Triaging Security Incidents with IR Playbooks

When to Use

• New security alert received from SIEM, EDR, or other detection sources
• SOC analyst needs to determine if an alert is a true positive requiring response
• Incident needs severity classification and team assignment
• Multiple concurrent incidents require prioritization
• Automated triage rules need validation or tuning

Prerequisites

• SIEM platform with alert correlation (Splunk, Elastic, QRadar, Sentinel)
• Incident response playbook library (by incident type)
• Severity classification matrix approved by CISO
• On-call rotation and escalation procedures
• Ticketing system for incident tracking (ServiceNow, Jira, TheHive)
• Threat intelligence feeds for IOC enrichment
