Glossary / NIST Cybersecurity Framework (CSF)

NIST Cybersecurity Framework (CSF)

To help organizations manage and mitigate cybersecurity risks, the National Institute of Standards and Technology (NIST) developed the Cybersecurity Framework (CSF), a valuable and flexible set of guidelines for improving cybersecurity posture.

What is the NIST CSF?

The NIST CSF is a voluntary framework that provides a common language and a structured methodology for managing cybersecurity risk. It’s designed to be adaptable to organizations across various sectors, from healthcare and finance to government and education. 

At its core, the framework is built on five key functions:

  • Identify: Understanding your assets, systems, and data, and assessing the potential risks they face.
  • Protect: Implementing safeguards to limit or contain the impact of a cybersecurity event. This includes access control, data security, and protective technologies.
  • Detect: Identifying cybersecurity events as they occur through continuous monitoring and threat intelligence.
  • Respond: Developing and implementing plans to effectively manage incidents, mitigate damage, and contain the impact.
  • Recover: Restoring any capabilities or services that were impaired due to a cybersecurity event.

These functions are further broken down into categories and subcategories, providing a granular view of cybersecurity best practices.

NIST CSF 2.0: What’s new?

The recently updated NIST CSF 2.0 incorporates new insights and addresses evolving cyber threats. Key changes include:

  • Emphasis on cybersecurity governance: CSF 2.0 strengthens the focus on governance, emphasizing risk management, asset management, and supply chain risk management (C-SCRM).
  • Alignment with privacy: The updated framework better integrates privacy considerations into cybersecurity practices.
  • Clarified guidance: CSF 2.0 provides clearer guidance on implementation tiers, profiles, and self-assessment.

Enhancing the NIST Cybersecurity Framework with Identity Continuity

Implementing the NIST CSF

The NIST CSF is not a one-size-fits-all solution. Organizations can tailor its implementation based on their specific needs, risk tolerance, and resources. This is where the concept of “Implementation Tiers” comes into play. Ranging from Partial (Tier 1) to Adaptive (Tier 4), these tiers represent the level of cybersecurity sophistication within an organization.

To further customize the framework, organizations can create “profiles” that align the CSF with their unique requirements and risk profiles. These profiles serve as a roadmap for improving an organizatoin’s cybersecurity posture and identifying gaps in existing practices.

Benefits of using the NIST CSF

The NIST Cybersecurity Framework (CSF) brings many advantages to organizations striving to enhance their cybersecurity efforts. Here are some key benefits:

  • Lower cybersecurity risks: Following the framework’s guidance helps organizations bolster their defenses and reduce exposure to potential cyber threats.
  • Better communication and teamwork: The CSF creates a shared understanding of cybersecurity concepts, making it easier for teams to collaborate and communicate effectively.
  • Stronger resilience: By focusing on preparation and response, the framework enables organizations to handle cybersecurity incidents more effectively, ensuring minimal disruption to operations.
  • Support for compliance: Although adopting the CSF is optional, it aligns well with various industry regulations and standards, helping organizations achieve and maintain compliance.

In short, the NIST CSF is a practical tool for building a robust cybersecurity strategy that supports both operational success and regulatory needs.

Where to find help with the NIST Cybersecurity Framework

There are plenty of resources available to make implementing the NIST CSF easier:

  • NIST’s website: This is the go-to spot for the complete framework, along with helpful templates, tools, and step-by-step guidance.
  • NIST special publications: These dive into specific topics like risk assessments (check out NIST SP 800-30) and how to handle incidents (NIST SP 800-61).
  • Third-party support: Many companies offer training, consulting services, and tools to help you get started or improve your framework implementation.

Staying on top of updates — like the new CSF 2.0 — can help you tackle cybersecurity challenges head-on and keep your digital assets secure.
