What is NIST CSF?
The NIST Cybersecurity Framework (CSF) is a risk management framework developed by the US National Institute of Standards and Technology that organizes security activities into five core functions: Identify, Protect, Detect, Respond, and Recover.

- The NIST Cybersecurity Framework (CSF) is a risk management framework developed by the US National Institute of Standards and Technology that organizes security activities into five core functions: Identify, Protect, Detect, Respond, and Recover.
How NIST CSF Works
First published in 2014 for critical infrastructure protection, NIST CSF has become widely adopted across industries and internationally. CSF 2.0 (2024) added a sixth function (Govern) and expanded scope.
The five original functions represent a complete security lifecycle: Identify (understand risk context: assets, threats, vulnerabilities), Protect (implement safeguards: access control, training), Detect (identify security events: monitoring, anomaly detection), Respond (act on incidents: response planning, communications, mitigation), Recover (restore capabilities: recovery planning, improvements).
Each function breaks into categories and subcategories with implementation guidance. The framework includes maturity tiers (Partial, Risk-Informed, Repeatable, Adaptive) and profiles describing current versus target security posture. NIST CSF is commonly used for board-level reporting, gap assessments, and regulatory alignment.
NIST CSF in SOC Operations
SOC operations sit primarily in the Detect and Respond functions. Understanding the framework helps you communicate your work to executives and auditors using a common language. The Detect function's subcategories map directly to SOC capabilities: continuous monitoring, anomalies and events detection. The Respond function maps to incident response workflows you execute daily.
