Implementation Guidance

DoD has defined the authoritative time source as an authoritative time server which is synchronized with redundant United States Naval Observatory (USNO) time servers as designated for the appropriate DoD network (NIPRNet / SIPRNet) and/or the Global Positioning System (GPS).

Validation Procedures

The organization being inspected/assessed is automatically compliant with this CCI because they are covered at the DoD level. DoD has defined the authoritative time source as an authoritative time server which is synchronized with redundant United States Naval Observatory (USNO) time servers as designated for the appropriate DoD network (NIPRNet / SIPRNet) and/or the Global Positioning System (GPS).

Control	Description
AU-8 (1)	The information system: AU-8 (1)(a): Compares the internal information system clocks [Assignment: organization-defined frequency] with [Assignment: organization-defined authoritative time source]; and AU-8 (1)(b): Synchronizes the internal system clocks to the authoritative time source when the time difference is greater than [Assignment: organization-defined time period].
