Development of cyber-physical security testbed based on IEC 61850 architecture

Abstract

The paper focuses on security in industrial control systems. Numerous protocols and their incompatibility are undermining the security design. Also, the IEC 61850 standard focuses on these issues. In detail, it deals with the compatibility between protocols and, partly, security. In the context of this work, a testbed together with the traffic generator for IEC 61850 standard and its three main parts - MMS (Manufacturing Message Specification), GOOSE (Generic Object-Oriented Substation Events), and Sampled Values - are designed. Additionally, the used generator is compared with an example of RTU (Remote Terminal Unit) used in standard ICS (Industrial Control Systems) networks. The last part of this work consists of the performance testing of the implemented protocols (MMS, GOOSE, and Sampled Values).
