Answers
D.
It is an open source protocol.
Suggested answer: C

Explanation:

One of the known security concerns with the Distributed Network Protocol version 3 (DNP3), which is used in SCADA systems, is the lack of built-in security features, including authentication. This means that by default, it does not verify the identity of the entities communicating, making it susceptible to unauthorized access and commands.
