SV-64317r2_rule The cronlog file must have mode 0600 or less permissive.

Vulnerability discussion

Cron logs contain reports of scheduled system activities and must be protected from unauthorized access or manipulation.

Check content

Check the mode of the cron log file. Procedure: Depending on what system is used for log processing either /etc/syslog.conf or /etc/rsyslog.conf will be the logging configuration file. Check the configured cron log file found in the cron entry in /etc/syslog.conf or /etc/rsyslog.conf (normally /var/log/cron). # grep cron /etc/syslog.conf Or: # grep cron /etc/rsyslog.conf # ls -lL /var/log/cron If the mode is more permissive than 0600, this is a finding.

Fix text

Change the mode of the cron log file. # chmod 0600 /var/log/cron

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.
