Securing OT/IT Systems for Power Industries
Power generation, transmission, and distribution systems — including renewable energy sources — are increasingly digitised and interconnected. This makes them attractive targets for cyber attackers seeking to disrupt national infrastructure or exploit vulnerabilities for geopolitical or financial gain. The consequences of a successful attack can be severe, from blackouts to equipment failure and public safety risks.
