A Security Operations Center (SOC) team is deploying an automated Security Orchestration, Automation, and Response (SOAR) playbook to address high-risk suspicious email reports. To prevent accidental disruption to critical business communications while ensuring rapid response, the automated response workflow must follow strict SOC governance standards spanning ingest, threat intelligence enrichment, analyst review, containment, and post-incident cleanup. In what sequence should the SOAR playbook execute these operational steps?
- 1Ingest alert payloads from the reporting service webhook and parse extracted URL indicators and sender envelope headers.
- 2Query threat intelligence feeds and detonation sandboxes to compute a unified threat score for the parsed indicators.
- 3Evaluate conditional threshold rules and trigger a Human-in-the-Loop (HITL) prompt for analyst authorization.
- 4Issue API requests to Endpoint Detection and Response (EDR) and Identity Provider (IdP) systems to isolate the affected host and revoke active user OAuth tokens.
- 5Update perimeter blocklists with verified indicators, update the SIEM alert status, and close the incident management ticket.
Cevap
The correct operational order begins with alert payload ingestion and IOC parsing, followed by automated threat intelligence enrichment, triggering a Human-in-the-Loop (HITL) approval gate, executing automated host isolation and token revocation upon authorization, and concluding with perimeter blocklist updates and case closure.
In SOAR playbook architecture, incident response follows a structured sequence: initial data ingestion and IOC extraction, automated threat intelligence lookup, decision governance via Human-in-the-Loop (HITL) verification for high-impact remediations, automated execution of containment scripts, and final documentation with blocklist propagation.
