The energy sector is a crucial part of national infrastructure, encompassing the production, transmission, and distribution of electricity, oil, and natural gas. The rise of smart grids, renewable energy systems, and digital controls in Industrial Control Systems (ICS) has revolutionised this sector, but it also creates new cyber vulnerabilities. Cyberattacks like the 2015 Ukraine power grid attack demonstrated the devastating impact of breaches on energy infrastructure, leading to widespread blackouts and operational disruptions.
