CCI-002762

Defines the mean time to failure (MTTF) substitution criteria to be employed as a means to determine the need to exchange active and standby components.

Implementation Guidance

The organization being inspected/assessed defines and documents the mean time to failure substitution criteria to be employed as a means to determine the need to exchange active and standby components. DoD has determined the mean time to failure is not appropriate to define at the Enterprise level.

Validation Procedures

The organization conducting the inspection/assessment obtains and examines the documented mean time to failure to ensure the organization being inspected/assessed defines the mean time to failure substitution criteria to be employed as a means to determine the need to exchange active and standby components. DoD has determined the mean time to failure is not appropriate to define at the Enterprise level.

Compelling Evidence

1.) Signed and dated System security plan defines the mean time to failure substitution criteria to be employed as a means to determine the need to exchange active and standby components.
