Comprehensive and Detailed Explanation (aligned to ISACA CRISC guidance) Log monitoring and security trend analysis provide visibility into changes in the threat landscape and control effectiveness. From a CRISC perspective, the most valuable outcome of trend review is identifying emerging risk scenarios-patterns of events, anomalies, or repeated alerts that signal new attack vectors, control bypasses, or increased threat activity. Recognizing these trends early allows the organization to adjust controls, update risk assessments, and revise scenarios before major incidents occur. While process weaknesses can be discovered through logs and performance can be indirectly assessed, these are secondary benefits. Simply reviewing trends does not in itself confirm that risk is at acceptable levels; that requires a broader comparison to risk appetite and KPI/KRI thresholds. The primary strategic value is early detection and understanding of new or evolving risks.
