Security & resilience
Incident Response Starter Playbook
Prepare a coordinated response to a suspected security incident. Establish response roles, assess business impact, preserve evidence and make containment, communication and recovery decisions through a named authority, with reusable contact and incident records.
Give the first response a clear owner
An incident quickly creates competing demands for investigation, service restoration and communication. This playbook explains how to coordinate that work, distinguish observations from assumptions and keep consequential decisions traceable. Use it to prepare the response team and maintain a controlled record while the incident develops.
Inside the resource
Prepare roles and assess the report
Define the incident lead, technical response, business authority and communication route. Capture the initial report, assess impact and establish a controlled coordination channel.
Contain the incident and recover service
Choose containment with the service owner, preserve useful evidence and record uncertainty. Coordinate approved messages, verify recovery and establish the conditions for normal operation.
Maintain the response records
Complete the escalation directory and incident coordination record. Keep contacts, authority, decisions and next actions accessible, then use the review to improve the response process.
A few practical details
Is this a technical investigation runbook?
It is a coordination playbook. The technical owner should supply system-specific investigation, containment and recovery procedures, including the access and safeguards required to execute them.
What belongs in the incident record?
Record observed facts, affected service, impact, decisions, authority, action owners and the next review. Keep sensitive evidence in its approved location and link through controlled identifiers.
How should we test the playbook?
Rehearse a disruption with the people named in the directory. Check unavailable contacts, loss of the usual communication channel, decision authority and restoration of the business task.
