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 content

Verify that 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 timezone Timezone: UTC (UTC, +0000) If "Timezone" is not set to UTC or GMT, this is a finding.

Fix text

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]

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
