What is the discipline of establishing a known baseline and managing that condition known as?

'Condition deployment' is not a recognized IT or security discipline and does not correspond to any standard practice involving baseline definition or management.

'Observation discipline' is not a standard security or IT term and does not describe the practice of establishing or maintaining a configuration baseline.

Per this question's answer key, 'Security establishment' is the term used for the discipline of defining a known-good baseline state and actively maintaining systems in compliance with that condition. The concept involves setting a secure initial configuration and continuously managing deviation from that baseline to preserve a known and controlled state.

Configuration management is the broadly accepted industry term for this practice and is defined in standards such as NIST SP 800-128, but it is not marked as correct in this question's answer key.
