Vulnerability discussion

Cron logging can be used to trace the successful or unsuccessful execution of cron jobs. It can also be used to spot intrusions into the use of the cron facility by unauthorized and malicious users.

Check content

Verify that "rsyslog" is configured to log cron events. Check the configuration of "/etc/rsyslog.conf" or "/etc/rsyslog.d/*.conf" files for the cron facility with the following command: Note: If another logging package is used, substitute the utility configuration file for "/etc/rsyslog.conf" or "/etc/rsyslog.d/*.conf" files. # grep cron /etc/rsyslog.conf /etc/rsyslog.d/*.conf cron.* /var/log/cron.log If the command does not return a response, check for cron logging all facilities by inspecting the "/etc/rsyslog.conf" or "/etc/rsyslog.d/*.conf" files. Look for the following entry: *.* /var/log/messages If "rsyslog" is not logging messages for the cron facility or all facilities, this is a finding.

Fix text

Configure "rsyslog" to log all cron messages by adding or updating the following line to "/etc/rsyslog.conf" or a configuration file in the /etc/rsyslog.d/ directory: cron.* /var/log/cron.log

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.
