2 A Brief Commercial Interruption Industrial Control System Cybersecurity Seminar Wednesday, April 27, :00 AM to 4:30 PM MS Benbow and Associates $325 Members / $450 Non-Members 8 PDHs Until recently, the reasons for securing Supervisory Control and Data Acquisition (SCADA) or Industrial Control Systems (ICS) weren t always that compelling to the end user. But cyber-attacks on are on the rise with the increased convergence of plant operations with IT infrastructure. The risks are certainly greater with critical infrastructure facilities such as Power, Oil & Gas, or Water/Wastewater plants. But smaller less critical processes are also exposed to cyber-attacks which can pose significant risks to human health and safety, the environment, and business operations. 2

3 Origin of the Framework EO Recognizing that the national and economic security of the United States depends on the reliable functioning of critical infrastructure, the President issued Executive Order (EO) 13636, Improving Critical Infrastructure Cybersecurity, on February 12, The Order directed the National Institute of Standards and Technology (NIST) to work with stakeholders to develop a voluntary framework based on existing standards, guidelines, and practices - for reducing cyber risks to critical infrastructure. It is the policy of the United States to enhance the security and resilience of the Nation s critical infrastructure and to maintain a cyber environment that encourages efficiency, innovation, and economic prosperity while promoting safety, security, business confidentiality, privacy, and civil liberties. 3

4 Background on the Framework Created through collaboration between industry, academia, and government, the Framework consists of standards, guidelines, and practices to promote the protection of critical infrastructure. The prioritized, flexible, repeatable, and cost-effective approach of the Framework helps owners and operators of critical infrastructure to manage cybersecurity-related risk. Version 1.0 of the Framework for Improving Critical Infrastructure was issued by on February 12, 2014 NIST continues to facilitate the awareness, use, and growth of the Framework across the country and around the world. 4

5 Framework Components Framework Core - a set of cybersecurity activities, desired outcomes, and applicable references that are common across critical infrastructure sectors. Framework Profiles - represents the cybersecurity outcomes based on business needs that an organization has selected from the Framework Core Categories and Subcategories. Framework Implementation Tiers - provide context on how an organization views cybersecurity risk and the processes in place to manage that risk. 5

6 What is the Framework Core? The Framework Core is a set of cybersecurity activities, desired outcomes, and applicable references that are common across critical infrastructure sectors. Example language of a desired outcome - physical devices and systems within the organization are inventoried. Language is intended to allow communication across the organization from executive level to operations and implementation levels. Consists of five concurrent and continuous functions with subcategories for each function and informative references Identify, Protect, Detect, Respond, Recover 6

8 Framework Core Functions, Categories, and Subcategories 8

9 Framework Core - Identify Develop the organizational understanding to manage cybersecurity risk to systems, assets, data, and capabilities. The activities in the Identify Function are foundational for effective use of the Framework. Understanding the business context, the resources that support critical functions, and the related cybersecurity risks enables an organization to focus and prioritize its efforts, consistent with its risk management strategy and business needs. Examples of outcome Categories within this Function include: Asset Management; Business Environment; Governance; Risk Assessment; and Risk Management Strategy 9

10 Example - Identify Risk Assessment (ID.RA): The organization understands the cybersecurity risk to organizational operations (including mission, functions, image, or reputation), organizational assets, and individuals. ID.RA-1: Asset vulnerabilities are identified and documented ID.RA-2: Threat and vulnerability information is received from information sharing forums and sources ID.RA-3: Threats, both internal and external, are identified and documented ID.RA-4: Potential business impacts and likelihoods are identified ID.RA-5: Threats, vulnerabilities, likelihoods, and impacts are used to determine risk ID.RA-6: Risk responses are identified and prioritized CCS CSC 4 COBIT 5 APO12.01, APO12.02, APO12.03, APO12.04 ISA : , , , ISO/IEC 27001:2013 A , A NIST SP Rev. 4 CA-2, CA-7, CA-8, RA-3, RA-5, SA-5, SA-11, SI-2, SI-4, SI-5 ISA : , , ISO/IEC 27001:2013 A NIST SP Rev. 4 PM-15, PM-16, SI-5 COBIT 5 APO12.01, APO12.02, APO12.03, APO12.04 ISA : , , NIST SP Rev. 4 RA-3, SI-5, PM-12, PM-16 COBIT 5 DSS04.02 ISA : , , NIST SP Rev. 4 RA-2, RA-3, PM-9, PM-11, SA-14 COBIT 5 APO12.02 ISO/IEC 27001:2013 A NIST SP Rev. 4 RA-2, RA-3, PM-16 COBIT 5 APO12.05, APO13.02 NIST SP Rev. 4 PM-4, PM-9 10

Examples of outcome Categories within this Function include: Response Planning; Communications; Analysis; Mitigation; and Improvements. 16

17 Example - Respond Communications (RS.CO): Response activities are coordinated with internal and external stakeholders, as appropriate, to include external support from law enforcement agencies. RS.CO-1: Personnel know their roles and order of operations when a response is needed RS.CO-2: Events are reported consistent with established criteria RS.CO-3: Information is shared consistent with response plans RS.CO-4: Coordination with stakeholders occurs consistent with response plans RS.CO-5: Voluntary information sharing occurs with external stakeholders to achieve broader cybersecurity situational awareness ISA : , , ISO/IEC 27001:2013 A.6.1.1, A NIST SP Rev. 4 CP-2, CP-3, IR-3, IR-8 ISA : ISO/IEC 27001:2013 A.6.1.3, A NIST SP Rev. 4 AU-6, IR-6, IR-8 ISA : ISO/IEC 27001:2013 A NIST SP Rev. 4 CA-2, CA-7, CP-2, IR-4, IR-8, PE-6, RA-5, SI-4 ISA : NIST SP Rev. 4 CP-2, IR-4, IR-8 NIST SP Rev. 4 PM-15, SI-5 17

18 Framework Core - Recover Develop and implement the appropriate activities to maintain plans for resilience and to restore any capabilities or services that were impaired due to a cybersecurity event. The Recover Function supports timely recovery to normal operations to reduce the impact from a cybersecurity event. Examples of outcome Categories within this Function include: Recovery Planning; Improvements; and Communications. 18

19 Example - Recover Improvements (RC.IM): Recovery planning and processes are improved by incorporating lessons learned into future activities. RC.IM-1: Recovery plans incorporate lessons learned RC.IM-2: Recovery strategies are updated COBIT 5 BAI05.07 ISA NIST SP Rev. 4 CP-2, IR-4, IR-8 COBIT 5 BAI07.08 NIST SP Rev. 4 CP-2, IR-4, IR-8 19

20 Framework Profiles - Definition A Framework Profile ( Profile ) represents the cybersecurity outcomes based on business needs that an organization has selected from the Framework Categories and Subcategories. The Profile can be characterized as the alignment of standards, guidelines, and practices to the Framework Core in a particular implementation scenario. Profiles can be used to identify opportunities for improving cybersecurity posture by comparing a Current Profile (the as is state) with a Target Profile (the to be state). 20

21 Framework Profiles - Development To develop a Profile, an organization can review all of the Categories and Subcategories and, based on business drivers and a risk assessment, determine which are most important. They can also add Categories and Subcategories as needed to address the organization s risks. 21

22 Framework Profiles - Use The Current Profile can then be used to support prioritization and measurement of progress toward the Target Profile, while factoring in other business needs including cost-effectiveness and innovation. Profiles can be used to conduct self-assessments and communicate within an organization or between organizations. 22

23 Implementation Tiers - Definition Framework Implementation Tiers ( Tiers ) provide context on how an organization views cybersecurity risk and the processes in place to manage that risk. Tiers describe the degree to which an organization s cybersecurity risk management practices exhibit the characteristics defined in the Framework (e.g., risk and threat aware, repeatable, and adaptive). The Tiers characterize an organization s practices over a range, from Partial (Tier 1) to Adaptive (Tier 4). These Tiers reflect a progression from informal, reactive responses to approaches that are agile and riskinformed. 23

24 Implementation Tiers - Selection During the Tier selection process, an organization should consider its current risk management practices, threat environment, legal and regulatory requirements, business/mission objectives, and organizational constraints. The Framework Implementation Tiers are not intended to be maturity levels. 24

25 Implementation Tiers - Use The Tiers are intended to provide guidance to organizations on the interactions and coordination between cybersecurity risk management and operational risk management. The key tenet of the Tiers is to allow organizations to take stock of their current activities from an organization wide point of view and determine if the current integration of cybersecurity risk management practices is sufficient given their mission, regulatory requirements, and risk appetite. Progression to higher Tiers is encouraged when such a change would reduce cybersecurity risk and would be cost-effective. 25

26 Tools The Framework Core and Informative Requirements are available as separate downloads in three formats: spreadsheet (Excel) alternate view (PDF) database (FileMaker Pro). A companion Roadmap discusses future steps and identifies key areas of cybersecurity development, alignment, and collaboration. The Department of Homeland Security's Critical Infrastructure Cyber Community C³ Voluntary Program helps critical infrastructure owners and operators align with existing resources to assist them in using the Cybersecurity Framework and managing their cyber risks. 26
