Selected Answer: D
In Industrial Automation and Control Systems (IACS) environments, Programmable Logic Controllers (PLCs) play a critical role in controlling physical processes such as manufacturing, energy production, or water treatment. If a cyber attack compromises a PLC: • It can disrupt operations, leading to financial losses due to production downtime. • It can create safety hazards that endanger personnel, equipment, and the environment. • It can damage critical infrastructure, causing long-term consequences. Ensuring network security in IACS environments is essential to protect PLCs from unauthorized access, tampering, or attacks that could result in costly and dangerous impacts.
