QuestionQ16

Security Engineering

A water treatment plant uses specialized systems to manage the chemical balance before those chemicals are added to the public water supply. The plant has already isolated the system from both the internet and the company network. Which additional control best reduces the risk of a successful attack?

  • A Implementing two-person control procedures
  • B Developing insider threat training
  • C Storing the chemicals behind locked doors
  • D Maintaining calibration of the chemical sensor system
Explanation

Two-person control prevents a single authorized individual from independently performing sensitive actions on the chemical-control system. This directly reduces the risk of insider misuse or compromise of an isolated operational system.
