Determine the ownership of the executed programs. # cat /etc/rc* /etc/init.d/* | more Check the ownership of every program executed by the system start-up files. # ls -l <executed program> If any executed program is not owned by root, sys, bin, or in rare cases, an application account, this is a finding.

Change the ownership of the file executed from system startup scripts to root, bin, or sys. # chown root <executed file>
