Title

SLEM 5 file integrity tool must be configured to verify extended attributes. (Cat II impact)

Discussion

Extended attributes in file systems are used to contain arbitrary data and file metadata with security implications.

Check Content

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

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.
