You
are the Network Administrator for a bank. In addition to the usual security issues, you are concerned
that your customers could be the victim of phishing attacks that use fake bank Web sites. Which of
the following would protect against this?

A.
MAC

B.
Mutual authentication

C.
Three factor authentication

D.
Two factor authentication

Explanation:
In mutual authentication not only does the server (in this case the banks Web server)
authenticate the client, but the client authenticates the
server. For example some banks now have a user pick an image and a phrase that is stored. When
they enter their user name, the bank Web
site will display their pre-selected image and phrase, before the user enters their password. If the
user does not see their unique
image/phrase combination, then this is not really the bank Web site.
