Abstract: A device for protecting secured areas in a computer system which includes at least one storage unit divided into at least two storage areas. The device includes input-output (I/O) interfaces for connecting between the computer system and the storage unit, a managing controller connected to the I/O interfaces and communication interfaces connected to the managing controller, for linking between the computer system and communication networks. The managing controller provides the computer system with a selection between at least two modes. In each mode, the managing controller provides access to and from the computer to selected storage areas and communication networks. Furthermore, in each mode, the managing controller denies or provides limited access to and from the computer to non-selected storage areas and communication networks.

Abstract: Method for selectively connecting computer stations to a plurality of communication devices, including the steps of receiving a connection request from a computer station to connect to a requested one of said plurality of communication devices, disconnecting the selected computer station from all of the communication devices, detecting if the selected computer station is configured according to the requested communication device, and connecting the selected computer station to the requested communication device, when the selected computer station is configured according to the requested communication device.
