Episode 27 — Configuration Management — Part Three: Evidence, sampling, and pitfalls
Evidence in configuration management proves that baselines are defined, implemented, and enforced. Candidates must recognize that sufficient evidence may include configuration files, system snapshots, scan results, or change logs that show compliance with approved settings. Sampling allows assessors to verify a representative subset of configurations, confirming that implementation is consistent across environments. Common pitfalls include incomplete baselines, missing approval documentation, or reliance on manual reviews that quickly become outdated. NIST 800-53 expects not only initial compliance but sustained control of configuration states throughout the system lifecycle.
In operational environments, configuration management databases or automation dashboards serve as evidence sources. Automated reports can show baseline adherence rates, change approval timestamps, and remediation outcomes. Periodic sampling detects configuration drift and validates monitoring tool accuracy. When discrepancies occur, corrective actions must be documented and tracked to closure to preserve the credibility of the evidence trail. Avoiding pitfalls means ensuring every baseline and modification has verifiable approval and technical proof. Mastery of evidence practices enables professionals to present configuration integrity as both a technical and managerial discipline.
