CCI-000936

Control physical access to organization-defined system distribution and transmission lines within organizational facilities using organization-defined security controls.

Implementation Guidance

Determine if physical access to [PE-04_ODP[01]; system distribution and transmission lines requiring physical access controls are defined] within organizational facilities is controlled using [PE-04_ODP[02]; security controls to be implemented to control physical access to system distribution and transmission lines within the organizational facility are defined].

Validation Procedures

Examine: [SELECT FROM: Physical and environmental protection policy; procedures addressing access control for transmission mediums; system design documentation; facility communications and wiring diagrams; list of physical security safeguards applied to system distribution and transmission lines; system security plan; other relevant documents or records]. Interview: [SELECT FROM: Organizational personnel with physical access control responsibilities; organizational personnel with information security responsibilities]. Test: [SELECT FROM: Organizational processes for access control to distribution and transmission lines; mechanisms/security safeguards supporting and/or implementing access control to distribution and transmission lines].
