The NIST Cybersecurity Framework (CSF) is a set of standards and guidelines for managing and protecting critical infrastructure. It provides a common language and approaches for organizations to manage and reduce cybersecurity risk. The framework is designed to be flexible and adaptable, so organizations can tailor their approach to meet their specific needs and constraints. The key components of the NIST CSF include the following:

1. Identifying, Protecting, Detecting, Responding, and Recovering from cyber-attacks.
2. Providing a structured approach to managing and reducing cybersecurity risk by aligning with business drivers and processes.
3. Providing a common language for discussing cybersecurity risk and informing decision-making.
4. Supporting collaboration among organizations, sectors, and government to share information and coordinate responses to cyber threats.

The NIST CSF provides a risk-based approach to cybersecurity, and organizations can use it to identify and prioritize areas for improvement. It can also be used to assess the effectiveness of existing cybersecurity practices and to support continuous improvement. The NIST CSF is widely adopted by public and private organizations and is considered a best practice for managing and reducing cybersecurity risk.

    NIST has revised the framework to help benefit all sectors, not just critical infrastructure. After considering more than a year’s worth of community feedback, the National Institute of Standards and Technology (NIST) has released a draft version of the Cybersecurity Framework (CSF) 2.0, a new version of a tool it first released in 2014 to help organizations understand, reduce and communicate about cybersecurity risk. The draft update, which NIST has released for public comment, reflects changes in the cybersecurity landscape and makes it easier to put the CSF into practice — for all organizations.

    NIST Cybersecurity Framework (CSF) 2.0 (Draft)

    The CSF 2.0 draft reflects a number of major changes, including:

28. The framework’s scope has expanded — explicitly — from protecting critical infrastructure, such as hospitals and power plants, to providing cybersecurity for all organizations regardless of type or size. This difference is reflected in the CSF’s official title, which has changed to “The Cybersecurity Framework,” its colloquial name, from the more limiting “Framework for Improving Critical Infrastructure Cybersecurity.”
29. Until now, the CSF has described the main pillars of a successful and holistic cybersecurity program using five main functions: identify, protect, detect, respond, and recover. To these, NIST now has added a sixth, the govern function, which covers how an organization can make and execute its own internal decisions to support its cybersecurity strategy. It emphasizes that cybersecurity is a major source of enterprise risk, ranking alongside legal, financial, and other risks as considerations for senior leadership.
30. The draft provides improved and expanded guidance on implementing the CSF, especially for creating profiles that tailor the CSF for particular situations. The cybersecurity community has requested assistance in using it for specific economic sectors and use cases where profiles can help. Importantly, the draft now includes implementation examples for each function’s subcategories to help organizations, especially smaller firms, to use the framework effectively.
