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. 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. Please identify what type(s) of new countermeasures should have been implemented to prevent this cyber attack from occurring.

Start a discussion thread and discuss what type(s) of new countermeasures should have been implemented to prevent the cyber attack described above from occurring. Be specific in recommending countermeasures for this scenario.
