Episode 39 — System and Information Integrity — Part Three: Evidence, signals, and pitfalls
Evidence of system and information integrity proves that protective measures function consistently and effectively. For the exam, candidates must identify credible sources of such evidence: vulnerability reports, malware scan results, change logs, and alert histories. These records confirm that systems detect anomalies and respond as documented. Signals—such as sudden log changes, configuration drift, or spikes in endpoint detections—serve as indicators of potential compromise or failure. Proper analysis links these signals back to controls to confirm effectiveness. Pitfalls arise when evidence is incomplete, outdated, or stored without context, making it impossible to verify response timeliness or coverage.
Operationally, mature organizations integrate evidence collection into automated workflows so that every detection event is logged, categorized, and tied to remediation. Dashboards visualize signals, helping analysts separate routine noise from genuine threats. Post-incident reviews examine whether alerts were detected, triaged, and resolved within expected timeframes, producing data for continuous improvement. Avoiding pitfalls requires disciplined documentation of every integrity event—from initial discovery to final verification—ensuring that no step depends solely on memory or informal communication. These practices create a trustworthy audit trail and prove that integrity controls deliver measurable protection.
