Which of the following is a process in which data is changed before or while it is entered into a
computer system?
A.
Data diddling
B.
Authentication
C.
Domain kiting
D.
Packet sniffing
Explanation:
Data diddling is a process in which data is changed before or while it is entered into a computer
system. A malicious code or virus can perform data diddling. For example, a virus can be written to
intercept keyboard input. The virus displays the appropriate characters on the computer screen so
that the user does not know the actual problem.Answer C is incorrect. Domain kiting is a process whereby a user registers a domain (usually one
with a prominent sounding name likely to attract significant traffic), and on that domain, he puts up
a page with a lot of click through ads (the ads that pay the owner of the Web site for all clicks).
During this process, the user who registered the domain cancels it before the normal grace period is
over and then re-registers it again. This process is repeated any number of times with the end result
of having the domain registered without ever actually paying for it.Answer B is incorrect. Authentication is a process of verifying the identity of a person, network host,
or system process. The authentication process compares the provided credentials with the
credentials stored in the database of an authentication server.Answer D is incorrect. Packet sniffing is a process of monitoring data packets that travel across a
network. The software used for packet sniffing is known as sniffers. There are many packet-sniffing
programs that are available on the Internet. Some of these are unauthorized, which can be harmful
for a network’s security.
