Abstract

A flexible network security system and method permit a trusted process through a firewall. The system includes a port monitoring unit for extracting information about a server port being used through a network communication program, an internal permitted program storage configured to store a list of programs permitted by the firewall, and a firewall flexible device configured to add the network communication program to the list of programs by extracting information about the network communication program and to automatically store the extracted information about the server port in an internal port storage if the network communication program tries to listen to the server port. The firewall flexible device is further configured to determine whether a port of a packet of inbound traffic matches the server port and to allow the packet of inbound traffic if the port matches the server port.
