Change management is the formal process designed to control, document, approve, and track modifications to systems, internal processes, assets, and security controls. This control mechanism helps prevent unauthorized or unintended changes that could introduce vulnerabilities or disrupt operations.
Playbooks are documented procedures for responding to incidents, incident response manages security incidents, and acceptable use policies define acceptable user behavior but do not directly control changes.
By enforcing proper change management, organizations maintain the integrity and security of their infrastructure, which is a critical topic covered in the Security Program Management and Oversight domain of SY0-701#6:Chapter 16 CompTIA Security+ Study Guide#
