Discussion

ACLs can provide permissions beyond those permitted through the file mode and must be verified by file integrity tools.

Check Content

If using an Advanced Intrusion Detection Environment (AIDE), verify that the configuration contains the "ACL" option for all monitored files and directories.

Procedure:
Check for the default location /etc/aide/aide.conf
or:
# find / -name aide.conf

# egrep "[+]?acl" <aide.conf file>
If the option is not present. This is a finding.

If using a different file integrity tool, check the configuration per tool documentation.

Fix Text

If using AIDE, edit the configuration and add the "ACL" option for all monitored files and directories.

If using a different file integrity tool, configure ACL checking per the tool's documentation.
