# ZClass>Define Permissions

This view allows you to map permissions on an object to define security settings when it is used as a method.

In general you should map the `View` permission to the `View` permission. For some kinds of objects you may wish to enable additional permission mappings. For example, ZClasses should map their `Create class instances` permission to the permission used by the ZClass factory.

To manage the permissions mapping, select the target permission from the select list for each permission that you wish to map and then click the `Change` button.
