CCI-001323

Manually initiate transfers between active and standby system components when the use of the active component reaches an organization-defined percentage of the mean time to failure.

Implementation Guidance

Determine if transfers are initiated manually between active and standby system components when the use of the active component reaches [SI-13(03)_ODP; the percentage of the mean time to failure for transfers to be manually initiated is defined] of the mean time to failure.

Validation Procedures

Examine: [SELECT FROM: System and information integrity policy; system and information integrity procedures; procedures addressing predictable failure prevention; system design documentation; system configuration settings and associated documentation; system audit records; system security plan; other relevant documents or records]. Interview: [SELECT FROM: Organizational personnel responsible for MTTF activities; organizational personnel with information security responsibilities; system/network administrators; organizational personnel with contingency planning responsibilities]. Test: [SELECT FROM: Organizational processes for managing MTTF and conducting the manual transfer between active and standby components].
