CCI-001325

The organization defines a time period that the mean time to failure (MTTF) must exceed before the organization manually initiates a transfer between active and standby information system components.

Implementation Guidance

The organization being inspected/assessed defines and documents a time period that the mean time to failure must exceed before the organization manually initiates a transfer between active and standby information system components. The time period should be based on organizational need to maintain readiness of standby components. DoD has determined the time period is not appropriate to define at the Enterprise level.

Validation Procedures

The organization conducting the inspection/assessment obtains and examines the documented time period to ensure the organization being inspected/assessed defines a time period that the mean time to failure must exceed before the organization manually initiates a transfer between active and standby information system components. DoD has determined the time period is not appropriate to define at the Enterprise level.

Compelling Evidence

1.) Signed and dated System security plan defines a time period that the mean time to failure must exceed before the organization manually initiates a transfer between active and standby information system components. The time period should be based on organizational need to maintain readiness of standby components.
