ABSTRACT:
A system, method and apparatus for securing communications between a trusted network and an untrusted network are disclosed. A perimeter client is deployed within the trusted network and communicates over a session multiplexing enabled protocol with a perimeter server deployed within a demilitarized zone network. The perimeter client presents requests to make available and communication initiation requests to the perimeter server which presents corresponding sockets to the entrusted network. The session multiplexing capabilities of the protocol used between the perimeter server and perimeter client permit a single communication session therebetween to support a plurality of communication sessions between the perimeter server and untrusted network. In the event data flows across the communication sessions are encrypted, decryption of the data flows is left to the components at the end points of the communication session, thereby restricting exposure of privileged information to areas within trusted networks.
