name	building-incident-response-playbook
description	Designs and documents structured incident response playbooks with step-by-step procedures per incident type, decision trees, escalation criteria, RACI matrices, and SOAR platform integration, aligned to NIST SP 800-61r3 and SANS PICERL. Use when creating or maturing an IR program, documenting response runbooks for a new incident type, or designing SOAR playbooks.

Building Incident Response Playbooks

When to Use

• Establishing or maturing an incident response program from scratch
• Documenting procedures for a new incident type after a novel attack
• Automating response workflows in a SOAR platform (Cortex XSOAR, Splunk SOAR)
• Preparing for compliance audits requiring documented IR procedures (SOC 2, PCI-DSS, HIPAA)
• Conducting a gap analysis of existing IR capabilities against specific threat scenarios

Do not use for one-time ad hoc investigations; playbooks are reusable procedure documents, not case-specific reports.

Prerequisites

• Organizational risk assessment identifying top incident scenarios by likelihood and impact
• NIST SP 800-61r3 or SANS PICERL framework adopted as the organizational IR standard
• Asset inventory with business criticality ratings and data classification
• RACI chart defining roles: Incident Commander, SOC analysts, system administrators, legal, communications
• Existing detection capabilities inventory (SIEM rules, EDR detections, IDS signatures)
• SOAR platform access if building automated playbooks

Workflow

Step 1: Select and Scope the Incident Type

Define the specific scenario the playbook will address:

• Identify the top incident types based on organizational risk assessment and historical data
• Scope each playbook to a single incident type for clarity (do not combine unrelated scenarios)
• Define trigger conditions that activate the playbook

Common playbook types:

Priority Playbooks (build first):
1. Ransomware incident response
2. Phishing/credential compromise
3. Business email compromise
4. Malware infection
5. Data breach/exfiltration
6. DDoS attack
7. Insider threat
8. Account takeover
9. Web application compromise
10. Cloud infrastructure compromise

Step 2: Define the Playbook Structure

Every playbook should follow a consistent structure:

PLAYBOOK TEMPLATE
━━━━━━━━━━━━━━━━
1. Playbook Metadata
   - Name, version, owner, last review date
   - Trigger conditions
   - Severity criteria

2. RACI Matrix
   - Who is Responsible, Accountable, Consulted, Informed for each step

3. Detection & Triage
   - How the incident is detected
   - Initial triage checklist
   - Severity classification criteria

4. Containment
   - Short-term containment actions
   - Long-term containment actions
   - Evidence preservation requirements

5. Eradication
   - Root cause identification
   - Malware/threat removal steps
   - Verification procedures

6. Recovery
   - System restoration steps
   - Validation criteria
   - Monitoring requirements post-recovery

7. Post-Incident
   - Lessons learned meeting trigger
   - Report template
   - Detection improvement actions

8. Communication
   - Internal notification matrix
   - External notification requirements (regulators, customers, law enforcement)
   - Status update cadence

9. Appendices
   - Tool-specific procedures
   - Contact lists
   - Evidence collection checklists
