Log analysis is the process of reviewing, interpreting, and understanding computer-generated records. Logs provide valuable information about system events, security incidents, performance issues, and user activities. Security log analysis helps detect intrusions, policy violations, and anomalous behavior. Tools include SIEM platforms, log aggregators (ELK Stack), and command-line utilities (grep, awk). Effective log analysis requires understanding normal behavior patterns and maintaining centralized, tamper-proof log storage.
