Five Things to Know About the NIST CSF 2.0
The National Institute of Standards and Technology’s (NIST) Cybersecurity Framework (CSF) is undergoing a major update. Originally released in 2014, the NIST CSF is one of the most widely used cybersecurity frameworks helping organizations understand and manage their cybersecurity risk. NIST is currently updating the CSF to align with the latest cybersecurity trends and best practices, with the expected release date of the CSF 2.0 slated for the first quarter of 2024. NIST recently held a workshop covering proposed changes coming in 2.0. This article will cover the top five things to know about the upcoming NIST CSF 2.0.
What is the NIST CSF?
The NIST CSF was first created in 2014 in response to an Executive Order mandating increased cybersecurity of the nation’s critical infrastructure. Since then, the framework has been voluntarily adopted—or mandated for adoption by such regulations as New York State Education Law 2-d—by organizations of all sizes and in all industries. The framework is organized according to five Functions that define the high-level practices of any cybersecurity program: Identify, Protect, Detect, Respond, and Recover. Within those five Functions are a total of 108 “subcategories,” or discrete control-like statements that define the practices organizations should consider when assessing their own cybersecurity program. The NIST CSF is designed to be vendor agnostic and scalable. It is also non-prescriptive: the NIST CSF is a tool to be used, not a checklist to be followed.
NIST has shared several proposed changes to the CSF in an attempt to make it more useful and aligned with the latest best practices. While the core structure of the NIST CSF is expected to stay the same, several of the proposed changes are promising enhancements to the framework.
Five Things to Know About 2.0
1. A New Governance Function
The NIST CSF is most commonly associated with its five color-coded Functions: Identify, Protect, Detect, Respond, and Recover. For 2.0, NIST is planning to include a sixth Function: Govern. Surely much to the chagrin of graphical design teams that will have to update CSF-related visuals to include this new Function, NIST proposes including the Govern function to emphasize the importance of “cybersecurity risk management governance outcomes.” Many of the categories currently in the Identify Function, such as Business Environment (ID.BE), Governance (ID.GV), and Risk Management Strategy (ID.RM), could be moved to the new Govern Function. The intent for this change is to highlight the importance for any cybersecurity program to develop appropriate policies and procedures, assess and prioritize risk, and clearly define roles and responsibilities.
2. Expanding Supply Chain Risk Management
In 2018 NIST added the Supply Chain Risk Management (ID.SC) category to the CSF. NIST plans to offer even more attention to Cybersecurity Supply Chain Risk Management (C-SCRM) in CSF 2.0. NIST hasn’t provided specifics for how 2.0 would expand coverage of supply chain risk management, but they outline several scenarios, such as creating an entirely new Function devoted to supply chains, spreading more C-SCRM controls across the entire CSF, or expanding the ID.SC category. Regardless, as technology services are increasingly complex, outsourced, and interdependent, there is a greater need for organizations to assess and manage their supply chain risks.
3. New Implementation Guidance for Subcategories
The NIST CSF is meant to be high-level and scalable to any organization. While this provides the benefit of the CSF being a highly adaptable framework, it can also lead to the frustration of the CSF feeling too vague or that the intent behind the subcategories is difficult to discern. For 2.0, NIST is planning to offer a small number of “concise, action-oriented processes” that could help an organization know how to achieve the intended outcome of the subcategory. These “notional implementation examples” are already present in some of the newest NIST frameworks, such as the Secure Software Development Framework. These guideances offer promising opportunities to improve outcomes for users of the CSF.
4. Providing Measurement Examples for the NIST CSF
For many users of the NIST CSF, one of the most frustrating experiences is tracking “compliance” with the CSF and measuring the evolution of one’s cybersecurity program over time against the CSF. NIST is transparent that this issue will not be solved with CSF 2.0. Their reasoning is “Because there is no single approach to measure and assess the CSF, NIST will not put forward a single approach to assessment in the CSF 2.0 in order to continue flexibility in how organizations may implement the Framework.” However, NIST does say 2.0 will include examples of how other organizations have used risk management frameworks and maturity models to assess their CSF capabilities. Additionally, NIST encourages community input on draft SP 800-55r2, the Performance Measurement Guide for Information Security (https://csrc.nist.gov/publications/detail/sp/800-55/rev-2/draft). Until —or if—NIST publishes a formal CSF assessment model it’s up to each organization to use a measurement schema that works best for them.
5. More Informative References
The NIST CSF is one of many popular cybersecurity frameworks, such as NIST 800-53, ISO/ISEC 27001, CIS Controls, and COBIT 2019. The CSF has always provided an informative references section that maps each CSF subcategory to other popular frameworks. For 2.0, NIST promises to update the informative references section to align with the latest mappings along with providing the most up-to-date and searchable mappings in their Online Informative References Program (OLIR). The OLIR is a recent NIST resource that already provides several exportable and sortable spreadsheet mappings between the CSF and other popular frameworks. NIST promises the expansion and continual update of OLIR with the release of the CSF 2.0.
