Vulnerability discussion

If informational and more severe SMTP service messages are not logged, malicious activity on the system may go unnoticed.

Check content

The syslog.conf file critical mail logging option line will typically appear as one of the following examples: mail.crit /var/adm/messages mail.* /var/adm/messages *.* /var/adm/messages *.crit /var/adm/messages Check the syslog configuration file for mail.crit logging configuration. # cat /etc/syslog.conf | tr '\011' ' ' | tr -s ' ' | sed -e 's/^[ \t]*//' | grep -v "^#" | egrep -i "mail.crit|mail.\*|\*.crit|\*.\*" If syslog is not configured to log critical sendmail messages, this is a finding.

Fix text

Edit the syslog.conf file and add a configuration line specifying an appropriate destination for critical "mail" syslogs, for example: mail.crit /var/adm/messages mail.* /var/adm/messages *.* /var/adm/messages *.crit /var/adm/messages

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.
