What is the most common delivery method for viruses?
Correct Answer
A. Email
Explanation
Email is the most common delivery method for viruses. Cybercriminals often use email as a vector to distribute malware by attaching infected files or embedding malicious links within the message. These emails can appear to be from trusted sources, making them particularly dangerous. Once the recipient opens the attachment or clicks the link, the virus can be downloaded and executed on their device, potentially leading to data theft, system damage, or further spread of the malware. While instant messaging, internet downloads, and portable media can also be used to deliver viruses, email remains the most prevalent method due to its widespread use and ease of targeting large numbers of users.

Which of the following would be the best password?
Correct Answer
B. Iw2c^tILV
Explanation
"Iw2c^tILV" is the best password among the options provided because it follows key principles of creating a strong password:
Complexity: It includes a mix of uppercase letters, lowercase letters, numbers, and special characters, making it difficult for attackers to guess or crack through brute force.
Length: It is sufficiently long, which adds another layer of security. Longer passwords are generally harder to crack.
Unpredictability: The password doesn’t include easily guessable words or patterns, unlike "mySecret," "abc123," "keyboard," or "george1234," which are either common, simple, or related to the user (like a name or a common word), making them more vulnerable to attacks.

Your sister sends you an e-mail at work with a screen saver she says you would love. What should you do? (Select all that apply)
Correct Answer
D. Delete the message.
Explanation
This one has four big risks:
1. Some screen savers contain viruses or other malicious programs, so just in general, it's risky to put unknown or unsolicited programs or software on your computer.
2. Also, in some cases just clicking on a malicious link can infect a computer, so unless you are sure a link is safe, don't click on it.
3. Email addresses can be faked, so just because the email says it is from someone you know, you can't be certain of this without checking.
4. Finally, some websites and links look legitimate, but they're really hoaxes designed to steal your information.

The mouse on your computer screen starts to move around on its own and click on things on your desktop. What do you do? (Select all that apply)
Correct Answer
B. Contact the IT Helpdesk immediately.
Explanation
This is definitely suspicious. Immediately report the problem to the IT Help Desk.
Also, since it seems possible that someone is controlling the computer remotely, it is best if you can disconnect the computer from the network until help arrives. If possible, do not turn off the computer.

When receiving an email from an unknown contact that has an attachment, you should:
Correct Answer
B. Delete the email
Explanation
When you receive an email from an unknown contact that contains an attachment, the safest course of action is to delete the email. Opening attachments from unknown sources is a common way that malware, including viruses, ransomware, and spyware, can be delivered to your computer or network. These malicious attachments can cause significant damage, such as stealing personal information, encrypting files for ransom, or spreading to other systems. Forwarding the email, either to your co-workers or your personal email account, is also dangerous because it can spread potential threats to others. Deleting the email immediately helps protect both you and others from the risks associated with unknown attachments.
6.
Which of the following is a proper use of email?
Correct Answer
A. Never email personal information
Explanation
Sending personal information through email is not a proper use because it can potentially compromise the security and privacy of the information. Email is not a secure method of communication, and personal information such as social security numbers, credit card details, or passwords should never be shared through email. It is important to use more secure methods, such as encrypted messaging or secure file sharing, when transmitting personal information.

You receive an e-mail with an attachment from "I.T. Security." The e-mail says that your computer has been infected with a virus and you need to open the attachment and follow the directions to get rid of the virus. What should you do? (Select all that apply)
Correct Answer(s)
D. Delete the message from the unknown source.
E. Contact the IT Help Desk and ask about the email.
ExplanationAttachments can contain viruses and other malicious programs that can infect your computer, so opening or clicking on an unexpected or unknown attachment is very risky.
If you can tell that this is spam, delete the E-mail message. If you are unsure about whether you should open the attachment, contact the IT Help Desk
[email protected] for further instructions. As a general rule, don't open, reply to, or forward suspicious e-mails or attachments

Which of the following is a good way to create a password? (Select all that apply)
Correct Answer(s)
C. A combination of upper and lowercase letters mixed with numbers and symbols
E. Using a password generator
Explanation
A secure password is at least eight characters long.
Does not contain your user name, real name, or company name.
Does not contain a complete word.
Is significantly different from previous passwords.
Contains characters from each of the following four categories:
Uppercase letters
Lowercase letters
Numbers
Symbols

Instant Messaging is safer than regular email.
Correct Answer
B. False
Explanation
While instant messaging (IM) can offer certain security features, it is not inherently safer than regular email. Both instant messaging and email have their own security risks and vulnerabilities. Instant messaging platforms can be susceptible to phishing attacks, malware, and eavesdropping, especially if the platform doesn't use end-to-end encryption or if users click on malicious links or download files from unknown sources.

If a co-worker sends you an email with a link to a website and a subject line that reads "You have to see this...soooo funny" (Select all that apply)
Correct Answer(s)
B. Delete the email
C. Forward the email to your personal email, open it at home and hope that it does not contain a virus
D. Ask Donna to stop it
Explanation
The best action when receiving a suspicious email, like one with a vague subject line and an unexpected link, is to delete it immediately. Opening the link or forwarding the email could spread malware or phishing attacks to others, compromising your security and that of your contacts. It's important to avoid risky behavior, such as opening the email on a personal account or passing it along to others. Deleting the email is the safest way to protect yourself and your network from potential cyber threats.

Who coined the term "Virus"?
Correct Answer
A. Len Adleman
Explanation
Len Adleman is credited with coining the term "Virus." He is an American computer scientist who, along with his colleagues, developed the RSA encryption algorithm. Adleman used the term "Virus" to describe self-replicating computer programs that can infect other programs and disrupt computer systems. His work has been influential in the field of computer security and cryptography.
13.
Which of the following is a type of computer threat?
Correct Answer
C. Dos Attack
Explanation
A DoS (Denial of Service) attack is a type of computer threat where an attacker overwhelms a target system with a flood of illegitimate requests, rendering it unable to respond to legitimate requests. This can lead to a disruption of services, loss of data, and potential financial or reputational damage. Unlike phishing, which involves tricking individuals into revealing sensitive information, and soliciting, which refers to requesting or seeking something, a DoS attack directly targets the availability and functionality of a computer system. Therefore, the correct answer is Dos Attack.

____________________ is a special software designed to detect computer viruses and avoid them from the system.
Correct Answer
D. Antivirus
Explanation
An antivirus is a specialized software that is specifically designed to detect and prevent computer viruses from infecting a system. It scans files and programs, identifies any potential threats, and takes necessary actions to remove or quarantine them. It provides real-time protection by continuously monitoring the system for any suspicious activities or malware attacks. By regularly updating virus definitions, an antivirus ensures that it can effectively detect and neutralize the latest threats. Therefore, an antivirus is an essential tool for maintaining the security and integrity of a computer system.
15.
