NSE 7 – OT Security 7.2 — Question 37

Which two of the following features do most industrial protocols lack? (Choose two.)

Answer options

• A. Real-time data exchange
• B. Deterministic timing
• C. TLS encryption
• D. Authentication

Correct answer: C, D

Explanation

Most industrial protocols focus on operational efficiency and real-time communication, often sacrificing security features like TLS encryption and authentication. While protocols may support real-time data exchange and deterministic timing, they typically do not implement encryption or robust authentication mechanisms.
