AU-8Time Stamps

Use internal system clocks to generate time stamps for audit records; and Record time stamps for audit records that meet {{ insert: param, au-08_odp }} and that use Coordinated Universal Time, have a fixed local time offset from Coordinated Universal Time, or that include the local time offset as part of the time stamp.

CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.

CWE Name CVEs Why this control addresses it
CWE-362Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')2,603Accurate timestamps from internal clocks enable detection of race conditions by providing reliable event ordering in audit logs.
CWE-367Time-of-check Time-of-use (TOCTOU) Race Condition755Timestamps meeting UTC or offset standards help identify TOCTOU issues through precise chronological reconstruction of check/use operations.
CWE-778Insufficient Logging23Requiring internal clock-based timestamps directly improves audit record completeness, reducing the impact of insufficient logging for incident analysis.
