Abstract
A system for controlling Signaling System #7 (“SS7”) message traffic by defining a message control policy for SS7 signaling links and accepting, modifying, responding to, or rejecting SS7 signaling messages according to the defined control policy is disclosed. The control policy is composed of a set of access rules that are loaded onto one or more firewalls located at strategic points in a SS7 network. The firewalls use the access rules as the basis for examining each SS7 message a signaling node transmits or receives on a signaling link and determining whether or not to pass, modify, respond to, or reject the message. The system includes a graphical user interface for providing configuration information, as well as information as to the current and past states of the message traffic of a signaling node.
