Title

All network services daemon files must have mode 0755 or less permissive. (Cat II impact)

Discussion

Restricting permission on daemons will protect them from unauthorized modification and possible system compromise.

Check Content

Check the mode of network services daemons. # ls -la /usr/bin /usr/sbin If the mode of a network services daemon is more permissive than 0755, this is a finding. NOTE: Network daemons not residing in these directories (such as httpd or sshd) must also be checked for the correct permissions. A way to locate network daemons, such as httpd and sshd, is with the ps command. # ps -ef | egrep '(sshd|httpd)'

Fix Text

Change the mode of the network services daemon. # chmod 0755 <path>
