Fun Cyber Security Quiz

"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.

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.

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.

Using email to share a job opening is considered a proper and professional use, especially when it could benefit others. It supports networking and career opportunities. In contrast, emailing personal information can pose security risks, forwarding humorous content at work may be inappropriate or distracting, and using email to promote personal business can violate workplace policies or seem unprofessional if not done through proper channels.

All of the options listed, namely McAfee, Quick Heal, and Kaspersky, are examples of antivirus programs. Each of these programs is designed to detect, prevent, and remove malicious software or malware from a computer system. They provide real-time protection, regular system scans, and updates to ensure the security of the system. Therefore, the correct answer is "All of the above."

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.

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.

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.

Fred Cohen is known for his work in computer virus defense techniques. He is a computer scientist and is credited with coining the term "computer virus." Cohen conducted groundbreaking research on computer viruses in the 1980s and developed early techniques for detecting and defending against them. His work laid the foundation for modern antivirus software and helped establish the field of computer security.

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.

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.

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.

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 attachments

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

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.
