Vulnerability Discussion

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 SUSE operating system include date and time. Time is commonly expressed in UTC, a modern continuation of GMT, or local time with an offset from UTC.

Check

Verify the SUSE operating system is configured to use UTC or GMT.

Check that the SUSE operating system is configured to use UTC or GMT with the following command:

> timedatectl status | grep -i "time zone"
Time zone: UTC (UTC, +0000)

If "Time zone" is not set to "UTC" or "GMT", this is a finding.

Fix

Configure the SUSE operating system is configured to use UTC or GMT.

To configure the system time zone to use UTC or GMT, run the following command, replacing [ZONE] with "UTC" or "GMT".

> sudo timedatectl set-timezone [ZONE]
