In the coming weeks, we will publish an in-depth report about OPC and its various flavors, but for today, we want to share some details about a number of vulnerabilities that emerged from our intensive investigation of the protocol. The Claroty Research Team decided that due to its popularity as an embedded protocol operating in devices across the ICS domain, OPC was worthy of analysis for security vulnerabilities and implementation issues. Having standardized communication protocols such as OPC and its specifications (OPC DA, AE, HDA, XML DA, DX, and OPC UA) guarantees that management and oversight of devices and processes can happen from a centralized server.
The Open Platform Communications (OPC) network protocol is the middleman of operational technology (OT) networks, ensuring operability between industrial control systems (ICS) and proprietary devices, such as programmable logic controllers (PLCs) responsible for the correct operation of field devices.
