Which of the following guarantees that the sender cannot repudiate, or refute, the validity of a message sent?
- Data nonrepudiation

Explanation: Data nonrepudiation guarantees that the sender cannot repudiate, or refute, the validity of a message sent. An exploit is a mechanism that takes advantage of a vulnerability. Mitigation is a countermeasure to eliminate or reduce the potential of a threat or risk. Origin authentication guarantees that a message is not a forgery and does actually come from the person who is supposed to have sent it.
