- AU-12(1): System-Wide / Time-Correlated Audit Trail
Control Statement
Compile audit records from [Assignment: organization-defined system components] into a system-wide (logical or physical) audit trail that is time-correlated to within [Assignment: organization-defined level of tolerance].
Supplemental Guidance
Audit trails are time-correlated if the time stamps in the individual audit records can be reliably related to the time stamps in other audit records to achieve a time ordering of the records within organizational tolerances.
OT Discussion
Example compensating controls include providing time-correlated audit records on a separate system.
