Differences Between the NIST Cybersecurity Framework 1.1 and 2.0

Posted by wgard005 on

Overview

The NIST Cybersecurity Framework (CSF) is a voluntary guidance framework for organizations to manage and reduce cybersecurity risk. Version 2.0, released in 2023, introduces significant updates to align with evolving cybersecurity needs. Below are the primary differences between CSF 1.1 (2018) and CSF 2.0 (2023).

1. Framework Structure and Language 

  • Name Change: The framework is now called the “NIST Cybersecurity Framework” instead of the “NIST Framework for Improving Critical Infrastructure Cybersecurity,” reflecting its broader applicability beyond critical infrastructure sectors.
  • Structure Update: The structure is more modular, with clearer definitions and enhanced guidance for implementing cybersecurity practices across diverse sectors and organizations.
  • This change was needed because of the way the framework was structured. In the 1.1 version of the framework, it was titled “NIST Framework for Improving Critical Infrastructure Cybersecurity”. With this type of title, it makes the people who are reading it think that this framework is only meant for critical infrastructures. With the 2.0 framework, the title “NIST Cybersecurity Framework”, it lets the people who are reading it know that it is not only meant for critical infrastructure, but that it can also be used for anything cybersecurity related.

2. Governance as a Core Function

  • New Function Added: The addition of a sixth Core Function, “Govern”, emphasizes the importance of cybersecurity governance. This function includes activities related to developing and managing policies, processes, and legal/regulatory obligations.
  • Govern Function Categories: New categories under “Govern” include governance policies, risk management strategy, roles and responsibilities, and legal and regulatory requirements.
  • This change was necessary because of the addition of the Govern function. In the 1.1 version of the cybersecurity framework, the functions only had recover, identify, respond, protect, recover, and detect. This left a big hole for how the framework was to be enforced. With the 2.0 framework, the govern function fills that hole. The govern function includes things such as enforcement of the framework, and policies that the people in the cybersecurity field should follow.

3. Updates to Categories and Subcategories

  • Improved Alignment: The subcategories have been updated to better align with contemporary cybersecurity practices and technologies.
  • New Subcategories: Some subcategories have been added to address emerging cybersecurity challenges, such as supply chain risk management and secure software development.
  • This update was important because the 1.1 version of the categories and subcategories was outdated. In the 1.1 version, there was no categories for upcoming challenges in the Cybersecurity field, such as the supply chain and software development. With the 2.0 version of the framework, they have added subcategories for those challenges.

4. Enhanced Implementation Guidance

  • Profiles and Implementation Tiers: Revised guidance for creating Profiles and selecting Implementation Tiers provides clearer instructions for customizing the framework to fit an organization’s risk environment and capabilities.
  • Updated Roadmap: The updated CSF roadmap outlines future directions, including potential new areas of focus such as supply chain security and privacy considerations.
  • This change was needed because of new areas of focus. In the 1.1 version of the framework, the roadmap did not include new areas of interest such as supply chain security and privacy. With the 2.0 version, they give focus to such areas. With this, it will let people in the cybersecurity field be more prepared to tackle new threats.

5. Integration with Other Frameworks and Standards 

  • Broader Integration: CSF 2.0 is more integrated with other NIST guidelines and international standards, making it easier for organizations to use it alongside frameworks like ISO/IEC 27001 or the NIST Risk Management Framework (RMF).
  • This update was important because of how much it improved the international use of the framework. With the 2.0 version, the framework is applicable with international infrastructure, compared to the 1.1 version only really being able to work on domestic infrastructure. Also, with the 2.0 version, it will be translated into different languages around the world, while the 1.1 version was in English.

6. Feedback and Community Involvement 

  • Enhanced Community Input: The development of CSF 2.0 involved broader engagement with public and private sector stakeholders, ensuring the framework addresses a wider range of needs and challenges.
  • This change was important because of how much they put into receiving feedback. With the 2.0 version, they allowed more engagement with the business side of the company (investors, etc.). With this, they will be able to change their approach of their security to cover a broader range of important areas.

Summary

The transition from NIST CSF 1.1 to 2.0 reflects a maturation in cybersecurity risk management practices, emphasizing governance, expanding applicability, and providing more robust guidance for organizations globally. These updates make CSF 2.0 a more comprehensive and flexible tool for enhancing cybersecurity resilience.

This synopsis covers the major changes between the two versions while keeping the document concise and accessible.”
