摘要：In this work, the features of the Defense-in-Depth (DID) concept of nuclear industry cyber security have been studied to obtain the insights of the DID architecture of server systems. Through the feature analysis, we have found out that there need to be clear system boundaries among all DID levels, systems should be classified by smaller scale, and one-way data flow makes it possible to assign a high cyber security level to a system. Based on the finding, we have suggested a DID architecture for server systems. The architecture is an n-tier and 'thin' server architecture which introduces the special features of the nuclear industry DID concept. The suggested architecture is expected to be very useful to improve the cyber security of various kinds of server systems.
