Question

Performing a penetration test against an environment with SCADA devices brings an additional safety risk because the:

Answers
  1. correct
Explanation

Correct Answer: D. Devices may cause physical world effects.

SCADA (Supervisory Control and Data Acquisition) systems control industrial processes and critical infrastructure, such as:

  • Power plants
  • Water treatment facilities
  • Manufacturing systems
  • Traffic control systems

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:

  • Power grid failures
  • Water supply contamination
  • Gas pipeline explosions
  • Malfunctioning industrial equipment

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.

  • The primary concern is physical world disruption, not power consumption.

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.

  • The biggest risk is that a test could disrupt or damage critical infrastructure, causing real-world consequences.

Protocols are more difficult to understand.

  • Many SCADA protocols (MODBUS, DNP3, BACnet) are simpler than modern IT protocols.

  • Complexity is not the main risk—the primary issue is that testing these systems can lead to real-world physical effects.
