Check Text ( C-35029r1_chk )
Ask the SA if the file integrity tool is configured to monitor directories and files for ACL settings. If using the Advanced Intrusion Detection Environment (AIDE) tool, verify the configuration file (aide.conf) contains the ACL option for all monitored files and directories. See the following example. # find / -type f -name aide.conf \| xargs -n1 ls -lL # cat /aide.conf \| tr '\011' ' ' \| tr -s ' ' \| sed -e 's/^[ \t]*//' \|grep -v "^#" \| \ egrep -i "^acl = \|acl" If the option is not present, this is a finding. If using a different file integrity tool, check the configuration per tool the vendor's documentation.

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 vendor's documentation.
