Check Text ( C-36950r1_chk )
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"
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 (F-32214r1_fix)
If using AIDE, edit the configuration and add the "ACL" option for all monitored files and directories.
