Abstract
Physical One-way Transfer, one of network Separating Network Technologies, shut off intrusion possibilities by removing data transfer line from external network to internal network. Physical One-way Transfer technology can not support legacy services based duplex transmission. Legacy services operating need agent for extra service with the support. But, Agent development have problems with adding cost and open internal protocols. In this papers, We analyzed legacy services between Control network and OA network in working SCADA systems, and based on the results obtained from the analysis, categorized the legacy services into three forms. We propose an agent generation method of the three service categories for Physical One-Way Transfer System. In addition, we design an automatic generation tool using the proposed method.
