How governments and the nuclear energy industry are preparing for future cybersecurity threats using hands-on exercises and training laboratories

Context & Ripple Effects
This piece lands on top of two threads the desk has been tracking. The first is the exposure side: reporting on the vulnerability of the nuclear command-and-control system documented how obsolete hardware and software leave the most sensitive nuclear systems running on aging technology. The second is the rehearsal side: NATO's Locked Shields war games, where 19 teams practiced defending national infrastructure, established the template for large-scale defensive exercises.
What changes here is who is doing the training: rather than militaries and national CERTs alone, governments and the commercial nuclear energy industry are building hands-on exercises and dedicated training laboratories, bringing plant operators into the same preparedness loop.
First-order effects
- Nuclear plant operators move from paper-based security assessments to rehearsing attack scenarios in training laboratories, testing incident response against simulated threats before a real incident forces it.
Second-order effects
- Exercise formats proven at scale in Locked Shields become the model other critical-infrastructure sectors copy, pulling utilities, regulators, and vendors into recurring multinational drills.
Third-order effects
- If the pattern holds, critical-infrastructure security shifts structurally from periodic compliance checks toward continuous, exercised readiness — with shared training ranges becoming standing infrastructure that governments fund the way they fund physical drills.
The trend: Critical-infrastructure cyber defense is shifting from static audits toward recurring live-fire exercises and shared training laboratories, with the nuclear sector as an early adopter.
