Question 46/103
Which of the following OT protocols sends information in cleartext?
Correct Answer: C
Operational Technology (OT) protocols are used in industrial control systems (ICS) to manage and automate physical processes. Here's an analysis of each protocol regarding whether it sends information in cleartext:
* TTEthernet (Option A):
* Explanation: TTEthernet (Time-Triggered Ethernet) is designed for real-time communication and safety-critical systems.
* Security: It includes mechanisms for reliable and deterministic data transfer, not typically sending information in cleartext.
* DNP3 (Option B):
* Explanation: DNP3 (Distributed Network Protocol) is used in electric and water utilities for SCADA (Supervisory Control and Data Acquisition) systems.
* Security: While the original DNP3 protocol transmits data in cleartext, the DNP3 Secure Authentication extensions provide cryptographic security features.
* Modbus :
* Explanation: Modbus is a communication protocol used in industrial environments for transmitting data between electronic devices.
* Security: Modbus transmits data in cleartext, which makes it susceptible to interception and unauthorized access.
