Individual skill
triaging-security-incident
Performs initial triage of security incidents to determine severity, scope, and required response actions using the NIST SP 800-61r3 and SANS PICERL frameworks. Classifies incidents by type, assigns priority based on business impact, and routes to appropriate response teams. Activates for requests involving incident triage, security alert classification, severity assessment, incident prioritization, or initial incident analysis.

# Triaging Security Incidents
## When to Use
- A SIEM or EDR alert fires and requires human classification before escalation
- Multiple concurrent alerts arrive and the SOC must prioritize response order
- An end user reports suspicious activity and the incident needs initial categorization
- A threat intelligence feed matches an IOC observed in the environment
**Do not use** for routine vulnerability scanning results or compliance audit findings that do not represent active security incidents.
## Detection Gaps & Validation
- **The most-missed triage error is closing an alert in isolation:** before declaring a true/false positive, pivot on the same host, user, and hash across the prior 30 days. An "isolated" encoded-PowerShell or quarantined-malware alert is often one stage of a larger chain (initial access → persistence → lateral movement) that single-alert triage hides.
