Frank is a system administrator for a large network. His company has a large DNS
structure that he does not want to reveal to outsiders. He alters the SMTP headers
of all messages so that his users appear to be sending mails from a different address.
What is the name of process that Frank implemented?
A.
Aliasing.
B.
Masquerading.
C.
Forwarding.
D.
Relaying.
Explanation:
Masquerading is the proper technical term for the process of changing
SMPT headers to make the origins of the messages appear as if they came from a
different source.
Incorrect Answers:
A: Aliasing allows the use of nicknames, the address itself is not hidden in this process,so Frank
would not be able to hide anything but user information.
C: Forwarding will forward the messages, but the headers are preserved and Frank has nothidden
anything.
D: Relaying is when an intermediate mail server, or hub, is used to pass mail from serverto server.
Headers are preserved, so nothing is hidden and the original IP addresses anddomain names are
exposed.
