What you will be able to do
- List the incident lead, backup, and external contacts your plan needs before an incident happens.
- Walk through the five phases: detect and report, triage, contain, eradicate and recover, and review.
- Identify which contractual, regulatory, insurer, and customer notification timelines apply to your organization.
- Determine what information every incident record must capture for later review.
1. Roles and contacts
- Incident lead and backup.
- Technical support contact.
- Legal, insurance, and law-enforcement contacts.
2. Phases
- Detect and report: how anyone raises an incident.
- Triage: severity levels and who decides.
- Contain: disable accounts, isolate devices, preserve evidence.
- Eradicate and recover: restore from known-good state.
- Review: after-action notes and improvements.
3. Notification obligations
List contractual, regulatory, insurer, and customer notification timelines that apply to you.
4. Record keeping
What each incident record must include: timeline, systems, people, actions, and outcome.
Key takeaways
- An incident response plan is only usable if it names an incident lead, a backup, and specific contacts in advance.
- The five phases — detect and report, triage, contain, eradicate and recover, review — give responders a consistent sequence to follow under pressure.
- Notification timelines vary by contract, regulator, insurer, and customer, so they must be identified and listed before an incident, not during one.
- Every incident record should capture a timeline, affected systems, people involved, actions taken, and the outcome for later review.
- The after-action review step turns each incident into an improvement to the plan rather than a one-time fire drill.
