ISC2 CC Business Continuity, DR & Incident Response Practice Question
According to the NIST 800-61 incident response lifecycle, after containment and eradication have been performed, what is the next phase?
⚠ Common exam trap
ISC2 often tests the exact NIST 800-61 phase order, and the trap here is that candidates confuse 'Post-incident activity' as the immediate next step after eradication, when in fact Recovery must occur first to restore operations before conducting the final review.

Correct answer & explanation
✓
Recovery
According to the NIST 800-61 incident response lifecycle, the phases are Preparation, Detection & Analysis, Containment/Eradication, and Recovery. After containment (isolating the threat) and eradication (removing malware, patching vulnerabilities), the next phase is Recovery, where systems are carefully restored to normal operations, often using clean backups and verifying system integrity before reconnecting to the network.
