Which of the following is most likely to be used as a just-in-time reference document within a security operations center?

A playbook is a detailed, step-by-step guide for responding to specific security incidents or alerts. It provides security analysts with immediate, actionable instructions, making it an essential just-in-time reference for consistent and efficient incident response within a Security Operations Center (SOC). Change management policy outlines procedures for modifying systems but isn't a direct incident response guide. A risk profile assesses an organization's overall risk posture, not specific incident handling. A SIEM profile defines how a Security Information and Event Management system collects and analyzes data, rather than guiding human response actions.
