Log Analysis and Anomaly Detection Questions

Interpreting and investigating system and security logs to detect suspicious patterns, operational issues, and potential incidents. This covers understanding different log types such as firewall, web server, application, and system event logs, log parsing and aggregation, constructing queries and alerts, pattern matching and anomaly detection, distinguishing false positives from true incidents, correlating events across sources, and supporting incident response and root cause analysis. Candidates should demonstrate how to extract relevant signals, define baselines, tune detection rules, and communicate findings including prioritized remediation steps.
