1 Framework for Improving Critical Infrastructure Cybersecurity May 2017

2 Why Cybersecurity Framework? Cybersecurity Framework Uses Identify mission or business cybersecurity dependencies Align and de-conflict cybersecurity requirements Prioritize cybersecurity outcomes Organize, authorize, task, and track work Express risk disposition Understand gaps between current and target 2

3 The Cybersecurity Framework... Includes a set of standards, methodologies, procedures, and processes that align policy, business, and technological approaches to address cyber risks. Provides a prioritized, flexible, repeatable, performancebased, and cost-effective approach, including information security measures and controls, to help owners and operators of critical infrastructure identify, assess, and manage cyber risk. Identifies areas for improvement to be addressed through future collaboration with particular sectors and standards-developing organizations. Is consistent with voluntary international standards. 3

4 The Framework Is for Organizations Of any size, in any sector in (and outside of) the critical infrastructure. That already have a mature cyber risk management and cybersecurity program. That don t yet have a cyber risk management or cybersecurity program. Needing to keep up-to-date managing risks, facing business or societal threats. In the federal government, too since it is compatible with FISMA requirements and goals. 4

5 Cybersecurity Framework Components Aligns industry standards and best practices to the Framework Core in a particular implementation scenario Cybersecurity activities and informative references, organized around particular outcomes Supports prioritization and measurement while factoring in business needs Framework Profile Framework Core Enables communication of cyber risk across an organization Framework Implementation Tiers Describes how cybersecurity risk is managed by an organization and degree the risk management practices exhibit key characteristics 5

6 Implementation Tiers Risk Management Process Integrated Risk Management Program External Participation Partial Risk Informed Repeatable Adaptive The functionality and repeatability of cybersecurity risk management The extent to which cybersecurity is considered in broader risk management decisions The degree to which the organization benefits my sharing or receiving information from outside parties 6 6

7 Core Cybersecurity Framework Component Senior Executives Broad enterprise considerations Abstracted risk vocabulary Specialists in Other Fields Specific focus outside of cybersecurity Specialized or no risk vocabulary Implementation/ Operations Deep technical considerations Highly specialized vocabulary 7

8 Core Cybersecurity Framework Component What processes and assets need protection? What safeguards are available? What techniques can identify incidents? What techniques can contain impacts of incidents? What techniques can restore capabilities?

10 Profile Cybersecurity Framework Component Ways to think about a Profile: A customization of the Core for a given sector, subsector, or organization. A fusion of business/mission logic and cybersecurity outcomes. Identify Protect Detect Respond Recover An alignment of cybersecurity requirements with operational methodologies. A basis for assessment and expressing target state. A decision support tool for cybersecurity risk management. 10

11 Building a Profile A Profile Can be Created in Three Steps 1 Mission Objective A B C Cybersecurity Requirements Legislation Regulation Internal & External Policy Best Practice Subcategory Operating Methodologies 2 3 Guidance and methodology on implementing, managing, and monitoring 11

12 Framework 7-Step Process Step 1: Prioritize and Scope Step 2: Orient Step 3: Create a Current Profile Step 4: Conduct a Risk Assessment Step 5: Create a Target Profile Step 6: Determine, Analyze, and Prioritize Gaps Step 7: Implementation Action Plan 12

17 Key Attributes It s voluntary Is meant to be customized. It s a framework, not a prescriptive standard Provides a common language and systematic methodology Does not tell an organization how much cyber risk is tolerable, nor provide the one and only formula for cybersecurity. Enable best practices to become standard practices for everyone It s a living document Can be updated as stakeholders learn from implementation Can be updated as technology and threats changes. It s broadly applicable All size organizations; all maturities of risk practices; both inside and outside of critical infrastructure; industries, governments, and academia 17

23 Continued Improvement of Critical Infrastructure Cybersecurity Amends the National Institute of Standards and Technology Act (15 U.S.C. 272(c)) to say: on an ongoing basis, facilitate and support the development of a voluntary, consensus-based, industry-led set of standards, guidelines, best practices, methodologies, procedures, and processes to cost-effectively reduce cyber risks to critical infrastructure Cybersecurity Enhancement Act of 2014 (P.L ) 18 December

24 Basics about the Proposed Revision to Framework Draft Cybersecurity Framework Version 1.1 Draft Version 1.1 of the Cybersecurity Framework seeks to clarify, refine, and enhance the Framework The Framework remains flexible, voluntary, and cost-effective The update is fully compatible with V1.0 Updates were derived from feedback NIST received since publication of Cybersecurity Framework Version 1.0 A 90 day public comment period for the version 1.1 draft ended April 10 th, 2017 There will be a Workshop May 16-17, 2017 to continue discussion 24

25 Input to the Framework Update Draft Cybersecurity Framework Version 1.1 The Update was based on feedback from the cybersecurity community including: December 2015 request for information Lessons learned from Framework use Shared resources from industry partners April 2016 Cybersecurity Framework workshop Advances made in areas identified in the Roadmap issued with the Framework in February

26 Major Themes from Inputs Draft Cybersecurity Framework Version 1.1 Several major themes were identified and considered during the update which included: Strengthening authentication & identity management in the Framework Core Guidance for acquisition and supply chain risk management (SCRM) Methodology for measurement and generating metrics Clarity on Implementation tiers and their relationship to profiles 26

27 Cyber Supply Chain Risk Management (SCRM) Overview Draft Cybersecurity Framework Version 1.1 The most notable changes in the draft update related to SCRM Section 3.3 now explains role of SCRM in cybersecurity Multiple provisions were added, including a new category in the Framework Core 27

28 Implementation Tiers and Profiles Draft Cybersecurity Framework Version 1.1 Additional language added on use of Framework Tiers to include prioritization within target Profile and to inform progress in addressing Profile gaps Language added to reflect integration of Framework considerations within organizational risk management programs Tiers have been expanded to include cyber SCRM considerations Figure 2.0 updated to include actions from the Framework Tiers 28

29 Identity Management Draft Cybersecurity Framework Version 1.1 Language of the Access Control category refined to better account for authorization Subcategory on identity proofing (PR.AC-6) added to the Access Control category Access Control category renamed to Identity Management, Authentication and Access Control (PR.AC) to better represent Category and Subcategories scope 29
