Cyber Security Questions and Answers
- 1.
What is the most common delivery method for viruses?
- A.
Email
- B.
Instant Message
- C.
Internet download
- D.
Portable media
Correct Answer
A. EmailExplanation
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.Rate this question:

Which of the following would be the best password?
- A.
MySecret
- B.
Iw2c^tILV
- C.
Abc123
- D.
Keyboard
- E.
George1234
Correct Answer
B. Iw2c^tILVExplanation
"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.Rate this question:

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)
- A.
Download it onto your computer, since it's from a trusted source.
- B.
Forward the message to other friends to share it.
- C.
Call IT and ask them to help install it for you
- D.
Delete the message.
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.Rate this question:

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)
- A.
Call your co-workers over so they can see.
- B.
Contact the IT Helpdesk immediately.
- C.
Unplug your mouse.
- D.
Turn your computer off.
- E.
Run anti-virus.
- F.
All of the above.
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.Rate this question:

When receiving an email from an unknown contact that has an attachment, you should:
- A.
Open the attachment to view its contents
- B.
Delete the email
- C.
Forward the email to your co-workers to allow them to open the attachment first
- D.
Forward the email to your personal email account so you can open it at home
Correct Answer
B. Delete the emailExplanation
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.Rate this question:

Which of the following is a proper use of email?
- A.
Never email personal information
- B.
Send out pricelists for your home-based business products
- C.
Forward inspirational and humorous emails to your co-workers to brighten their day
- D.
Send an email to all your friends and co-workers to advertise a job opening in your area
Correct Answer
A. Never email personal informationExplanation
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.Rate this question:

Correct Answer(s)
D. Delete the message from the unknown source.
E. Contact the IT Help Desk and ask about the email.Explanation
Attachments 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 attachmentsRate this question:

Instant Messaging is safer than regular email.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
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.Rate this question:

Which of the following techniques is most effective in preventing Man-in-the-Middle (MitM) attacks during the initial key exchange process in a TLS handshake?
- A.
Using a Pre-Shared Key (PSK) for the initial exchange
- B.
Implementing Perfect Forward Secrecy (PFS) with Diffie-Hellman key exchange
- C.
Relying on static RSA key exchange
- D.
Employing digital certificates signed by a trusted Certificate Authority (CA)
Correct Answer
B. Implementing Perfect Forward Secrecy (PFS) with Diffie-Hellman key exchangeExplanation
Option B is correct because Perfect Forward Secrecy (PFS) with Diffie-Hellman ensures that each session’s key is unique and not derived from the server's private key, protecting against Man-in-the-Middle (MitM) attacks even if the server’s key is compromised. While digital certificates (Option D) establish trust, they don't prevent MitM during key exchange. Static RSA (Option C) and Pre-Shared Keys (Option A) offer weaker protection compared to PFS.Rate this question:

Which of the following is a type of computer threat?
- A.
Phishing
- B.
Soliciting
- C.
Dos Attack
- D.
None of the above
Correct Answer
C. Dos AttackExplanation
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.Rate this question:
