Accepted Answer

Email spoofing is commonly used in both virus hoaxes and spam.

Question 2

Encryption is one safeguard against information theft.

Accepted Answer

Encryption is the process of converting sensitive data into a coded language that cannot be easily understood by unauthorized parties, thus protecting it from theft.

Question 3

Unusually high drive activity or a slower than normal Internet activity are signs that your computer or mobile device may be a zombie.

Accepted Answer

Unusually high drive activity or slow Internet activity can indicate that a computer or mobile device has been infected with malware and is being controlled remotely by a hacker without the user's knowledge, making it a zombie device.

Question 4

User IDs are also called user names, log on names, or sign in names.

Accepted Answer

User IDs can be referred to by different names including user names, log on names, or sign in names.

Question 5

Viruses, worms, and trojan horses replicate themselves to other computers or devices.

Accepted Answer

Viruses and worms can replicate themselves to other computers or devices, but trojan horses do not replicate themselves; they act as a backdoor for malicious users to access the system.

Question 6

To protect files on your device's hard drive from hackers, turn on file and printer sharing.

Accepted Answer

Turning on file and printer sharing actually increases the vulnerability of your device to hacking attempts. It is important to keep file sharing disabled and use other security measures such as strong passwords and firewalls to protect your files.

Question 7

Software used to fight cybercriminals is called crimeware.

Accepted Answer

Crimeware refers to software designed specifically for committing crimes, particularly financial fraud. Software used to fight cybercriminals is usually referred to as cybersecurity software or anti-malware software.

Question 8

With a credit card purchase, when users sign their name on a signature capture pad using a stylus, the retailer uses a signature verification system to authenticate the user.

Accepted Answer

Retailers typically do not use a signature verification system to authenticate the user for each transaction. Instead, the signature is more often used for record-keeping purposes and may only be checked if a transaction is disputed.

Question 9

Employers can use firewalls to restrict employees' access to sensitive data.

Accepted Answer

Firewalls can block access to certain websites or applications, preventing employees from accessing sensitive data that could be harmful to the company if it falls into the wrong hands.

Question 10

Piracy is the most common form of software theft.

Accepted Answer

According to various reports and studies, piracy remains the most prevalent form of software theft, especially in countries with weak copyright laws and enforcement mechanisms.

Question 11

Cyberterrorism and cyberwarfare usually require a team of highly skilled individuals, millions of dollars, and several years of planning.

Accepted Answer

Cyberterrorism and cyberwarfare are complex and sophisticated operations that typically require a group of experienced and skilled hackers, significant financial and technological resources, and a significant amount of planning and preparation to execute successfully. These attacks can have significant consequences, ranging from financial losses to national security threats, which is why they are taken seriously by governments and businesses around the world.

Question 12

Two users can have the same email address.

Accepted Answer

Email addresses are unique identifiers for users, meaning that two users cannot share the same email address for account registration or identification purposes.

Question 13

Security experts recommend using different user names and passwords for every account.

Accepted Answer

Using different user names and passwords for every account increases the security of each account and reduces the risk of a security breach affecting multiple accounts.

Question 14

Public key encryption is also called asymmetric key encryption.

Accepted Answer

Public key encryption and asymmetric key encryption refer to the same concept. They use a pair of mathematically related keys for encryption and decryption, where one key is kept private (the private key) and the other is shared publicly (the public key).

Question 15

The website for CERT/CC provides information about Internet security breaches.

Accepted Answer

CERT/CC stands for Computer Emergency Response Team/Coordination Center and is a well-known organization that provides information on Internet security breaches and vulnerabilities. They are operated by the Software Engineering Institute at Carnegie Mellon University.

Question 16

Intentionally erasing software is not an example of software theft.

Accepted Answer

Intentionally erasing software can be considered an example of software theft if it deprives the rightful owner or licensee of their legitimate access to the software or its functionalities.

Question 17

A rootkit can be a backdoor.

Accepted Answer

A rootkit is a type of software that is installed on a computer system to allow attackers to access it without being detected. One of the ways in which it can achieve this is by creating a backdoor, which provides a way for attackers to bypass security measures and gain unauthorized access to the system.

Question 18

A hand geometry system measures the size and shape of a person's hand.

Accepted Answer

Hand geometry systems use sensors to measure the shape and size of a person's hand for identification purposes.

Question 19

Passphrases are less secure than passwords.

Accepted Answer

Passphrases are generally longer and more complex than traditional passwords, making them more difficult to crack. Furthermore, they are typically easier for users to remember and less likely to be written down or shared. Therefore, passphrases are generally considered to be more secure than passwords.

Question 20

If your computer's operating system provides a personal firewall, you do not need to disable it if you are using a third-party firewall.

Accepted Answer

Having both a personal firewall provided by your operating system and a third-party firewall active at the same time can lead to conflicts and decreased system performance. It's generally recommended to use one firewall solution to avoid such issues.
