Certified Information Systems Auditor (CISA) — Question 826

An IS auditor is reviewing the business requirements for the deployment of a new website. Which of the following cryptographic systems would provide the BEST evidence of secure communications on the Internet?

Answer options

• A. Transport Layer Security (TLS)
• B. Wi-Fi Protected Access 2 (WPA2)
• C. IP Security (IPSEC)
• D. Secure Shell (SSH)

Correct answer: A

Explanation

Transport Layer Security (TLS) is the best choice because it is specifically designed to secure communications over the internet by encrypting data during transmission. While WPA2 secures wireless networks, IPSEC is used for securing Internet Protocol communications and SSH is primarily used for secure remote logins, neither of them is focused solely on securing web communications like TLS.
