Episode 25 — Configuration Management — Part One: Baselines, change control, and integrity
Configuration management defines how systems maintain secure, consistent, and verifiable states over time. In NIST 800-53, configuration controls ensure that every system component is deployed and maintained according to approved baselines. Exam candidates must understand that baselines represent the known, secure configurations from which all changes are measured. Change control processes evaluate and approve modifications before implementation to prevent introducing vulnerabilities. Configuration integrity safeguards detect unauthorized changes and restore systems to approved states. These principles form the backbone of operational assurance and are frequently tested across assessment and authorization activities.
Practically, organizations implement configuration management through tools that monitor system settings, apply patches, and record deviations automatically. Version control repositories store configuration artifacts for traceability, while change advisory boards review proposed updates. Continuous monitoring ensures that deviations are detected promptly and reconciled with baseline definitions. Configuration integrity verification—through hash checks or automated scans—protects against drift, tampering, and configuration sprawl. Mastery of these concepts prepares professionals to explain how stable configurations contribute directly to predictable, resilient operations.
