Ask the SA if the file integrity tool is configured to monitor directories and files for xattrs settings. If using the Advanced Intrusion Detection Environment (AIDE) tool, verify the configuration file (aide.conf) contains the xattrs option for all monitored files and directories. See the following example. # find / -type f -name aide.conf \| xargs -n1 ls -lL # cat /aide.conf \| tr '\011' ' ' \| tr -s ' ' \| sed -e 's/^[ \t]*//' \|grep -v "^#" \| \ egrep -i "^xattrs = \|xattrs" If the option is not present, this is a finding. If using a different file integrity tool, check the configuration per the tool vendor's documentation.
