Incident response playbook
Demonstrate that the organization maintains documented, tested, and accessible incident response playbooks that prescribe specific procedures for identified threat scenarios and enable coordinated, effective incident handling.
Description
What this control does
An incident response playbook is a documented, structured set of procedures that define step-by-step actions for detecting, analyzing, containing, eradicating, and recovering from specific types of security incidents. Playbooks operationalize the organization's incident response plan by providing actionable guidance tailored to incident categories such as ransomware, data exfiltration, account compromise, or DDoS attacks. Each playbook typically includes trigger conditions, role assignments, technical response actions, communication protocols, evidence collection requirements, and decision trees to ensure consistent, effective response under time pressure.
Control objective
What auditing this proves
Demonstrate that the organization maintains documented, tested, and accessible incident response playbooks that prescribe specific procedures for identified threat scenarios and enable coordinated, effective incident handling.
Associated risks
Risks this control addresses
- Delayed or inconsistent incident response due to lack of pre-defined procedures during active security events
- Inadequate evidence preservation resulting from responders unaware of forensic collection requirements during containment actions
- Uncoordinated response efforts where multiple teams take conflicting or redundant actions without clear role assignments
- Failure to escalate critical incidents to executive leadership or external entities such as law enforcement or regulators within required timeframes
- Incomplete eradication of threats because playbooks do not address all attack vectors or persistence mechanisms for specific threat types
- Ineffective stakeholder communication that damages trust or violates contractual notification obligations
- Missed containment opportunities due to responders unfamiliar with technical procedures for isolating compromised systems or accounts

Testing procedure
How an auditor verifies this control
- Request and review the complete inventory of documented incident response playbooks, noting coverage of incident types including malware, ransomware, data breach, insider threat, DDoS, and account compromise.
- Select three high-risk playbooks based on organizational threat profile and verify each includes defined trigger criteria, assigned roles and responsibilities, technical response procedures, escalation paths, and evidence collection requirements.
- Interview incident response team members to confirm they can locate and access playbooks during an incident and understand their assigned responsibilities within each playbook.
- Review playbook version control records to verify playbooks are maintained under change management with approval workflows and revision history.
- Examine tabletop exercise or simulation records from the past 12 months to confirm playbooks were tested against realistic scenarios and identify whether lessons learned resulted in playbook updates.
- Trace at least two actual incidents from the past year to their corresponding playbooks and verify responders followed documented procedures, documenting any deviations and whether playbooks were updated post-incident.
- Verify playbooks reference technical runbooks, contact lists, communication templates, and external dependencies such as cyber insurance contacts or forensic vendor engagement procedures.
- Confirm playbooks align with regulatory notification timelines applicable to the organization and include decision criteria for determining reportable incidents.
