Which of the following should a security operations center use to improve its incident response procedure?

Playbooks are detailed, step-by-step guides that outline specific actions to be taken during various incident types. They ensure consistent, efficient, and effective responses by providing clear instructions, roles, and communication protocols, thereby improving incident response procedures. Frameworks (like NIST or ISO 27001) provide a high-level structure for security programs but don't offer the granular, actionable steps needed for incident response. Baselines define normal system behavior and are used for detection, not for response procedures. Benchmarks are used for comparing performance against industry standards, not for guiding incident response actions.
