Vulnerability Management in OT: Why Is Patching Devices in the Power Grid So Difficult?

The European power grid is an attractive target for attacks. Substations and power plants offer the largest attack surface. This is because thousands of protection and control devices communicate here, control high-voltage lines and secure grid operation. Grid operators are often unaware of how many publicly known vulnerabilities exist in their systems. Targeted patching of devices with a clear focus on the truly relevant security gaps could remedy this situation. Why, then, do many energy suppliers still not do this?ISAGCARead More
