Key takeaways
- An incident response plan defines who does what when a security event hits your SaaS platform.
- This workbook includes a team roster, 4-tier severity matrix, 7-phase playbook, and communications plan.
- Maps to SOC 2 CC7.3, ISO 27001 controls 5.24 to 5.28, and common NIST IR practices.
- SecureSlate helps connect IR controls to evidence and post-incident follow-up.
Overview
When an incident happens, teams without a written plan lose hours deciding who leads, who notifies customers, and what gets preserved for forensics. A practical IR plan turns chaos into a checklist.
What makes it useful
- Named roles: Incident Commander, CISO, IT Security Lead, IT Ops, Legal, Comms, and backups with contact details.
- Severity matrix: SEV-1 Critical through SEV-4 Low with response times, escalation paths, and notification rules.
- Phase playbook: Detection, Containment, Eradication, Recovery, and Post-Incident with checklists per phase.
- Lessons learned log: Capture improvements after every SEV-1 and SEV-2 event.

Severity Levels
SEV-1 (15-minute response) through SEV-4 (next business day). Each row defines examples, escalation, and who leads. Align definitions with your on-call runbooks.
IR Playbook
Seven phases from Detection through Post-Incident. Each row lists timeframe, actions, tools, owner, and a checkbox checklist. Customize actions for your SIEM, EDR, and cloud environment.
Communications Plan
Stakeholder notification matrix: executives, legal, DPO, customers, regulators, and media. Includes channel and message templates.
Lessons Learned Log
Post-incident improvements with owner, due date, and status. Link to tickets for audit sampling.

|---|---|
| Documented IR process | IR Playbook |

Common mistakes
- Plan exists but names and phone numbers are blank
- Severity definitions do not match what on-call actually does
- No legal or DPO contact for data breach scenarios
- Lessons learned logged but actions never tracked to completion
