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

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.
