Performing a penetration test against an environment with SCADA devices brings an additional safety risk because the:
Correct Answer: D. Devices may cause physical world effects.
SCADA (Supervisory Control and Data Acquisition) systems control industrial processes and critical infrastructure, such as:
Unlike traditional IT systems, SCADA devices directly interact with the physical world. If a penetration test disrupts or crashes these systems, it could lead to real-world consequences, such as:
Because of these high-stakes risks, penetration testing against SCADA must be carefully planned to avoid causing unintended physical harm or service disruptions.
Why the Other Options Are Incorrect:
Devices produce more heat and consume more power.
SCADA devices do not inherently produce excessive heat or power compared to other IT equipment.
Devices are obsolete and are no longer available for replacement.
While many SCADA systems run on legacy hardware/software, their replacement difficulty is not the primary safety concern.
Protocols are more difficult to understand.
Many SCADA protocols (MODBUS, DNP3, BACnet) are simpler than modern IT protocols.
