Assessment Title

Rule Text

Ubuntu 22.04 LTS must record time stamps for audit records that can be mapped to Coordinated Universal Time (UTC).

Description

Discussion Text

If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analysis. Time stamps generated by the operating system include date and time. Time is commonly expressed in UTC or local time with an offset from UTC.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Assessment Script Powered by AISandbox-executed

A standalone Shell script to assess this control automatically. Review before running it in your environment.

Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.

#!/bin/sh
# OVAL Definition: oval:mil.disa.stig.ubuntu2204os:def:260521
if [ -e /etc/localtime ] && [ "$(readlink -f /etc/localtime)" = "/usr/share/zoneinfo/Etc/UTC" ]; then echo "PASS"; else echo "FAIL"; fi
exit 1

Remediation

To Configure Ubuntu 22.04 LTS time zone to use UTC, run the following command: 
  
     $ sudo timedatectl set-timezone Etc/UTC
