Verify that SLEM 5 file integrity tool is configured to verify extended attributes.

> sudo 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 selection lines in the "/etc/aide.conf" file, or extended attributes are not being checked by another file integrity tool, this is a finding.

Fix Text (F-65042r996081_fix)

Configure SLEM 5 file integrity tool to check file and directory extended attributes.

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