 +====== Baseline Reuse ======
  
 +[[public:99_annexes:annex-b-terms-and-definitions:start|Go to Terms and Definitions]]
 +
 +===== Discussion =====
 +
 +Baseline Reuse applies the same identified [[public:99_annexes:annex-b-terms-and-definitions:b:baseline|Baseline]] Revision to two or more subjects, activities, or contexts without modifying the Baseline content.
 +
 +Baseline Reuse may apply the same Baseline Revision to:
 +
 +  * Multiple [[public:99_annexes:annex-b-terms-and-definitions:i:infrastructure_environment|Infrastructure Environments]]
 +  * Multiple [[public:99_annexes:annex-b-terms-and-definitions:m:machine_image|Machine Images]]
 +  * Multiple deployments
 +  * Multiple provider implementations
 +  * Multiple organizational domains
 +  * Repeated lifecycle activities
 +  * Repeated compliance assessments
 +
 +The subject-specific result may differ because of:
 +
 +  * Platform Specific Parameters
 +  * Environment-specific values
 +  * Permitted overrides
 +  * Selected optional controls
 +  * Context-specific constraints
 +
 +Those differences remain separate from the reused Baseline content.
 +
 +Baseline Reuse differs from copying and modifying a Baseline:
 +
 +  * Baseline Reuse applies the same Baseline Revision without changing its content
 +  * Copying and modifying Baseline content creates a different candidate Baseline or Revision
 +
 +Baseline Reuse also differs from Baseline Composition:
 +
 +  * Baseline Reuse applies the same Baseline Revision more than once
 +  * Baseline Composition combines content from multiple Baselines

 +
 +===== Note =====
 +
 +Baseline Reuse does not require identical resulting subjects.
 +
 +The applicable requirements determine which subject-specific values may vary without changing the reused Baseline.
 +
 +A revised Baseline is a different Revision and should remain distinguishable from the Baseline Revision previously reused.
 +
 +===== Example =====
 +
 +A build workflow applies the same Security Baseline Revision to development, test, and production Machine Images while keeping environment-specific network and monitoring values separate from the Baseline content.
