Ethical Hacking Essentials Practice Test

In which level of the Purdue model is the physical process analyzed and altered?

1. Level 0

2. Level 1

3. Level 2

4. Level 3

The correct answer is: Level 1

The correct choice refers to Level 1 of the Purdue model, which is specifically focused on the control systems that manage the physical processes in an industrial environment. In this level, real-time data from the physical operations are collected, and the systems through which these operations are monitored and controlled are analyzed and adjusted. This level is where the interaction between the physical processes and the control algorithms takes place, enabling the necessary alterations to improve efficiency, safety, and performance. While Level 0 deals with the physical processes themselves, such as the machinery and the operations they perform, it does not focus on the analysis or modification of these processes. Higher levels in the model, like Level 2 and Level 3, deal more with data aggregation and decision-making processes but do not engage directly with the physical process control as Level 1 does. Thus, it’s on Level 1 that specific adjustments to how the physical processes are managed occur.
