AU-8: Time Stamps


2019-05-20 15:48:11.984914




The information system:

Code Description
AU-8a. Uses internal system clocks to generate time stamps for audit records; and
AU-8b. Records time stamps for audit records that can be mapped to Coordinated Universal Time (UTC) or Greenwich Mean Time (GMT) and meets [Assignment: organization-defined granularity of time measurement].


STIG # Description Result
V-72887 PostgreSQL must record time stamps, in audit records and application data, that can be mapped to Coordinated Universal Time (UTC, formerly GMT). passed
V-72985 PostgreSQL must generate time stamps, for audit records and application data, with a minimum granularity of one second. passed

Additional Guidance

Time stamps generated by the information system include date and time. Time is commonly expressed in Coordinated Universal Time (UTC), a modern continuation of Greenwich Mean Time (GMT), or local time with an offset from UTC. Granularity of time measurements refers to the degree of synchronization between information system clocks and reference clocks, for example, clocks synchronizing within hundreds of milliseconds or within tens of milliseconds. Organizations may define different time granularities for different system components. Time service can also be critical to other security capabilities such as access control and identification and authentication, depending on the nature of the mechanisms used to support those capabilities.
