  • defining a set of symbols that identify logical operations that can be carried out by the network device;

    defining an information communication policy for the network device by graphically interconnecting one or more of the symbols into a symbolic representation of the policy; and

    generating a set of instructions based on the symbolic representation of the policy, wherein the set of instructions causes the network device to selectively pass or reject messages according to the policy, comprising the steps of generating a source script that defines the policy in a scripting language; and
