Question 2

Smartphones share the same security weaknesses as other Internet devices and are vulnerable to malicious software and penetration from outsiders.

Accepted Answer

Smartphones are susceptible to the same security weaknesses as other Internet-connected devices such as laptops, tablets, and desktops. They can be compromised by various cyber-attacks, including phishing, malware, and other forms of hacking. Therefore, due to the security risks, it is necessary to protect smartphones with adequate security measures such as passwords, VPNs, and antivirus software.

Question 3

FLQ injection attacks are the largest malware threat,their attacks take advantage of vulnerabilities in poorly coded Web application software to introduce malicious program code into a company's systems and networks.

Accepted Answer

The statement describes SQL injection attacks, not FLQ injection attacks. SQL injection is a common type of attack that exploits vulnerabilities in web applications.

Question 4

SSL is a protocol used to establish a secure connection between two computers.

Accepted Answer

SSL (Secure Sockets Layer) is a protocol used to establish a secure connection between two computers. It ensures that any data transmitted between the two computers is encrypted and cannot be intercepted by unauthorized third parties.

Question 5

High-availability computing is also referred to as fault tolerance.

Accepted Answer

The answer of High-availability computing is also referred to as...

Question 6

Fault-tolerant computers contain redundant hardware,software,and power supply components.

Accepted Answer

Fault-tolerant computers are designed to continue functioning even in the event of hardware or software failure, and this is achieved through the use of redundant components such as processors, memory modules, hard drives, and power supplies. This redundancy ensures that if one component fails, the system can automatically switch to a back-up component without overall system failure.

Question 7

The Cornflicker worm was first identified in January 2007.It spreads via e-mail spam with a fake attachment.Infected up to 10 million computers,causing them to join its zombie network of computers engaged in criminal activity.

Accepted Answer

The statement is incorrect. The worm is fictitious and does not exist in real life.

Question 8

Businesses must protect only their own information assets but not those of customers,employees,and business partners.

Accepted Answer

Businesses have a responsibility to protect not only their own information assets but also those of their customers, employees, and business partners to whom they may have access. This is crucial for maintaining the security and trust necessary for successful business relationships.

Question 9

Betty downloaded a peer to peer file sharing program.She is worried that it might have come with spyware attached to it.She had a friend who had a spyware problem where all of her keystrokes were stolen which included her bank passwords.Betty's friend was a victim of ________.
A)spoofing
B)keyloggers
C)a Trojan horse
D)worms

Accepted Answer

Keyloggers are a type of spyware that record all keystrokes made on a computer, including passwords and other sensitive information. Spoofing involves disguising oneself as a trusted source to gain access to sensitive information, while Trojan horses and worms are types of malware that can cause damage to a computer or network. Therefore, keyloggers are the most likely choice here given that Betty's friend had her keystrokes stolen.

Question 10

Helen downloaded a greeting card program from the internet.She was surprised that it really didn't do what it was supposed to do.What the program did was send nasty,profane e-mails to all the people in her contact list.Helen is the victim of ________.
A)spoofing
B)keyloggers
C)a Trojan horse
D)worms

Accepted Answer

Helen is a victim of a Trojan horse, which is a type of malware that disguises itself as a harmless program but actually carries out harmful actions. Spoofing involves disguising oneself as a trusted source to gain unauthorized access, keyloggers record keystrokes to steal sensitive information, and worms replicate themselves to spread through networks.

Question 11

________ is/are methods,policies,and organizational procedures ensuring the safety of the organization's assets,the accuracy and reliability of its records,and operational adherence to management standards.
A)"Security"
B)"Controls"
C)"Benchmarking"
D)"Algorithms"

Accepted Answer

Controls are methods, policies, and organizational procedures put in place to ensure the safety of the organization's assets, accuracy and reliability of its records, and operational adherence to management standards. Security refers to the protection of an organization's assets whereas benchmarking is a process of comparing an organization's processes with industry standards or best practices. Algorithms refer to a set of rules or steps used to solve a problem or perform a task.

Question 12

Public key encryption uses two keys.

Accepted Answer

Public key encryption uses two keys - a public key and a private key. The public key is used to encrypt data, while the private key is used for decryption.

Question 13

The Conficker worm uses flaws in Windows software to take over machines and link them into a virtual computer that can be commanded remotely.

Accepted Answer

This statement is true. The Conficker worm is a type of malware that exploits vulnerabilities in Windows operating systems to create a network of infected machines that can be controlled by a remote attacker. The worm first appeared in 2008 and has since caused widespread damage and disruption to computer systems around the world.

Question 14

NAT conceals the IP addresses of the organization's internal host computers to deter sniffer programs.

Accepted Answer

NAT (Network Address Translation) changes the source IP address of outgoing packets to a different IP address before sending them to the internet, thus hiding the internal IP addresses behind the public IP address of the network gateway. This can deter sniffer programs from identifying and targeting specific computers on the internal network.

Question 15

The Sasser.ftp worm Word macro script mailed an infected Word file to the first 50 entries in a user's Microsoft Outlook address book.Infected 15 to 29 percent of all business PCs,causing $300 million to $600 million in damage.

Accepted Answer

The Sasser.ftp worm did not use Word macro script and did not infect through email. It spread through network exploits and caused an estimated $18 billion in damages.

Question 16

Domestic or offshore partnering with another company adds to system vulnerability if valuable information resides on networks and computers outside the organization's control.

Accepted Answer

Domestic or offshore partnering involves sharing sensitive information with another company, and if that information is stored on networks and computers that are not under the organization's control, it increases the risk of a security breach or data loss. Therefore, it adds to system vulnerability.

Question 17

Many Wi-Fi networks can be penetrated easily by intruders using sniffer programs to obtain an address to access the resources of a network without authorization.

Accepted Answer

Wi-Fi networks using WEP or WPA encryption can be easily penetrated by intruders using sniffer programs to obtain an address and access the resources of a network without authorization. It is important to use strong encryption and secure passwords to protect Wi-Fi networks from unauthorized access.

Question 18

Popular IM applications for consumers do not use a secure layer for text messages,so they can be intercepted and read by outsiders during transmission over the public Internet.

Accepted Answer

Popular IM applications such as WhatsApp, Facebook Messenger, and Snapchat do not use end-to-end encryption for text messages, which means they can be intercepted and read by outsiders during transmission over the public Internet.

Question 19

A)spoofing
B)keyloggers
C)a Trojan horse
D)worms

Accepted Answer

John was almost a victim of spoofing, which is a type of cyber attack where an attacker creates a fake website or email that looks like a legitimate one in order to trick the victim into giving away their personal information, such as login credentials or credit card details.

Question 20

The Melissa worm affected millions of computers worldwide,disrupting British Airways flight check-ins,operations of British Coast Guard stations,Hong Kong hospitals,Taiwan post office branches,and Australia's Westpac Bank.
