Fix Recommendation

Configure the file integrity tool to check file and directory extended attributes.

If AIDE is installed, ensure the "xattrs" rule is present on all uncommented file and directory selection lists.

Check Contents

Verify AIDE is configured to verify extended attributes using the following command:

$ grep xattrs /etc/aide.conf

All= p+i+n+u+g+s+m+S+sha512+acl+xattrs+selinux

If the "xattrs" rule is not being used on all uncommented selection lines in the "/etc/aide.conf" file, or extended attributes are not being checked by another file integrity tool, this is a finding.
