We tend to think that critical systems responsible for managing oil rigs, power stations, steel production plants, are somewhat immune to what happens in the “wild west” of cyberspace. News of cyberattacks tend to focus on data theft, financial heists, or bringing down websites; they are contained within IT systems. If cyberattacks are contained in the cyber world, then the logic goes that only cyber insurers should be concerned by the risk.
There is also a sense of security in the belief that critical control systems for “real world” assets and processes would either be too mechanical, too old, not connected to the same network as the wider Internet, or would run on their own networks. The reality is that industrial control systems (ICS) that manage energy, water, transport, communications, and manufacturing plants, are increasingly managed and controlled remotely or need to be networked. Wherever the systems need to use a network, the systems are exposed to vulnerabilities on that network. For non-cyber insurers, this risk needs to be assessed and managed.
