Assessment Procedure

Check Text

# more /etc/rsyslog.conf
Examine /etc/rsyslog.conf and determine the log file(s) receiving logs for "mail.crit", "mail.debug", mail.*, or "*.crit".
Check the permissions on these log files.
# ls -lL <log file>

If the permissions include a '+', the file has an extended ACL. If the file has an extended ACL and it has not been documented with the IAO, this is a finding.

Implementation Procedure

Fix Text

This fix is applicable to both Postfix and sendmail servers.
Remove the extended ACL from the file.
# setfacl --remove-all <log file>
