A Practical Guide to Security Log Analysis, Detection, and Investigation

Summary
The article explains security log analysis workflows, data sources, formats, monitoring, and pattern recognition, then promotes SOC Prime’s LogTotal tool for analyzing and correlating events with privacy safeguards.
Key points
- The article outlines five workflow stages: collection, parsing and normalization, enrichment, correlation, and retention with integrity protections.
- It distinguishes continuous detection, post-alert investigation, and proactive threat hunting as three uses of log analysis.
- Endpoint, identity, network, cloud, application, and security-control logs provide complementary evidence; correlating them can reveal attack sequences.
- Monitoring pipelines can reduce detection delays, but require handling late events, state management, and alert volume.
- Pattern recognition ranges from matching individual events to thresholds, sequence correlation, anomaly detection, and correlating detections into attack chains.
- SOC Prime says LogTotal supports several log formats, correlates detections, and sanitizes data in the browser; its performance and privacy claims are vendor claims.
