CompTIA CASP+ (CAS-004) — Question 82

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 ׀׀¢ network?

Answer options

• A. Packets that are the wrong size or length
• B. Use of any non-DNP3 communication on a DNP3 port
• C. Multiple solicited responses over time
• D. Application of an unsupported encryption algorithm

Correct answer: B

Explanation

The correct answer is B because DNP3 is a specific protocol used in industrial control systems, and using non-DNP3 communication on its port can lead to vulnerabilities. Options A, C, and D are potential threats but do not specifically target the integrity of DNP3 communications, which is crucial for the security of the network in this scenario.
