NSE 7 – OT Security 7.2 — Question 29

As an OT network administrator, you are managing three FortiGate devices that each protect different levels on the Purdue model. To increase traffic visibility, you are required to implement additional security measures to detect protocols from PLCs.

Which security sensor must you implement to detect protocols on the OT network?

Answer options

• A. Application control (AC)
• B. Endpoint Detection and Response (EDR)
• C. Deep packet inspection (DPI)
• D. Intrusion prevention system (IPS)

Correct answer: A

Explanation

The correct answer is A, Application control (AC), because it is designed to monitor and manage application usage, allowing you to detect specific protocols used by PLCs. The other options, while important security measures, do not specifically focus on protocol detection in the same way that application control does.
