Baselining is the process of establishing a reference point for the standard configuration of systems, networks, or applications. This baseline represents the approved, secure state. By continuously comparing the current environment to the baseline, organizations can detect deviations, unauthorized changes, or misconfigurations.

Patch management involves updating systems, deployment refers to installing new systems, and capacity management focuses on resource planning. While important, these do not establish a standard state for comparison.

Baselining is essential for change management and security auditing. It supports configuration management databases (CMDBs), intrusion detection, and compliance requirements. When deviations are detected, they can be escalated for remediation or formally approved through change control processes.
