Episode 43 — System and Communications Protection — Part Three: Evidence, coverage, and pitfalls
Evidence for system and communications protection confirms that segmentation, encryption, and traffic controls function as designed. For the exam, candidates must know that sufficient evidence includes firewall configurations, packet capture samples, key rotation records, and network diagrams showing logical boundaries. Coverage checks verify that every communication path, including management and backup channels, is protected appropriately. Common pitfalls include incomplete diagrams, unlogged rule changes, or outdated certificates that silently weaken trust. Another frequent issue arises when evidence reflects configuration intent but not operational behavior—logs show blocked traffic, but live tests reveal open paths. Reliable evidence must therefore combine documentation with validation.
In real operations, continuous monitoring tools collect data on encryption status, protocol versions, and boundary device performance. Automated checks detect expired certificates, weak ciphers, or unencrypted endpoints before audits expose them. Coverage reviews ensure that new services inherit required protections rather than bypassing them. When anomalies appear, corrective actions are documented with before-and-after evidence to prove closure. Avoiding pitfalls requires keeping both human review and automated testing in sync. Professionals who manage this balance show that security controls are more than configurations—they are living mechanisms verified through data, discipline, and accountability.
