CompTIA SecurityX (CAS-005) — Question 12

PKI can be used to support security requirements in the change management process. Which of the following capabilities does PKI provide for messages?

Answer options

• A. Non-repudiation
• B. Confidentiality
• C. Delivery receipts
• D. Attestation

Correct answer: A

Explanation

Non-repudiation is a key feature of PKI, ensuring that the sender cannot deny sending a message, which is crucial for accountability in change management. While confidentiality protects the message's content, delivery receipts and attestation do not directly relate to the core capabilities provided by PKI.
