Episode 25 — Monitor logs with intent and respond to signals
Logging is only valuable when it answers who did what, where, and when, with enough context to judge impact, so the exam stresses purposeful coverage over raw volume. This episode defines an exam-ready logging strategy: select critical events across authentication, authorization, configuration changes, network rules, and application actions that touch payment processes; synchronize time so correlation holds; and protect logs from tampering with write-once or restricted access paths. You should recognize evidence that monitoring works—alerts reaching a ticketing or incident platform, dashboards that track baselines and anomalies, and sample investigations that link events across systems. Retention and scope matter, too; logs from in-scope systems and those that can affect their security must be collected, and storage must align with policy and legal needs.
Response closes the loop. We translate signals into decisions: repeated failed admin logins from odd geolocations warrant lockout and review, configuration changes outside approved windows require rollback and root-cause analysis, and denied firewall traversals that spike after a new vendor connection suggest misconfigured routes or probing. Troubleshooting covers noisy rules that hide true anomalies, agents that silently fail, and blind spots like SaaS platforms where API exports are needed to capture activity. The exam favors answers that balance detection with action: tuning rulesets, sampling logs for integrity, testing alert flows with drills, and documenting outcomes so lessons feed back into configuration and access controls. Choose options that transform events into verifiable investigations and improvements, with artifacts that prove both the signal and the response.
