Which of the following is a benefit of using Kerberos for authentication?

The benefit of using Kerberos for authentication primarily lies in its strong mutual authentication feature. In a Kerberos environment, both the client and the server verify each other's identities before a secure connection is established. This mutual authentication is achieved through a system of ticket-granting tickets (TGTs) and service tickets, which are encrypted with secrets known only to the Kerberos server and the user or service.

This process not only helps in confirming that the client is communicating with the intended server but also ensures that the server can trust that the request is coming from a legitimate client. The strength of Kerberos stems from its cryptographic protections and the fact that it mitigates certain types of attacks, such as replay attacks, by using timestamps and session keys.

While some of the other choices might touch on aspects related to Kerberos (like being able to integrate across platforms), the primary strength attributed to Kerberos is its robust mutual authentication mechanism that enhances overall security in networked environments.
