Accepted Answer

Spoofing is not a common motive for DDoS attacks as it doesn't provide any direct benefit to the attacker. The other options - political anger, extortion, and negative recognition - are all more likely motives for a DDoS attack. Political anger may drive individuals or groups to attack websites associated with governments or political parties. Extortion may involve an attacker demanding payment in exchange for not disrupting a website's operations. Negative recognition may involve an attacker seeking attention or validation through disrupting a website or network.

C)The police use a virus and other measures to take down a network of computer criminals.
D)A zombie army is used to attack computers or computer networks.

Accepted Answer

During a DDoS (Distributed Denial of Service) attack, a group of computers (a "zombie army" or "botnet") flood a targeted website or network with overwhelming traffic, making it inaccessible to legitimate users. This is often done by overloading the network with useless data messages or traffic, as in option A. Option B describes antivirus software protection, which is not directly related to DDoS attacks. Option C is not a common or ethical method of cyber defense.

Question 14

Which of the following terms is used to describe a file a computer creates that records successful and unsuccessful access attempts?
A)an access control
B)an attempt log
C)an attack index
D)an audit trail

Accepted Answer

An audit trail is a file that records successful and unsuccessful access attempts, making it the best choice for this question. An access control is a set of mechanisms that regulate who has access to specific resources, and an attempt log and attack index are not common terms in this context.

Question 15

You have encountered a technology that is effective in blocking computer-generated attempts to access a website because it is generally easy for humans to recognize distorted characters. What is this technology?
A)CAPTCHA
B)CERT/CC
C)two-step verification
D)serial authentication

Accepted Answer

CAPTCHA stands for Completely Automated Public Turing test to tell Computers and Humans Apart. It is a technology that presents distorted characters in a challenge-response test to determine whether the user is a human or a computer program attempting to access a website. These distorted characters are usually difficult for computers to detect and read accurately, but easy for humans to identify.

Question 16

The term CAPTCHA is _____________.
A)a private combination of words associated with a user name that allows access to computer resources
B)the average time it takes a computer to discover a password based on the number of characters
C)a digital image used to help decipher a faded or blurry word in digitized news archives
D)a series of distorted characters that a user is required to enter correctly to continue using a website

Accepted Answer

A firewall is a type of hardware and/or software that is designed to protect a network's resources from intrusion. It acts as a barrier between a secure internal network and another network or the internet at large, monitoring and filtering traffic to ensure that it conforms to security policies and that only authorized traffic passes through. Firewalls can be installed on individual computers or at the network level, and can be configured to respond to specific types of traffic or to allow specific types of users access to specific resources.

Question 19
