Abstract
A network system includes a network edge point configured to provide a terminal with access to a network. The network edge point includes a security policy associated with the terminal, and controls communications between the network and the terminal according to the security policy. The security policy may include a personal filter downloaded from the terminal, a service filter downloaded from a service policy server, and/or a domain filter downloaded from a domain policy server. The terminal may access the network through a second network edge point. The second network edge point may download one or more of the filters from the first network edge point, and control communications between the network and the terminal according to the security policy.
