Power grid operators can now use virtual servers for critical systems

US regulators are updating rules for how power grid operators protect critical infrastructure. The new rules allow operators to use virtual servers and other modern technologies, which were previously restricted due to outdated security standards. This means grid operators can use more flexible and efficient IT systems while still meeting security requirements.

For years, power grid operators were stuck using older, less flexible hardware for their most critical systems because security rules hadn't caught up to modern technology. This made it harder to manage and update their infrastructure. The change means operators can now use virtualization, which allows multiple virtual servers to run on a single physical machine, making systems more efficient and easier to maintain. It also opens the door for other new technologies that rely on similar IT flexibility.
