You have been hired at a large company to manage network security issues. Prior to your arrival, there was no one dedicated to security, so you are starting at the beginning. You hold a meeting and are discussing the main functions and features of network security. One of your assistants asks what the function of Authentication in network security is. Which of the following best describes Authentication?

A.
Data communications as well as emails need to be protected for privacy and Authentication.
Authentication ensures the privacy of data on the network system.

B.
Authentication is a security principle that ensures the continuous accuracy of data and information stored within network systems. Upon receiving the email or data communication, authentication must be verified to ensure that the message has not been altered, modified, or added to or subtracted from in transit by unauthorized users.

C.
The security must limit user privileges to minimize the risk of unauthorized access to sensitive information and areas of the network that only authorized users should only be allowed to access.

D.
Security must be established to prevent parties in a data transaction from denying their participation after the business transaction has occurred. This establishes authentication for the transaction itself for all parties involved in the transaction.

E.
Authentication verifies users to be who they say they are. In data communications, authenticating the sender is necessary to verify that the data came from the right source. The receiver is authenticated as well to verify that the data is going to the right destination.
