Rules and policies are made up of objects (addresses, services, interfaces, and so on).
The following list describes the main types of objects:
Address objects define network nodes, groups of nodes, or networks.
Service objects (and service group objects) define port numbers used by particular services and are used in security policies.
Interface objects denote interfaces on the firewall.
Certificate objects are the certificates used for encryption and authentication between SunScreen firewalls and remote administration stations.
