An XCCDF Rule
Description
Approved time servers must be the only servers configured for use. This rule ensures the uniformity of time stamps for information systems with multiple system clocks and systems connected over a network. An authoritative time server is synchronized with redundant United States Naval Observatory (USNO) time servers as designated for the appropriate DOD network.
