This defense in depth discussion scenario is an intentional cybersecurity attack on the water utility’s SCADA system. It occurs during the fall after a dry summer in Fringe City.
Scenario:
The water utility’s Information Technology (IT) person did not receive an expected pay raise and decides to reprogram the SCADA system to shut off the high-lift pumps. The operator’s familiarity with the SCADA system allows him to reprogram the alarms that typically notify operators of a high-lift pump failure. In addition, he prevents access to the SCADA system by others. A wildfire breaks out on the outskirts of the city.
Task:
Please identify what type(s) of new countermeasures should have been implemented to prevent this cyber-attack from occurring.
