Incident Response: Triage to Recovery
Follow a structured incident-response workflow from initial validation through containment, recovery and lessons learned.
QUICK READ
Incident response is a controlled process. The analyst should preserve evidence, scope the activity, coordinate containment and document decisions according to authorized procedures.
Use this page after the daily quiz: learn the concept first, then follow the investigation workflow and examples.
Triage questions
- What happened?
- Which accounts and systems are involved?
- When did it start?
- How confident are we?
- What evidence is available?
- What is the potential impact?
Containment considerations
Containment should be proportionate and authorized. Options can include account controls, endpoint isolation, network restrictions or blocking indicators depending on the incident and procedures.Recovery
Validate that the root cause or access path has been addressed, restore affected services safely, monitor for recurrence and document the outcome.Common mistakes
- Taking disruptive action before scoping when evidence can be preserved safely.
- Failing to document decisions.
- Closing the case without lessons learned.
Daily quiz hook
During an incident, why should an analyst establish scope before making broad containment decisions when circumstances allow?

Analyst practice note
Incident response moves from preparation and detection through analysis, containment, eradication, recovery, and lessons learned. The order and authority for actions depend on organizational policy, business impact, evidence needs, and incident scope.
Use the ransomware simulation to distinguish immediate containment from eradication and recovery. Preserve relevant evidence, coordinate with system owners, and validate backups and restored services before declaring recovery complete.
