Check Content

If using an Advanced Intrusion Detection Environment (AIDE), verify the configuration contains the "xattrs" option for all monitored files and directories.

Procedure:
Check for the default location /etc/aide/aide.conf
or:
# find / -name aide.conf

# egrep "[+]?xattrs" <aide.conf file>
If the option is not present. This is a finding.
If using a different file integrity tool, check the configuration per tool documentation.
