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.

Verify RHEL 10 rsyslog is configured to log cron events 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.

$ sudo grep -s cron /etc/rsyslog.conf /etc/rsyslog.d/*.conf
/etc/rsyslog.conf:*.info;mail.none;authpriv.none;cron.none /var/log/messages
/etc/rsyslog.conf:cron.* /var/log/cron

If the command does not return a response, check for cron logging all facilities with the following command:

$ logger -p local0.info "Test message for all facilities."

Check the logs for the test message with the following:

$ sudo tail /var/log/messages

If "rsyslog" is not logging messages for the cron facility or all facilities, this is a finding.
