The purpose of change management in information security is fundamentally about understanding, communicating, and documenting changes to systems and processes. This encompasses the entire lifecycle of changes, from planning and approval through to implementation and review. By maintaining clear records and communication regarding changes, organizations can ensure that all stakeholders are aware of alterations that may impact security postures, compliance requirements, or operational functionality.

Effective change management supports a structured approach, reducing risks associated with changes. It helps in evaluating the potential impact of changes on the security environment before they are applied and ensures that appropriate assessments (like risk assessments) are performed to mitigate possible adverse effects. This makes it easier to track what changes were made, why, and by whom, which is essential for compliance with various regulations and for conducting audits.

In contrast, monitoring user access logs, preventing unauthorized changes to data, and implementing firewall rules are all important aspects of overall security strategy, but they represent more specific functions or controls rather than the holistic process that change management encompasses. These functions can all be informed by effective change management to ensure that any alterations in the system do not create new vulnerabilities or risk profiles.
