Network Security Policy Compiler (NetSPoC) is a tool for security management of large networks with different security domains. It generates configuration files for packet filters controlling the borders of security domains. It provides its own language for describing security policy and the topology of a network. The security policy is a set of rules that state which packets are allowed to pass the network and which are not. NetSPoC is topology aware - a rule for traffic from A to B is automatically applied to all managed packet filters on the path from A to B.
