====== Baseline Selection ======

[[dido:99_annexes:annex-b-terms-and-definitions:start|Go to Terms and Definitions]]

===== Discussion =====

Baseline Selection chooses an identified [[dido:99_annexes:annex-b-terms-and-definitions:b:baseline|Baseline]] Revision for application to a specified subject, activity, or context.

The selection may depend on:

  * The subject being governed
  * The target [[dido:99_annexes:annex-b-terms-and-definitions:i:infrastructure_environment|Infrastructure Environment]]
  * The deployment purpose
  * The implementation platform
  * Security classification
  * Applicable policy
  * Applicable jurisdiction
  * Delivery phase
  * Operational state
  * Effective date
  * Approval status
  * Compatibility constraints

Baseline Selection may choose:

  * An Infrastructure Baseline
  * A Security Baseline
  * A Deployment Baseline
  * A Machine Image Baseline
  * A Compliance Baseline
  * A composition of multiple Baselines

Baseline Selection differs from [[dido:99_annexes:annex-b-terms-and-definitions:b:baseline_approval|Baseline Approval]]:

  * Baseline Approval authorizes a Baseline Revision for a defined use
  * Baseline Selection chooses the approved or otherwise applicable Baseline Revision for a particular context

Baseline Selection also differs from Baseline Composition:

  * Baseline Selection chooses one or more applicable Baselines
  * Baseline Composition combines selected Baseline content according to defined composition rules

===== Note =====

Baseline Selection should identify:

  * The selected Baseline
  * The selected Revision
  * The subject or activity to which it applies
  * The selection criteria
  * The effective context
  * The selecting actor or process

Selection of a Baseline does not by itself establish that the Baseline is approved or that the subject conforms to it.

Applicable requirements determine whether only approved Baselines may be selected.

===== Example =====

A deployment workflow selects the approved production Security Baseline Revision applicable to the target operating system and security classification.
