Development of hacking techniques demands more and more network security. For this reason, major facilities as well as government agencies divide the protected network from internet network physically. However, if internal/external network is divided, file transfer and work efficiency is reduced. To solve this problem and to transfer data between the internet network and protected network, unidirectional security gateway system was born. This paper analyzes unidirectional security gateway and suggests a protection profile based on the CC V3.1 to help develop and evaluation of unidirectional security gateway.
