N2 - OPC UA is widely adopted for remote-control in industrial environments. It has a central role for industrial control systems as it enables remote management. Compromising OPC UA can lead to compromising entire production facilities. Consequently, OPC UA requires a high level of security. Major commercial OPC UA implementations have compliance certificates ensuring that their security models obey the specification. However, open-source OPC UA implementations that have wide deployment mostly lack these certificates. In this work, we investigate the security models of the four most commonly used open-source implementations: open62541, node-opcua, UA-.NETStandard, and python-opcua. Furthermore, their scalabilities for the number of clients and OPC UA nodes are also analyzed.
