NIST Cybersecurity Framework (CSF)

A NIST framework of cybersecurity outcomes organized into six functions: Govern, Identify, Protect, Detect, Respond and Recover.

Definition

CSF 2.0, released in February 2024, added the Govern function and broadened applicability beyond critical infrastructure. Its Detect, Respond and Recover functions frame security operations and incident response activities, and SP 800-61 Rev. 3 is aligned to it.

Example

Mapping SOC monitoring capabilities to the CSF Detect function categories.

Exam tip

CSF 2.0 has six functions; Govern is new in 2.0.
