1. Which type of malware can copy itself and infect a computer without the user’s consent or knowledge?
a) virus
b) Trojan horse
c) rootkit
d) backdoor
Definition
Answer: a
Difficulty: Easy
Section Reference: Looking at Types of Malware
Explanation: A computer virus is a program that can copy itself and infect a computer without the user’s consent or knowledge. Early viruses were usually some form of executable code that was hidden in the boot sector of a disk or as an executable file (that is, a filename with an .exe or .com extension). Later, viruses mutated enough to affect data documents that included macro languages.
Term
2. What type of self-replicating program copies itself to other computers on a network without any user intervention and consumes bandwidth and computer resources?
a) virus
b) Trojan horse
c) worm
d) backdoor
Definition
Answer: c
Difficulty: Medium
Section Reference: Looking at Types of Malware
Explanation: A worm is a self-replicating program that copies itself to other computers on a network without any user intervention. Unlike a virus, a worm does not corrupt or modify files on the target computer. Instead, it consumes bandwidth and processor and memory resources, slowing the system down or causing it to be unusable. Worms usually spread via security holes in operating systems or TCP/IP software implementations.
Term
3. What malware looks like a useful or desired executable program but is in reality program that is supposed to cause harm to your computer or steal information from your computer?
a) virus
b) Trojan horse
c) worm
d) backdoor
Definition
Answer: b
Difficulty: Easy
Section Reference: Looking at Types of Malware
Explanation: A Trojan horse is an executable program that appears as a desirable or useful program. Because it appears to be desirable or useful, users are tricked into loading and executing it on their systems. After the program is loaded, it might cause a user’s computer to become unusable, or it might bypass the user’s system security, allowing private information (including passwords, credit card numbers, and Social Security numbers) to be accessible by an outside party. In some cases, a Trojan horse may even execute adware.

Therefore, you need to take steps to ensure that this information cannot be read or used without your knowledge. A cookie is a piece of text stored by a user’s web browser. To clean out history, temporary files, and cookies, open the Internet Options and select the General tab.
Term
16. Which Internet Explorer zone is the least secure?
a) Internet zone
b) local intranet zone
c) trusted sites zone
d) restricted sites zone
Definition
Answer: b
Difficulty: Hard
Section Reference: Examining Content Zones
Explanation: The trusted sites zone contains sites from which you believe you can download or run files without damaging your system. You can assign sites to this zone. The default security level for the trusted sites zone is Low, which means Internet Explorer will allow all cookies from websites in this zone to be saved on your computer and read by the website that created them. The next least secure is the local intranet, which is configured as Medium-Low.
Term
17. What technique is used to send you to a fake, but realistic-looking, website to verify your account information?
a) spoofing
