Protecting Critical Infrastructure

Critical infrastructure was built to keep operating.

Water treatment plants, power generation sites, electrical substations, traffic control systems, rail networks, ports, airports, and emergency services were designed around availability, safety, reliability, and continuity. In many cases, the systems that run them were built long before today’s threat environment existed.

That creates a difficult problem. The systems society depends on most are often the hardest to change. A PLC running part of a water treatment process may be too old to support modern security software. A substation device may be under warranty, certified, or too operationally sensitive to modify. A traffic control system may rely on equipment designed to communicate within a trusted municipal network, not across today’s connected infrastructure.

Security teams know these systems need stronger protection. Operators know they cannot risk disrupting them.
