Which of the following best describes a checklist of actions taken during an incident?

A playbook is a predefined set of procedures or actions that are to be followed during an incident response. It serves as a practical guide that outlines the steps to take in various scenarios, ensuring that responses are systematic, organized, and efficient. Playbooks typically include specific actions for containment, eradication, and recovery, along with other relevant information to aid responders in managing incidents effectively.

This structured approach helps maintain consistency across responses to incidents, allowing teams to act swiftly and confidently. In the context of incident response, having a checklist ensures that critical actions aren't overlooked and that all aspects of the response process are addressed.
