1. An apparatus for secure communication between at least one user client station via at least one port device and a network, said apparatus comprising:
- at least one firewall, each of said at least one firewall being connected to one of said at least one port device;
an authentication/encryption unit having a configuration data path connected to each of said at least one firewall, a switching unit for transmitting data connected to each of said at least one firewall and to said authentication/encryption unit;
wherein a new user client station has permission at said at least one firewall to access only an authentication function of said authentication/encryption unit until said authentication/encryption unit communicates a permission profile for said new user over said configuration data path.

28. A method for secure communication between at least one user client station via at least one port device and a network, each of said at least one port device being connected to a firewall, said firewall being connected to a switching unit and to an authentication/encryption unit using a configuration path, said method comprising the steps of:
-
establishing an authentication link between at least one of said at least one user client station and said authentication/encryption unit;
authenticating said at least one of said at least one user client stations and retrieving a profile;
applying said profile configuration to said at least one of said firewall using said configuration path; and
allowing said at least one user client station to communicate according to said profile configuration, if said authentication is successful. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
