SV-99191r1_rule The SMTP service log files must be owned by root.

Vulnerability discussion

If the SMTP service log file is not owned by root, then unauthorized personnel may modify or delete the file to hide a system compromise.

Check content

Check the permissions on the mail log files: # ls -la /var/log/mail # ls -la /var/log/mail.info # ls -la /var/log/mail.warn # ls -la /var/log/mail.err If any mail log file is not owned by "root", this is a finding.

Fix text

Change the ownership of the sendmail log files to "root": # chown root

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.
