post-incident-analysis

Post-incident analysis in ServiceNow is performed by loading a closed security incident into a PIR workflow, which gathers data from incident records, work notes, and audit history to generate a formal report. It uses MCP and REST interfaces to assemble and verify findings.

Reconstructing an incident timeline is best achieved by extracting chronological data from audit history and work notes to reveal the exact sequence of events. This process identifies detection and response gaps to produce actionable lessons learned.

Calculating time to detect, triage, contain, eradicate, and recover is done by analyzing the timestamps in incident records and audit logs within the PIR workflow. This calculation generates actionable improvement recommendations for future response efforts.

The post-incident analysis workflow operates without external dependencies, relying entirely on native ServiceNow Security Operations data. It uses MCP and REST interfaces to gather incident records, work notes, audit history, and tasks to verify findings.

Generating executive summaries and lessons-learned documentation is a core feature of the PIR workflow applied to closed ServiceNow incidents. It automatically formats root-cause documentation and improvement recommendations for management and compliance review.
