incident-resp-playbook

name	incident-resp-playbook
description	Designs and documents structured incident response playbooks that define step-by-step procedures for specific incident types aligned with NIST SP 800-61r3 and SANS PICERL frameworks. Covers playbook structure, decision trees, escalation criteria, RACI matrices, and integration with SOAR platforms. Activates for requests involving IR playbook creation, incident response procedure documentation, response runbook development, or SOAR playbook design.

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
