Security+ ยท 4.0 Security Operations
Incident response lifecycle
The standardized workflow for handling a security incident: **Preparation Identification Containment Eradication Recovery Lessons learned** (NIST SP 800-61 or the SANS PICERL variant).
How this shows up at NCAE
When red team plants a backdoor: **Identify** (hunt-script finds it), **Contain** (kill process, block IP), **Eradicate** (remove the cron/service), **Recover** (restore from backup), **Lessons learned** (log what happened). DCWF 531 is named after this lifecycle.
