What an Incident Response Plan Needs

Your SOC 2 incident response plan (IRP) maps to CC7.3-CC7.5 in Trust Services Criteria. Auditors check that you have a documented process for handling security incidents — and that your team follows it.

The Five Sections

SectionWhat to Include
1. DetectionHow incidents are identified (monitoring tools, customer reports, automated alerts)
2. ClassificationSeverity levels and criteria (P1 = data breach, P2 = service outage, P3 = minor issue)
3. ResponseWho gets notified, what actions they take, escalation path
4. CommunicationHow you notify affected customers, internal stakeholders, and regulators if required
5. Post-incident reviewRoot cause analysis process, timeline for review, lessons learned documentation

A Startup-Sized Example

Detection

"Security events are detected through Sentry error monitoring, AWS CloudWatch alarms, and PagerDuty alerting. Customers can report issues to security@company.com."

Classification

  • P1 (Critical): Confirmed data breach, unauthorized access to customer data
  • P2 (High): Service outage affecting customers, credential compromise
  • P3 (Medium): Failed authentication attempts, minor configuration issues

Response

"P1: CTO notified within 15 minutes via PagerDuty. Affected systems isolated. Investigation begins immediately. P2: On-call engineer responds within 1 hour. P3: Tracked in Linear, addressed within 5 business days."

Communication

"Affected customers notified within 72 hours for P1 incidents. Status page updated for P2+ incidents."

Post-Incident Review

"Post-mortem document created within 5 business days. Team reviews root cause, timeline, and preventive measures. Document stored in Notion."

Tips

  • Keep it realistic. If your team is five people, don't describe a Security Operations Center rotation.
  • Name your tools. PagerDuty, Sentry, Slack #incidents — auditors want specifics.
  • Test it. Run a tabletop exercise once before your audit so you can tell the auditor you've tested the plan.
