ABSTRACT:
A network connection blocker for monitoring connections between host computers in a network and blocking the unwanted connections. The host computers transmit connection packets between each other in accordance with a network protocol suite when seeking to establish, providing network services with, and close the connections. The network protocol suite includes a connection oriented transport layer protocol. The network connection blocker comprises a network interface that receives the connection packets transmitted between the host computers. It also comprises a blocking module that processes the received connection packets to detect the unwanted connections. The blocking module then generates connection packets in accordance with the network protocol suite to cause the detected unwanted connections to be closed by the corresponding host computers between which are the unwanted connections. The network interface then transmits the generated connection packets to these host computers.
