A filter module allows controlling network security by specifying security rules for traffic in the network and accepting or dropping communication packets according to these security rules. A set of security rules are defined in a high level form and are translated into a packet filter code. The packet filter code is loaded into packet filter modules located in strategic points in the network. Each packet transmitted or received at these locations is inspected by performing the instructions in the packet filter code. The result of the packet filter code operation decides whether to accept (pass) or reject (drop) the packet, disallowing the communication attempt.
