A user has been accused of hacking into a server. Which of the following would keep him from denying that he did it?

Question

Group of answer choices

Authentication

Authorization

Accounting

Nonrepudiation

Answer 1

The correct answer is Nonrepudiation.

Nonrepudiation refers to the assurance that someone cannot deny the validity of something. In the context of hacking into a server, if there are mechanisms in place for nonrepudiation (such as logs of actions taken, digital signatures, or audit trails), it would provide evidence that the user indeed accessed the server, making it difficult for the user to deny their involvement.

While Authentication refers to verifying the identity of a user, Authorization involves granting permission to access resources, and Accounting tracks user activities, nonrepudiation specifically addresses the issue of denying an action after it has been performed.
