SV-88721r1_rule The Cisco ISR 4000 Series router must record time stamps for audit records that can be mapped to Coordinated Universal Time (UTC) or Greenwich Mean Time (GMT).

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 application 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.

Check content

Verify that the Cisco ISR 4000 Series router time stamps for audit logs can be mapped to UTC or GMT by using the show logging command. The configuration should look similar to the following example: clock timezone MST -7 0 service timestamps datetime localtime If the time stamps cannot be map to UTC or GMT, this is a finding.

Fix text

Configure the timezone for the local time, then map the time stamps back to UCT or GMT. The configuration should look similar to the example below: clock timezone MST -7 0 service timestamps datetime localtime

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.
