NIST Cybersecurity Framework

NIST CSF is a voluntary framework providing guidance on managing cybersecurity risk, organized around five core functions: Identify, Protect, Detect, Respond, and Recover.

The NIST Cybersecurity Framework (CSF) is a set of guidelines and best practices developed by NIST to help organizations manage cybersecurity risk.

The five core functions: 1. Identify: Understand your environment—assets, risks, governance 2. Protect: Implement safeguards—access control, training, data security 3. Detect: Discover security events—monitoring, detection processes 4. Respond: Take action—response planning, communications, analysis 5. Recover: Restore capabilities—recovery planning, improvements

NIST CSF 2.0 (2024) added: - Govern: Organizational context for managing risk - Updated profiles and implementation tiers - Enhanced supply chain risk guidance

Benefits of NIST CSF: - Framework is free and widely respected - Risk-based approach adaptable to any organization - Maps to other standards (ISO 27001, SOC 2) - Provides common language for security discussions

Why It Matters

NIST CSF is the most widely adopted cybersecurity framework in the US, referenced in federal executive orders, insurance requirements, and enterprise vendor questionnaires. Its risk-based approach and mapping to other frameworks make it an excellent starting point for organizations building their first security program. The framework is free, flexible, and provides a common language that bridges technical security teams and business leadership.
