Critical infrastructure cybersecurity covers sectors such as power, water, manufacturing, finance, communications and transportation. It protects information technology alongside operational systems whose failure can affect physical services and public safety.
Simultaneous or persistent attacks can create wider consequences than one isolated breach. Resilience therefore depends on prevention, monitoring, recovery planning and coordination among operators, technology providers and government bodies.

Critical infrastructure cybersecurity protects the computer and control systems behind essential services such as power, water, transport, finance, and communications. A failure in these systems can affect physical services and public safety.
For example, a water utility must protect both its office computers and the equipment that controls pumps and treatment. It also needs recovery plans so a successful attack does not stop safe water delivery for a long period.
