Summary:
In the era of Industry 4.0 (I4.0) Cyber-Physical Systems (CPS) are pivotal in enhancing industrial processes by using the Open Platform Communication Unified Architecture (OPC-UA) as the standard communication protocol. OPC-UA is one of the few industrial protocols that incorporates security measures for preventing adversaries from compromising critical infrastructures. However despite the protocol’s security features and widespread adoption it continues to reveal cybersecurity challenges and setup vulnerabilities in several products and vendor implementation libraries. Many vendor implementations of OPC-UA are unaware of the security risks associated with non-compliance to the OPC-UA specification or the integration of OPC-UA with other insecure protocols. Therefore this work demonstrates the weaknesses of OPC-UA in such vendor implementation contexts by analyzing the communication architecture of the adopted OPC-UA library. Specifically we start by simulating a communication architecture set-up that mimics most vendor OPC-UA implementations which includes Digital Twin Cobots Manufacturing Execution Systems (MES) and Enterprise...Author(s):
