In August, cyber attackers breached small water utility systems in Colorado, manipulating not only the control systems but also the safety processes. This incident, unlike others, did not impact water quality or public safety, yet it raises significant concerns. The attackers altered pumping cycles and equipment settings, and critically, they disabled alarms. Alarms serve as essential safeguards, alerting operators to abnormal process behaviors. The breach underscores the need for heightened security measures to protect these safeguards, which are as vital as the systems they monitor. Ensuring the integrity of alarm systems is crucial to maintaining operational safety and preventing potential hazards.
