Check Text ( C-42979r1_chk )
By default, rsyslog includes configuration files found in the /etc/rsyslog.d directory. Check for the include directive” $IncludeConfig /etc/rsyslog.d/.conf” in /etc/rsyslog.conf and then for the cron log configuration file. # grep rsyslog.d /etc/rsyslog.conf # grep cron /etc/rsyslog.d/.conf OR # grep cron /etc/rsyslog.conf If cron logging is not configured, this is a finding. Check the configured cron log file found in the cron entry of /etc/syslog (normally /var/log/cron). # ls -lL /var/log/cron If this file does not exist, or is older than the last cron job, this is a finding.

By default, rsyslog includes configuration files found in the /etc/rsyslog.d directory. Check for the include directive” $IncludeConfig /etc/rsyslog.d/*.conf” in /etc/rsyslog.conf and then for the cron log configuration file.
# grep rsyslog.d /etc/rsyslog.conf
# grep cron /etc/rsyslog.d/*.conf

OR

# grep cron /etc/rsyslog.conf
If cron logging is not configured, this is a finding.

Check the configured cron log file found in the cron entry of /etc/syslog (normally /var/log/cron).
# ls -lL /var/log/cron

If this file does not exist, or is older than the last cron job, this is a finding.
