses to use the Framework only for a specific business unit or process the Tiers could be used to describe the overall robustness of risk management processes at that business unit or process level See the definition below for how organization is used in this document Profiles align the Framework core elements with business requirements risk tolerance and organizational resources The Profile can be used to identify opportunities for improving cyber security posture by comparing a Current Profile to a Target Profile Profiles provide a roadmap to reduce cyber security risk consistent with business practices This document also frequently refers to the term organization which describes an operational entity of any size that uses the same cyber security risk management program within its different components and may individually use the Framework This may describe one corporation or one business unit or process within a multi-unit corporation For the purposes of this Implementation Guidance organization is synonymous with nuclear power plant Framework Guidance Purpose Given the broad nature of the Framework components described above organizations cannot simply be compliant with the Framework or adopt it Indeed organizations have unique cyber security risks including different threats vulnerabilities and tolerances all of which benefit from investing in cyber security risk management Individual organizations must apply Framework principles best practices standards and guidelines to their specific context and needs Nuclear Sector Cybersecurity Framework Implementation Guidance for U S Nuclear Power Reactors 5 The nuclear sector embraces the flexibility offered by the Framework but recognizes organizations potential need for more guidance on how to apply the Framework to their suit their particular needs With this in mind the Sector Coordinating Council SCC and DHS Sector Outreach and Programs Division SOPD worked with sector stakeholders and the DHS Critical Infrastructure Cyber Community C3 Voluntary Program to develop this Implementation Guidance which was designed to enhance understanding of Framework terminology concepts and benefits Existing sector cyber security tools and resources that support Framework use A standard approach for using the Framework and Suggestions for how to link organizational cyber risk management activities to the Nuclear Sector It is important to note that the Framework includes considerations to address privacy and civil liberties issues during implementation In the Nuclear Sector these issues are not directly applicable to safety or reliability Although this Implementation Guidance does not directly address privacy and civil liberties issues organizations are encouraged to review and consider using the Frameworks privacy and civil liberties guidance NIST 2014 p 15 in alignment with other privacy guidelines and State and Federal laws Framework Implementation Benefits The Framework is designed to be flexible enough to be used both by organizations with mature cyber security and risk management programs and by those with less-developed programs Implementation of the Framework does not imply that existing cyber security and risk management approaches are ineffective or need to be replaced Rather implementation means that the organization wishes to take advantage of the benefits that the Framework offers In general implementing the Framework provides a mechanism for organizations to Assess and specifically describe its current and targeted cyber security posture Identify gaps in its current programs processes and workforce Identify and prioritize opportunities for improvement using a continuous and repeatable process Assess progress toward reaching its target cyber security posture Demonstrate the organizations alignment with the Frameworks nationally recognized best practices Highlight any current practices that might surpass the Frameworks recommended practices Communicate its cyber security posture in a common recognized language to internal and external stakeholdersincluding customers regulators investors and policy makers Implementing the Framework can help organizations to strengthen their existing cyber security risk management approach and more easily communicate their use of particular cyber security practices to internal and external stakeholders Organizations with less-developed cyber security risk management programs can use the Framework to define and establish a program that successfully addresses cyber security risk and communications commensurate with the organizations business and critical infrastructure security objectives U S nuclear power plants have mature risk management programs This document describes how the programs at nuclear power plants implement the Framework The implementation detailed in Section 5 describes Framework implementation and Appendix A maps existing cyber security and risk management approaches e g standards tools methods and guidelines to the Frameworks Core and Implementation Tiers Early adoption of the Frameworks principles may better position nuclear power plants to receive additional potential benefits in the future More attractive cyber security insurance coverage As cyber risks grow insurance agencies are developing new and refined approaches to evaluate clients premiums based on their use of sound cyber security practices Nuclear Sector Cybersecurity Framework Implementation Guidance for U S Nuclear Power Reactors 6 Insurance coverage may increasingly encourage or require the use of nationally recognized cyber risk management processes Framework implementation provides an additional widely accepted means for an organization to measure its cybersecurity posture and demonstrate continuous improvement Prioritized funding or technical assistance The Federal Government provides several hands-on tools that will help an organization assess their current-state of cyber security practices and identify areas to grow their cyber security resilience Commercial Facilities Sector organizations are encouraged to visit the US-CERT Critical Infrastructure Community C3 Voluntary Program Webpage for additional information related to both facilitated and self-service risk assessment resources The Federal government uses this assessment to help organizations prioritize next steps depending on their level of cyber security maturity For example the government offers preparedness support assessments training of employees and advice on best practices Under this incentive the primary criteria for assistance would be criticality security and resilience gaps Owners and operators in need of incident response support will never be denied assistance based on cyber security maturity and or level of prior engagement with the use of the Framework Demonstration of commitment to cyber security The Framework does not protect any organization from liability in the event of a cyber incident However implementation of the Framework provides an organization with a mechanism to demonstrate its proven track record of implementing and continuously evaluating cyber risk management practices appropriate for its individual risks Government recognition For interested organizations DHS seeks to recognize those organizations and sectors that use the Framework and participate in the C3 Voluntary Program regardless of size and maturity level Workforce development Organizations that use the Framework will have a better understanding of the technical capabilities their organization requires and therefore the skills required of their cyber workforce A more accurate understanding of these needs can guide activities such as recruiting workforce design and training of existing personnel Nuclear Sector Cybersecurity Framework Implementation Guidance for U S Nuclear Power Reactors 7 4 Sector Framework Guidance Resources This section presents an overview of the NRCs risk management program and cyber security requirements and guidance Nuclear Sector Risk Management The NRC was created as an independent agency by Congress in 1974 to ensure the safe use of radioactive materials for beneficial civilian purposes while protecting people and the environment The NRC uses licensing inspection and enforcement of its requirements to regulate commercial nuclear power reactors and other uses of nuclear material such as in medicine NRC's regulatory mission covers three main areas ReactorsCommercial reactors for generating electric power and research and test reactors used for research testing and training MaterialsUses of nuclear materials in medical industrial and academic settings and facilities that produce nuclear fuel and WasteTransportation storage and disposal of nuclear materials and waste and decommissioning of nuclear facilities from service The NRC imposes security requirements in a risk-informed manner for their licensees with the objective of ensuring public health and safety and common defense and security Overview of NRC Power Reactor Requirements and Guidance The NRC has established requirements for cyber security programs for nuclear power reactors The cyber security requirements are codified primarily in 10 CFR 73 54 These cyber security requirements are an integrated component of the NRCs overall physical protection program requirements that include physical security cyber security and personnel security The requirements establish a comprehensive cyber security program for the protection of digital computer and communications systems and equipment against cyberattacks that would adversely impact operational safety security or emergency preparedness Also protected are digital assets associated with electric power generation equipment The program includes key cyber security program elements including the identification of in-scope assets implementation of security controls defense-in-depth measures for detection response and recovery managing cyber risks training integration of cyber security and physical security programs development and maintenance of written policies and implementing procedures reviewing the cyber security program and records retention To support implementation of the cyber security requirements in 10 CFR 73 54 the NRC has issued and endorsed a number of approaches Although a more complete list can be found in Section 8 notable guidance documents are summarized in Table 1 Nuclear Sector Cybersecurity Framework Implementation Guidance for U S Nuclear Power Reactors 8 TABLE 1 Key U S Nuclear Power Reactor Cyber Security Guidance Documents Name Summary Additional Information NEI 08-09 Cyber Security Plan for Nuclear Power Reactors NEI 08-09 provides a template for the cyber security plan The plan includes a defensive strategy that consists of a defensive architecture and set of security controls that are based on the NIST SP 800-82 Final Public Draft Dated September 29 2008 Guide to Industrial Control System Security and NIST SP 800-53 Revision 2 Recommended Security Controls for Federal Information Systems standards Cyber Security Plan for Nuclear Power Reactors Template for the Cyber Security Plan Implementation Schedule Provides a template used by each operating power plant to establish the schedule for the implementation of their cyber security plans Each operating plant has completed the first seven milestones provided in the template Cyber Security Plan Implementation Schedule RG 5 71 Cyber Security Programs for Nuclear Facilities RG 5 71 is similar to NEI 08-09 in

basis for their Cyber Security Plans Because of the similarities between RG 5 71 and NEI 08-09 this Framework mapping is applicable to new plants as well Cyber Security Programs for Nuclear Facilities Mapping to the Framework Section 5 details the Framework implementation using the existing practices as well as requirements and guidance applicable to nuclear power plants A mapping of these elements to the Framework is provided in Appendix A The mapping provides a translation between the organizations current practices and the Framework supporting communication to external stakeholders Nuclear Sector Cybersecurity Framework Implementation Guidance for U S Nuclear Power Reactors 9 5 Approach to Framework Implementation This section describes how the seven-step process outlined in Section 3 2 in the Cybersecurity Framework was used to demonstrate how cyber security practices at U S nuclear power plants align to the Framework Established practices common at plants as well as those required by regulatory requirements were used Where possible references to specific documents or requirements are provided FIGURE 1 Framework Implementation Process Step 1 Prioritize and Scope Identify business missionobjectives and strategic priorities Describe cyber security risks Determine organizational components to use Framework Step 7 Implement Action Plan Step 2 Orient Implement necessary actions cyber security practices against Target Profile Identify the systems assets requirements and risk management approaches Determine how to evaluate current risk management and cyber security posture Monitor Step 6 Determine Analyze and Prioritize Gaps Step 3 Create Current Profile Compare Current Profile and Target Profile Determine resources to address gaps and create a prioritized Action Plan Step 5 Create a Target Profile Describe desired cyber security outcomes Account for unique risks Develop Target Profile Develop Target Implementation Tier Map current cyber security and risk management practices to a Framework Implementation Tier Step 4 Conduct a Risk Assessment Identify cyber security risks and analyze risks Identify risks above tolerances Evaluate Each step is introduced by a table describing the steps inputs activities and outputs Additional explanation is provided below each table as needed A summary table of the inputs activities and outputs for each step is included in Appendix B Nuclear Sector Cybersecurity Framework Implementation Guidance for U S Nuclear Power Reactors 10 An organization may repeat the steps as needed to continuously assess and improve its cyber security For instance organizations may find that more frequent repetition of Step 2 Orient improves the quality of risk assessments Furthermore organizations may monitor progress through iterative updates to the Current Profile subsequently comparing the Current Profile to the Target Profile Organizations may also use this process to align their cyber security program with their desired Framework Implementation Tier U S nuclear power plants already have comprehensive risk management programs that establish the context for risk-based decisions by allowing them to assess risk address identified risk and monitor risk on an ongoing basis The plants also use corrective action programs assessments and audits for continuous improvement This section demonstrates how the activities described in these seven steps are already performed Accordingly this document describes how the plants implement the Framework by describing and aligning or translating elements of their current approach to the Framework Core and Implementation Tiers Step 1 Prioritize and Scope Inputs 1 Risk management strategy 2 Organizational objectives and priorities 3 Threat information

cyber security program covering the digital assets described in Step 1 Prioritize and Scope above The NRCs cyber security requirements are codified primarily in 10 CFR 73 54 Each plant has submitted and the NRC has approved a cyber security plan Plan and implementation schedule Schedule The Plan describes how the cyber security requirements will be met and the Schedule describes when the Plan will be implemented The plants have used an industry-wide template for both the Plan and Schedule In accordance with the Schedule each power plant identified the digital systems and equipment in scope for their cyber security programs by December 31 2012 By the end of 2015 the NRC will complete inspecting each plants identification of digital assets The in-scope cyber security and risk management standards tools methods and guidelines include the physical cyber and personnel security requirements codified in 10 CFR 73 54 10 CFR 73 55 and 10 CFR 73 56 respectively Guidance most applicable to this Framework mapping include the industrys NEI 08-09 NEI 10-04 and NEI 13-10 The standards tools methods and guidelines regarding information security are included within the requirements codified in 10 CFR 73 21 and 10 CFR 73 22 and their associated implementing guidance documents A more detailed list of guidance and requirements can be found in Section 8 Step 3 Create a Current Profile Inputs

integrated into both the design of the facility and its operations and oversight With a fundamental focus on safety risk-significant systems structures and components SSCs are identified and the plant is physically designed to ensure that those SSCs are not adversely impacted by a range of hazards This focus on safety is fed forward from the design into the operations and oversight of power plants Nuclear Sector Cybersecurity Framework Implementation Guidance for U S Nuclear Power Reactors 12 Additionally U S nuclear power plants have an approved Plan and Schedule making their Current and Target Profiles and Implementation Tiers easily determined The Current and Target Profiles and an assessment of the Implementation Tier are provided in Appendix A The Profiles are informed by the uniform Plan and Schedule Although the Current Profile recognizes that the Plans are partially implemented the Target Profile was implemented for a subset of plant equipment by December 31 2012 Based on the Current Profile and Implementation Tier assessment described in Appendix A the current Implementation Tier is between Tier 3 Repeatable and Tier 4 Adaptive Upon full implementation of the Plan the Implementation Tier will be Tier 4 Adaptive Step 4 Conduct a Risk Assessment Inputs 1 Framework usage scope 2 Risk management strategy 3 Organization-defined risk assessment approach 4 In-scope

assessment reports The concepts of risks from both natural and manmade hazards are well understood and established for nuclear power plants Each plant has identified sets of plant systems and equipment that are more or less risk significant During the development of the Implementation Schedule this inherent understanding of risk was used to prioritize implementation The Schedule prioritized cyber security program implementation for the subset of plant equipment determined to be most important for protecting the health and safety of the public The Schedule also prioritized the implementation of plantwide mitigations for certain cyber threats including network-based attacks and attacks that promulgate through the use of portable media and portable equipment Because each plant has identified risk-significant systems and equipment and has a risk-informed implementation schedule a separate risk assessment was not performed during the development of this document Step 5

used to increase knowledge and enhance cyber security practices the Framework can make them more effective Critical Infrastructure Cyber Community C3 Voluntary Program The C Voluntary Program is a publicprivate partnership that aligns business enterprises as well as Federal and State local tribal and territorial SLTT governments to existing resources It will assist them in using the Framework to manage their cyber risks as part of an all-hazards approach to enterprise risk management Currently a number of DHS and government agencies provide programs and resources to critical infrastructure sectors and organizations that are looking to improve their cyber risk resilience The C Voluntary Program is the coordination point within the Federal government to leverage and enhance existing capabilities and resources to promote Framework implementation Although the Framework is based on existing guidelines and standards organizations may still need assistance in understanding its purpose and how it may apply to them The C Voluntary Program will provide assistance to organizations of all types interested in using the Framework Nuclear Sector-Specific Plan The Nuclear Sector-Specific Plan SSP is designed to guide the sectors efforts to improve security and resilience and describes how the Nuclear Sector manages risks and contributes to national critical infrastructure security and resilience as set forth in Presidential Policy Directive 21 PPD-21 The SSP reflects the overall strategic direction for the Nuclear Sector and represents the progress made in addressing the sectors evolving risk operating and policy environments As an annex to the National Infrastructure Protection Plan 2013 Partnering for Critical Infrastructure Security and Resilience NIPP 2013 the SSP tailors the NIPPs strategic guidance to the unique operating conditions and risk landscape of the Nuclear Sector Nuclear Sector Cybersecurity Framework Implementation Guidance for U S Nuclear Power Reactors

to the Framework As discussed in Section 5 of this Implementation Guidance cyber security programs at nuclear power plants can be mapped to the Framework Core and Implementation Tiers to demonstrate their implementation of the Framework U S nuclear power reactors established comprehensive and integrated operational and security risk management programs long before cyber security concerns warranted separate risk management attention Accordingly and to more fully inform the Framework mapping Table A1 provides an overview of how various programs at power reactors support implementation of the Framework These other programs include for example maintenance work management configuration management and corrective action programs that support safety and reliability Power reactor physical protection programs existed before the NRCs new requirements for cyber security programs and implement comprehensive physical security personnel security access controls and information security practices A stand-alone review of the Cyber Security Plan at U S nuclear power reactors would not provide an adequate representation of the comprehensive and integrated nature of established operational and security risk management programs The cyber security programs do not necessarily establish or implement these other programs however the cyber security program may supplement or enhance them Table A1 identifies these enhancements The overview is followed by a two-part mapping These mappings provide detail for how plant practices meet the intent of the Framework Table A2 maps the Framework Core and the nuclear reactor cyber security program practices At the time of this writing the Profile identified in Table A2 is currently achieved at all U S nuclear reactors for systems and equipment essential to safety and security Progress toward the Profile is underway and will be achieved by 2017 based on each reactors Implementation Schedule The Profile column in Table A2 references applicable sections of the Plan and cyber security controls from NEI 08-09 The cyber security controls were tailored from the controls in NIST SP 800-53 The Plan sections and cyber security
