Certified Information Systems Security Professional (CISSP) — Question 113

Which of the following would be the BEST mitigation practice for man-in-the-middle (MITM) Voice over Internet Protocol (VoIP) attacks?

Answer options

• A. Use Secure Shell (SSH) protocol
• B. Use File Transfer Protocol (FTP)
• C. Use Transport Layer Security (TLS) protocol
• D. Use Media Gateway Control Protocol (MGCP)

Correct answer: C

Explanation

Using Transport Layer Security (TLS) protocol is the best mitigation practice as it encrypts the communication, making it difficult for attackers to intercept or alter the data. In contrast, Secure Shell (SSH) is primarily used for secure remote access, File Transfer Protocol (FTP) lacks encryption, and Media Gateway Control Protocol (MGCP) does not provide sufficient security measures against MITM attacks.
