An efficient intranet architecture scheme based on regional function and security requirement in semiconductor manufacturing enterprises

The use of information and communication technologies is growing rapidly [1], and information security requirements have risen to a new stage. When IC production enters into the nanometer generation, more and more semiconductor manufacture companies have taken a lot of effort in information security area to prevent company information security, especially at the network level. The network structure of the semiconductor manufacturing enterprise is complicated due to huge organizational structure, and there are easily potential risks come from threat or attack to network. In this paper, and a good practice of internal area network solution is presented. In order to guarantee the security of customer IC design data and foundry process knowledge, an effective functional security zones scheme is designed to enhance the security level of intranet and at the same time not to affect operation convenience and efficiency.
