NIST Cybersecurity Framework 2.0: What’s New?

Authors: Steve Foret | Mark Keppler

Quick answer: CSF 2.0 adds Govern, broadens its audience, and sharpens supply chain risk management. Start by comparing your Current and Target Profiles and prioritizing gaps by business risk.

Cybersecurity Frameworks Series, part 3

NIST released Cybersecurity Framework (CSF) 2.0 on February 26, 2024, following version 1.1 in 2018. The update explicitly serves organizations of all sizes and sectors, adds the Govern function, and strengthens attention to cybersecurity supply chain risk. It provides outcomes for managing risk rather than a prescribed control checklist.

What are those big changes?

The new Govern function brings strategy, accountability, policy, oversight, and supply chain risk management into clearer focus. The six functions—Govern, Identify, Protect, Detect, Respond, and Recover—work together. Governance connects security decisions to business objectives and risk tolerance.

Second, there is a renewed focus on software and vendor security activities, “Supply Chain”, and self-contained technology (internet of things “IoT”). This focus existed in the prior versions but, over past decade, these elements have become key challenges to maintaining secure environments. There is intentional focus on tightening controls and insight into the complex activity of development, data protection, and integrated capabilities with third parties.

The third, and final, theme is renewed focus on defensive security technology management and operational procedures to improve vulnerability threat management, incident response, and recovery (not just detection). This incorporates enhanced technology, designs assessment, insight management, threat management, and ongoing breach mitigation assessments to verify defensibility in a programmatic way.

With these 2.0 enhancements, businesses will need to review and update their policies and procedures, align technical requirements to operating service capabilities, and review roles and responsibilities in-house and with external partners to adjust accountability and delivery quality. In many organizations, these enhancements may require both internal assistance and external partnerships throughout the business and technology teams.

And the specific changes?

A breakdown of some of the more tactical changes has been included below in a consolidated list of critical tasks:

Clarify and define cybersecurity to the business itself for stronger oversight, accountability, and reporting.
Gain clarity on lines of separation of duties (Operate, Risk/Govern, Audit) to improve confidence.
Document applicable incident-reporting obligations, deadlines, decision owners, and escalation channels. CSF 2.0 does not itself impose a universal four-day breach-reporting deadline.
Clearly define what is Risk, a Breach, and “Significant Breach” for the organization.
Emphasize defining the cybersecurity services model.
Leverage more proactive data protection tactics related to inventory, discovery and management of systems and data.
Expand the definition of dependency management to the organization by reviewing supply chain and risk analysis of what is being supplied to organization (Data, Management, Transformation, Software, etc.).
Expand threat intelligence, event detection and respond/recovery cybersecurity management and operating functions.
Better document and proactively manage technology resiliency and trust boundaries with vendors, risky employees, and systems.
Improve integration of systems and event data as part of the normal technology lifecycle.
Expand third party management into all aspects of business partnering.
Expand continuous monitoring with more self-assessment and management reporting.

So What: What do these new features mean to those aligned to prior versions?

This is an appreciable update that will require a brief gap analysis of how practices in cybersecurity, that may not have been documented or aligned within prior CSF version, can now align, in conjunction with understanding the desired rigor of risk governance and management, using CSF Tiers alongside Current and Target Profiles.

Most public reporting organizations we work or chat with have already worked hard at the larger lens of cybersecurity practices already, meaning they have already tackled a lot of the new requirements even though they are not in the CSF v1.1. Being in this stronger position already, make this a less taxing effort as most organizations have regulatory requirements, emerging technology frameworks or industry specific compliance requirement such as medical devices, energy sectors, credit cards, or external forces pushing the needs. So, there is a good chance most organizations align in the day to day, and this is a potentially a governance maturation and alignment exercise.

How about for those who have not used a cybersecurity standard in their organization. How long does it take, what are the key activities, what do you prioritize?

Like any business initiative you need to establish a goal of transformation of the business as this typically forces complex discussions. There will ultimately be a set of tasks to accomplish such a monumental undertaking. To step the basic strategy:

Understand and select a cybersecurity framework (CSF 2.0 in this scenario) target that fits your industry/regulatory requirements.
Assess your current state against the standard to determine what you already have in place.
Create action plans to establish cybersecurity pillars for the organization, technology goals, people goals, and process goals.
Set organization roadmap with goals and objectives to accomplish the gaps.
Set risk terminology, maturity states for the roadmap and action plan.
Create or incorporate governance to a leadership team that will maintain sponsorship, organization resolve, measure, and report on progress, and enable teams to successfully transform the environment.
Implement technology and security practices for management and reportability.
Iteratively improve the governing and operating environment.

There is no fixed NIST implementation timetable. Set achievable milestones based on your starting point, scope, resources, and risk. Begin with an agreed Current Profile, define a Target Profile, and assign owners and dates to the highest-priority gaps.

What are the benefits of this new standard?

The biggest benefit is the continued expansion of what cybersecurity means. Education and awareness are the hardest aspects of cybersecurity. As a business owner, salesman, product manager, call rep, or accountant, this standard is talking at a more consumable level where everyone can add value. This demystification of cybersecurity with these newer standards continues to expose complicated topics in simpler terms.

As a regular technology user, manager, or leader, how do I support the cause without having a huge impact on my teams?

Maintain a commonsense user, data, and process management space. If you know what roles you have on the team, what data or applications are required, and which key business processes are being supported, you’ve answered the hardest part.

Maintain a touchpoint with your cybersecurity leaders (managers, directors, etc) and keep them updated on what your team or business process is doing and what changes may be coming up in the next 6-12 months.

Review how you and your team interface with cybersecurity in case there ever is a need to engage.

More specifically to a technology team, while you operate your own technology standards and practices, provide cybersecurity with access to data outputs, design and deploy technology, running guidelines, and ticketing and reporting systems. There will be scenarios where technologies overlap, intersect, and work in conjunction with each other.

Frequently asked questions

What is the biggest change in NIST CSF 2.0?

The new Govern function makes cybersecurity strategy, policy, accountability, oversight, and supply chain risk more explicit alongside the five existing functions.

Does CSF 2.0 require breach reporting within four days?

No. CSF 2.0 does not impose a universal four-day reporting deadline. Organizations must identify the separate laws, regulations, and contractual obligations that apply to their incidents.

Is CSF 2.0 a certification or a mandatory control checklist?

No. It is an outcomes-based risk management framework. Organizations choose how to achieve relevant outcomes and map them to their circumstances and applicable requirements.
