Network administration in Trusted Extensions is based on security templates. A security template describes a set of hosts that have identical protocols and security attributes.
Security attributes are administratively assigned to remote systems, both hosts and routers, by means of templates. The security administrator administers templates and assigns them to remote systems. If a remote system is not assigned a template, no communications are allowed with that system.
Every template is named and includes the following:
One of four host types: unlabeled, cipso, adaptive, or netif. The protocol that is used for network communications is determined by the host type of the template. See Host Type and Template Name in Security Templates.
A set of security attributes that are applied to each host type.
