Understanding NIST CSF
The NIST Cybersecurity Framework (CSF) was originally developed in 2014 in response to an executive order from President Obama and has since become the most widely adopted cybersecurity framework in the United States. NIST CSF 2.0, released in 2024, expanded the framework with a sixth core function (Govern) and broadened its applicability beyond critical infrastructure to all organizations.
Unlike compliance-focused frameworks like SOC 2 or PCI-DSS, NIST CSF is a risk management framework. It does not prescribe specific controls but provides a structure for understanding, managing, and communicating cybersecurity risk. Organizations use it to assess their current security posture, define a target state, and create a prioritized roadmap for improvement.
NIST CSF is frequently used as the organizational backbone of a security program, with specific compliance requirements (SOC 2, HIPAA, PCI-DSS) mapped to its functions and categories. This approach provides a unified view of security posture across multiple compliance requirements.
The Six Core Functions
Govern
Establish and monitor the organization's cybersecurity risk management strategy, expectations, and policy. (New in CSF 2.0)
Identify
Understand the organization's assets, risks, and business context to prioritize cybersecurity efforts.
Protect
Implement safeguards to ensure delivery of critical services including access control, training, and data security.
Detect
Develop and implement activities to identify the occurrence of cybersecurity events in a timely manner.
Respond
Take action regarding a detected cybersecurity incident to contain impact and support recovery.
Recover
Maintain plans for resilience and restore any capabilities impaired by a cybersecurity incident.
