Critical Infrastructure Cyber Security refers to the protection of essential systems such as energy, water, transportation, communications, healthcare, and financial services that ensure a country’s economic, social, and military continuity against digital threats. As these infrastructures are now largely managed through digital networks and automated systems, they have become prime targets for cyber attacks. Scenarios such as widespread power outages, disruption of water supplies, paralysis of transportation systems, or collapse of communication networks are no longer considered merely technical failures, but strategic risks that directly threaten national security and public order. For this reason, securing critical infrastructures has become one of the top priorities of modern states.

From a more technical perspective, Critical Infrastructure Cyber Security encompasses the protection of industrial control systems (ICS), SCADA infrastructures, IoT-based sensors, and centralized data management platforms. Unlike traditional information technologies, these systems must operate continuously without interruption, which requires specially designed cyber defense strategies. Real-time threat monitoring, anomaly detection, artificial intelligence–driven attack analysis, and rapid incident response mechanisms form the backbone of this security architecture. In addition, regular cyber drills and comprehensive risk assessments significantly enhance preparedness against potential attack scenarios. Today, critical infrastructure cyber security is no longer just a technical necessity, but a fundamental security element that provides deterrence, resilience, and strategic superiority in the digital era.
