Certified Information Systems Auditor (CISA) — Question 637

Which of the following is the PRIMARY protocol for protecting outbound content from tampering and eavesdropping?

Answer options

• A. Internet Key Exchange (IKE)
• B. Secure Shell (SSH)
• C. Point-to-Point Protocol (PPP)
• D. Transport Layer Security (T LS)

Correct answer: D

Explanation

Transport Layer Security (TLS) is designed specifically to protect data transmitted over networks, ensuring confidentiality and integrity. While Internet Key Exchange (IKE), Secure Shell (SSH), and Point-to-Point Protocol (PPP) serve important security functions, they do not primarily focus on securing outbound content in the same comprehensive manner as TLS.
