Authoritative Time Source

Assures a traceable, standard time source for use within an infrastructure (e.g., server clocks are synced to the time source to enable events occuring on one server to be correlated with those occurring on another during incident response)

Control Specification +-

An external accurate, externally agreed upon, time source shall be used to synchronize the system clocks of all relevant information processing systems within the organization or explicitly defined security domain to facilitate tracing and reconstitution of activity timelines. Note: specific legal jurisdictions and orbital storage and relay platforms (US GPS & EU Galileo Satellite Network) may mandate a reference clock that differs in synchronization with the organizations domicile time reference, in this event the jurisdiction or platform is treated as an explicitly defined security domain.

Do you utilize a synchronized time-service protocol (ex. NTP) to ensure all systems have a common time reference?
