A common breach of network security is the class of attacks called Worm-virus. This paper proposes a language called Triton whose goal is to efficiently and effectively safeguard large network security for management system. We represent abstract language that supports varitions. This high-level language abstracts the control behavior of the network nodes, which has various setting-up methodology. We shall describe the feature of Triton language and give some example of the preliminary Triton implementation on the test-bed.
