CompTIA CySA+ (CS0-003) — Question 182

An analyst is designing a message system for a bank. The analyst wants to include a feature that allows the recipient of a message to prove to a third party that the message came from the sender.

Which of the following information security goals is the analyst most likely trying to achieve?

Answer options

• A. Non-repudiation
• B. Authentication
• C. Authorization
• D. Integrity

Correct answer: A

Explanation

The correct answer is A, Non-repudiation, as it ensures that the sender cannot deny having sent the message, thus providing proof to a third party. Authentication relates to verifying the identity of the sender, while Authorization involves permissions and rights, and Integrity ensures the message has not been altered.
