CIS1200 UNIT 9 EXAM QUESTIONS WITH ANSWERS
100% SOLVED
When a hacker steals personal information with the intent of impersonating another
individual to commit fraud, it is known as - ANSWER identity theft.
Identity theft occurs when a thief steals personal information such as your name,
address, Social Security number, birth date, bank account number, and credit card
information and poses as you in financial or legal transactions. Theft of personal data
such as bank account numbers and credit/debit card numbers is of most concern to
individuals because this information is usually used for fraudulent purposes. Many
victims of identity theft spend months, or even years, trying to repair their credit and
eliminate fraudulent debts.
An attack that renders a computer unable to respond to legitimate users because it is
being bombarded with data requests is known as a _______ attack. - ANSWER
denial-of-service
In a denial-of-service (DoS) attack, legitimate users are denied access to a computer
system because a hacker is repeatedly making requests of that computer system
through a computer he or she has taken over as a zombie. A computer system can
handle only a certain number of requests for information at one time. When it's flooded
with requests in a DoS attack, it shuts down and refuses to answer any requests, even if
the requests are from a legitimate user. Thus, the computer is so busy responding to the
bogus requests for information that authorized users can't gain access.
A computer virus is like a biological virus because - ANSWER it attaches to a host and
then spreads to other victims.
they can both be difficult to exterminate.
they are easy to catch.
all of the above
A computer virus is a computer program that attaches itself to another computer
, program (known as the host program) and attempts to spread to other computers when
files are exchanged. That behavior is very similar to how biological viruses spread,
giving this type of threat its name.
A series of commands that are executed without your knowledge is a typical attribute of
a(n) ____________ virus. - ANSWER script
Some viruses are hidden on websites in the form of scripts. A script is a series of
commands—actually, a mini-program—that is executed without your knowledge. Scripts
are often used to perform useful, legitimate functions on websites, such as collecting
name and address information from customers. However, some scripts are malicious.
For example, you might click a link to display a video on a website, which causes a script
to run that infects your computer with a virus.
Software that pretends your computer is infected with a virus to entice you into
spending money on a solution is known as - ANSWER scareware.
Scareware is a type of malware that downloads onto your computer and tries to
convince you that your computer is infected with a virus or other type of malware.
Pop-ups, banners, or other annoying types of messages will flash on your screen, saying
frightening things like "Your computer is infected with a virus ... immediate removal is
required." You're then directed to a website where you can buy fake removal or
antivirus tools that provide little or no value. Some scareware even goes so far as to
encrypt your files and then demand that you pay to have them unencrypted, which is
essentially extortion.
Firewalls work by closing ____ in your computer. - ANSWER logical ports
Firewalls are designed to restrict access to a network and its computers. Firewalls
protect you in two major ways: (1) by blocking access to logical ports, and (2) by
keeping your computer's network address secure. Recall that logical ports are virtual
communications paths that allow a computer to organize requests for information from
other networks or computers.
Antivirus software looks for ____ to detect viruses in files. - ANSWER virus signatures
