2. What was the Code Red Virus?
 The Code Red worm was a computer worm
observed on the Internet on July 13, 2001. It
attacked computers running Microsoft’s II web
server.

3. What was the “Love Bug” Virus? What
damage did it do
 A new computer virus spread around the world
recently with a vengeance. This virus traveled via e-
mail messages entitled quot;I Love You,quot; crippling
government and business computers in Asia, Europe,
and the United States. No immediate cure was
known as experts were stunned by the speed and
wide reach of the virus.

4. What is Biometric Computer Security?
 biometric computer security system requires the user to
provide a fingerprint (or other biometric) to the system, which
is then verified against a stored biometric template. Because
fingerprints offer an additional factor of authentication, i.e.,
something you are, in addition to something that you know
(password), or have (token), biometric security systems offer
significant improvements over traditional computer security.

5. Give an example of Phishing Scheme?
 Always remember, companies like Google, eBay or
Amazon will never send you an email asking for
account details and most companies will never send
you an insecure (http://) link instead of a secure
(https://) link.

6. What are 3 advantages of Biometric
Security?
 Three Advantages Include:
 A. Will give you 100% accuracy and cant be hacked
by anyone.
 B. Many different types including physical, and
behavioral.
 C. Tougher to steal the information
 D. Cheap

7. 2 disadvantages of Biometric Security
 Expensive
 Invasion of privacy

8. How does Anti Virus Software combat
Viruses? 陿蚟陿翿
computer software used to
 Antivirus software (or anti-virus) is
identify and remove computer viruses, as well as many other
types of harmful computer software, collectively referred to as
malware. While the first antivirus software was designed
exclusively to combat computer viruses, most modern antivirus
software can protect against a wide range of malware, including
worms, rootkits, and Trojans.

9. What type of information should be
encrypted? 3 Examples
encryption is the process of transforming

information (referred to as plaintext) using
an algorithm (called cipher) to make it
unreadable to anyone except those
possessing special knowledge, usually
referred to as a key. The result of the
process is encrypted information (in
cryptography, referred to as ciphertext). In
many contexts, the word encryption also
implicitly refers to the reverse process,
decryption (e.g. “software for encryption”
can typically also perform decryption), to
make the encrypted information readable
again (i.e. to make it unencrypted).
