• ID: /frameworks/fedramp-moderate-security-controls/sc/45/01

Description

(a) Compare the internal system clocks [FedRAMP Assignment: At least hourly] with [FedRAMP Assignment: http://tf.nist.gov/tf-cgi/servers.cgi]; and

(b) Synchronize the internal system clocks to the authoritative time source when the time difference is greater than [FedRAMP Assignment: any difference].

SC-45(1) Additional FedRAMP Requirements and Guidance:

Guidance: Synchronization of system clocks improves the accuracy of log analysis.

Requirement: The service provider selects primary and secondary time servers used by the NIST Internet time service. The secondary server is selected from a different geographic region than the primary server.

Requirement: The service provider synchronizes the system clocks of network computers that run operating systems other than Windows to the Windows Server Domain Controller emulator or to the same time source for that server.
