What is a playbook in incident response?

An incident response playbook is a predefined, step-by-step procedure for handling a specific type of security incident, such as ransomware, phishing compromise, data breach, or distributed denial of service attack. Each playbook outlines detection criteria, containment actions, eradication steps, recovery procedures, communication requirements, and escalation paths specific to that incident type. Playbooks reduce response time by eliminating decision paralysis during high-stress incidents and ensure consistent, thorough responses regardless of which team member is on call. ---
