🔬 Deep Dive: NIST Cybersecurity Framework
The NIST CSF organizes security into five functions: Identify—asset inventory, risk assessment. Protect—access control, training, data security. Detect—monitoring, anomaly detection. Respond—incident response planning and execution. Recover—backup and recovery planning. Within each function are categories and subcategories with implementation tiers (1-4). It's voluntary, flexible, and widely adopted. Other frameworks: ISO 27001 (certifiable standard), CIS Controls (prioritized list), COBIT (governance-focused), SOC 2 (service organization audits).
