Because ZENworks has a strong implementation of the access control layer through its roles and rights, by properly configuring these for the users, you can ensure that they have access only to relevant information.
Restrict the access to ZCC servers only to authorized persons. You can restrict ZCC access from a network subnet or IP range, so that unauthorized access to ZCC is prevented. For more information, see Securing DMZ Servers
in the ZENworks Control Center Reference.
