Question 1

An intentional action designed to prevent legitimate users from making use of a computer service is called
A) a bombing run.
B) a curtain closer.
C) a denial-of-service attack.
D) an electronic overdose.
E) phreaking.

Accepted Answer

A denial-of-service attack (DoS attack) is an intentional action aimed at preventing legitimate users from making use of a computer service. It involves overwhelming the targeted service or network with a flood of internet traffic or a series of requests, which results in it becoming unavailable to users.

Question 2

The Conficker worm is notable because
A) it is Cuba's first attempt at cyberwarfare.
B) it is the fastest spreading worm of all time.
C) it shut down the White House Web site for three days.
D) computer experts have found it particularly difficult to eradicate.
E) All of the above.

Accepted Answer

The Conficker worm is particularly difficult to eradicate, leading computer experts to work tirelessly to find ways to remove it from infected systems. While it did cause disruptions and damage, it did not shut down the White House website for three days nor is it Cuba's first attempt at cyberwarfare. While it did spread rapidly, it is not the fastest spreading worm of all time.

Question 3

Accepted Answer

denial-of-service DoS attack

Question 4

Determining that a person is who he or she claims to be on a computer is called
A) accountability.
B) authentication.
C) authorization.
D) debugging.
E) social engineering.

Accepted Answer

The process of determining that a person is who he or she claims to be on a computer is known as authentication. It involves verifying the identity of a user typically by requiring a username and password combination, but can also involve more advanced methods such as biometric identification.

Question 10

The process of determining that a user has permission to perform a particular action on a computer is called
A) accountability.
B) authentication.
C) authorization.
D) debugging.
E) social engineering.

Accepted Answer

The process of determining whether a user has the necessary permissions to perform a specific action on a computer is called authorization. Authentication is the process of verifying the identity of a user, while accountability is the process of tracking an individual's actions on a system. Debugging refers to the process of locating and fixing errors in computer code, and social engineering involves using psychological manipulation to trick individuals into divulging sensitive information.

Question 12

A self-contained program that spreads through a computer network by exploiting security holes is called a
A) hack.
B) rogue.
C) Trojan horse.
D) virus.
E) worm.

Accepted Answer

A self-contained program that spreads through a computer network by exploiting security holes is called a worm. Unlike viruses, worms do not need to attach themselves to a program or file to spread. They can spread on their own and can cause significant damage to a network by consuming bandwidth and overloading servers.

Question 16

A program with a benign capability that conceals another, sinister purpose is called a
A) hack.
B) rogue.
C) Trojan horse.
D) virus.
E) worm.

Accepted Answer

A Trojan horse is a program that appears harmless but actually has malicious intent. It can be used to gain unauthorized access to information or systems, steal data, or cause damage to the system. The other options are types of malware that are designed to cause harm or damage, but do not necessarily conceal their true purposes.

A piece of self-replicating code embedded within another program is called a
A) hack.
B) rogue.
C) Trojan horse.
D) virus.
E) worm.

Accepted Answer

A virus is a type of malware that replicates itself by inserting its code into other programs or files. This allows it to spread to other computers or systems, often causing damage or stealing data. Other choices are not specific to self-replicating code, such as a hack or rogue, or refer to a specific type of malware that may not necessarily have self-replicating capabilities, such as a Trojan horse or worm.
