SC-45(1) Synchronization with Authoritative Time Source
Control enhancement of SC-45 System Time Synchronization
Control
Compare the internal system clocks [Assignment: frequency] with [Assignment: authoritative time source] ; and
Synchronize the internal system clocks to the authoritative time source when the time difference is greater than [Assignment: time period].
Discussion
Synchronization of internal system clocks with an authoritative source provides uniformity of time stamps for systems with multiple system clocks and systems connected over a network.
Need SC-45(1) implemented and evidenced?
We assess where you stand against this control, document the gap, and build the remediation plan your auditor and your board will both accept.
