Question 1

Hackers create a botnet by

Accepted Answer

Hackers create a botnet by causing other people's computers to become "zombie" PCs following a master computer. This is typically done through the installation of malware on unsuspecting users' computers or by exploiting vulnerabilities in software or networks. Once a computer is infected, it can be controlled remotely by the hacker and used to carry out various malicious activities as a part of a larger botnet.

Accepted Answer

The intentional defacement or destruction of a Web site is known as cybervandalism. This involves the modification, deletion, or destruction of website content and is often done for political, social, or personal reasons. Spoofing, cyberwarfare, phishing, and pharming are all different types of cyber attacks, but they do not specifically involve the defacement or destruction of a website.

Question 5

A Trojan horse

Accepted Answer

A Trojan horse is a type of malware that appears to be harmless or beneficial, but in fact, performs various malicious activities on the user's computer. It is named after the famous Trojan horse in Greek mythology, which was a large wooden horse used to sneak Greek soldiers into the city of Troy. In the same way, a Trojan horse tricks users into downloading and installing it, while actually performing unauthorized activities, such as stealing data or damaging files.

Question 6

Accepted Answer

Click fraud is a type of online advertising fraud that occurs when someone repeatedly clicks on an online ad with the intention of increasing the advertising costs of the advertiser. In this case, the salesperson is clicking on the online ads of a competitor's, which is a deceptive practice used to drain the competitor's advertising budget and damage their online presence. Phishing, pharming, spoofing, and evil twins are different types of online fraud, but they are not applicable in this scenario.

Question 8

________ is malware that logs and transmits everything a user types.

Accepted Answer

A keylogger is a type of malware that records every keystroke made by a user and can transmit that information back to a hacker or attacker. This can include login credentials, sensitive personal information, and other potentially harmful data. Spyware is a more general term that encompasses a range of malware designed to spy on users, while a Trojan horse is malware that disguises itself as a legitimate program to trick users into running it. Worms and sniffers are different types of malware that do not necessarily focus on collecting user input in the same way that keyloggers do.

Question 9

Large amounts of data stored in electronic form are ________ than the same data in manual form.

Accepted Answer

Large amounts of data stored in electronic form are vulnerable to many more kinds of threats compared to the same data in manual form. These threats include hacking, malware, system crashes, and other cybersecurity risks. This is why businesses need to invest in robust cybersecurity measures to protect their electronic data.

Question 10

Question 13

The communications lines in a client/server environment are specifically vulnerable to

Accepted Answer

The communications lines in a client/server environment can be tapped or intercepted by attackers, which can lead to eavesdropping or data theft. This makes tapping a specific vulnerability that must be addressed through encryption or other security measures. Vandalism and software failure may also be risks, but are not as specific to the client/server environment as tapping is. Malware and errors are risks that are more related to individual computers or devices than the communications lines themselves.

Question 14

Which of the following statements about the Internet security is not true?

Accepted Answer

VoIP is not necessarily more secure than the switched voice network. Both have their security vulnerabilities and depend on the security measures in place.

Question 15

Using numerous computers to inundate and overwhelm the network from numerous launch points is called a(n)________ attack.

Accepted Answer

DDoS stands for Distributed Denial of Service, in which multiple computers (called a botnet) are used to flood a network with traffic, making it unavailable to users. This is different from a regular DoS (Denial of Service) attack, which uses just one computer to flood the network. SQL injection is a type of cyber attack aimed at manipulating an application's backend database, and phishing is a social engineering technique used to trick individuals into revealing sensitive information.

Question 16

________ refers to policies,procedures,and technical measures used to prevent unauthorized access,alteration,theft,or physical damage to information systems.

Accepted Answer

The definition matches the concept of security, which refers to protecting an information system from unauthorized access and misuse. Controls, benchmarking, algorithms, and identity management are all related to security, but not the primary concept of preventing unauthorized access, alteration, theft, or physical damage.

Question 17

Which of the following is not an example of a computer used as a target of crime?

Accepted Answer

The answer of Which of the following is not an...

Question 18

Electronic data are more susceptible to destruction,fraud,error,and misuse because information systems concentrate data in computer files that

Accepted Answer

Electronic data, when stored in computer files, can be easily accessed and compromised by anyone who has access to the same network. This makes it highly susceptible to misuse, fraud, and destruction. It is therefore important to ensure that proper security measures are in place to protect electronic data from unauthorized access.

Question 19

________ is malware that hijacks a user's computer and demands payment in return for giving back access.

Accepted Answer

Ransomware is the malware that hijacks a user's computer and demands payment in return for giving back access. Trojan horse, spyware, virus, and evil twin are different types of malware with different behaviors and purposes.

Question 20

Client software in a client/server environment is specifically vulnerable to

Accepted Answer

Client software is specifically vulnerable to unauthorized access as it often involves user authentication and data exchange, making it a target for attackers seeking to gain unauthorized entry.
