Episode 20 — Establish Configuration Management Plan

A Configuration Management (CM) Plan defines how changes are proposed, evaluated, approved, implemented, and verified so that security commitments remain intact as the system evolves. This episode outlines the essential elements reviewers expect: defined roles and segregation of duties, standardized change types with risk criteria, impact analysis methods tied to security controls, peer review and approval steps, rollback and contingency provisions, and post-implementation validation. We connect the plan to tangible artifacts—tickets with linked commits, deployment records, test results, and sign-offs—because assessors rely on these to confirm the process operates as written. The plan should also address emergency change handling and traceability from requirement to production while preserving evidence for later audits.

We extend the plan into daily practice and continuous monitoring. Integrate CM with your vulnerability and patch cadence, ensuring authenticated scans and configuration baselines detect and report drift introduced by changes. Align change windows with assessment activities so scans and penetration tests occur against representative states, not transient ones. Automate as much as feasible—policy-as-code checks, static analysis gates, configuration drift alerts—and record outcomes in a way that is easy to sample and verify. When significant changes are proposed, trigger security impact reviews, update boundary and interconnection documentation, and notify reviewers according to FedRAMP expectations. A mature CM plan anchors predictable, auditable change, reducing authorization risk while enabling the system to improve safely.
