SV-88723r1_rule The Cisco ISR 4000 Series router must record time stamps for audit records that meet a granularity of one second for a minimum degree of precision.

Vulnerability discussion

Without sufficient granularity of time stamps, it is not possible to adequately determine the chronological order of records. Time stamps generated by the application include date and time. Granularity of time measurements refers to the degree of synchronization between information system clocks and reference clocks.

Check content

Verify that the time stamps for audit records have a granularity of one second. The configuration should look similar to the example below: service timestamps debug datetime msec service timestamps log datetime year If the time stamps have a granularity larger than one second, this is a finding.

Fix text

Configure the Cisco ISR 4000 Series router to have a granularity of one second for audit log time stamps. The configuration should look like the example below: service timestamps debug datetime msec service timestamps log datetime year

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.
