Cybersecurity: Developing foolproof security measures against cyberattacks, ensuring data privacy, and creating secure communication protocols in the face of advancing threats such as quantum computing attacks and AI-driven cyber threats are ongoing challenges.

A security architect for a large, multinational manufacturer needs to design and implement a security solution to monitor traffic.

When designing the solution, which of the following threats should the security architect focus on to prevent attacks against the OT network?

1. Packets that are the wrong size or length
2. Use of any non-DNP3 communication on a DNP3 port
3. Multiple solicited responses over time
4. Application of an unsupported encryption algorithm

B, C or D which one is correct ???
