Vulnerability discussion

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

Check content

Check the /etc/syslog-ng/syslog-ng.conf for the following log entries: filter f_mailinfo { level(info) and facility(mail); }; filter f_mailwarn { level(warn) and facility(mail); }; filter f_mailerr { level(err, crit) and facility(mail); }; filter f_mail { facility(mail); }; If present, this is not a finding.

Fix text

Edit the /etc/syslog-ng/syslog-ng.conf file and add the following log entries: filter f_mailinfo { level(info) and facility(mail); }; filter f_mailwarn { level(warn) and facility(mail); }; filter f_mailerr { level(err, crit) and facility(mail); }; filter f_mail { facility(mail); }; destination mailinfo { file("/var/log/mail.info"); }; log { source(src); filter(f_mailinfo); destination(mailinfo); }; destination mailwarn { file("/var/log/mail.warn"); }; log { source(src); filter(f_mailwarn); destination(mailwarn); }; destination mailerr { file("/var/log/mail.err" fsync(yes)); }; log { source(src); filter(f_mailerr); destination(mailerr); };

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.
