Multiple choice

What is the term used for a type of cyberattack in which an attacker gains unauthorized access to a computer system by exploiting a vulnerability in the system's software?

  1. Phishing

  2. Malware

  3. Brute-force attack

  4. Zero-day attack
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A zero-day attack is a cyberattack that exploits a previously unknown vulnerability in a computer system's software. This type of attack is particularly dangerous because there is no known defense against it until a patch is released to fix the vulnerability.

Multiple choice

Which of the following is a common defense mechanism used to protect against unauthorized access to a computer system?

  1. Firewall

  2. Antivirus software

  3. Intrusion detection system

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Firewalls, antivirus software, and intrusion detection systems are all common defense mechanisms used to protect against unauthorized access to a computer system. Firewalls block unauthorized traffic from entering or leaving a network, antivirus software scans for and removes malicious software, and intrusion detection systems monitor network traffic for suspicious activity.

Multiple choice

What is the term used for a type of cyberattack in which an attacker sends a large number of requests to a website or online service in order to overwhelm it and make it unavailable to legitimate users?

  1. Denial-of-service attack

  2. Phishing

  3. Malware

  4. Brute-force attack
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A denial-of-service attack is a cyberattack in which an attacker sends a large number of requests to a website or online service in order to overwhelm it and make it unavailable to legitimate users. This type of attack can be used to disrupt online businesses, government services, or other critical infrastructure.

Multiple choice

Which of the following is an example of a social engineering attack?

  1. Phishing

  2. Malware

  3. Brute-force attack

  4. Zero-day attack
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Phishing is a type of social engineering attack in which an attacker sends a fraudulent email or text message that appears to be from a legitimate source in order to trick the recipient into giving up sensitive information, such as their password or credit card number.

Multiple choice

What is the term used for a type of cyberattack in which an attacker gains unauthorized access to a computer system by guessing the password?

  1. Phishing

  2. Malware

  3. Brute-force attack

  4. Zero-day attack
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A brute-force attack is a type of cyberattack in which an attacker gains unauthorized access to a computer system by guessing the password. This type of attack is often used to crack passwords for online accounts or to gain access to encrypted files.

Multiple choice

What is the term used for a type of cyberattack in which an attacker gains unauthorized access to a computer system by exploiting a vulnerability in the system's hardware?

  1. Phishing

  2. Malware

  3. Side-channel attack

  4. Zero-day attack
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A side-channel attack is a type of cyberattack in which an attacker gains unauthorized access to a computer system by exploiting a vulnerability in the system's hardware. This type of attack can be used to extract sensitive information, such as cryptographic keys, from a computer system without having to guess the password.

Multiple choice

Which of the following is a common defense mechanism used to protect against malware?

  1. Firewall

  2. Antivirus software

  3. Intrusion detection system

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Antivirus software is a common defense mechanism used to protect against malware. Antivirus software scans files for malicious code and removes it if it is found.

Multiple choice

What is the term used for a type of cyberattack in which an attacker gains unauthorized access to a computer system by exploiting a vulnerability in the system's software?

  1. Phishing

  2. Malware

  3. Buffer overflow attack

  4. Zero-day attack
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A buffer overflow attack is a type of cyberattack in which an attacker gains unauthorized access to a computer system by exploiting a vulnerability in the system's software. This type of attack can be used to execute arbitrary code on the computer system.

Multiple choice

What is the term used for a type of cyberattack in which an attacker gains unauthorized access to a computer system by exploiting a vulnerability in the system's network configuration?

  1. Phishing

  2. Malware

  3. Man-in-the-middle attack

  4. Zero-day attack
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A man-in-the-middle attack is a type of cyberattack in which an attacker gains unauthorized access to a computer system by exploiting a vulnerability in the system's network configuration. This type of attack can be used to intercept and modify data that is being transmitted between two parties.

Multiple choice

Which of the following is a common defense mechanism used to protect against man-in-the-middle attacks?

  1. Firewall

  2. Antivirus software

  3. Intrusion detection system

  4. Virtual private network (VPN)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A virtual private network (VPN) is a common defense mechanism used to protect against man-in-the-middle attacks. A VPN encrypts data that is being transmitted between two parties, making it difficult for an attacker to intercept and modify the data.

Multiple choice

  1. Phishing

  2. Malware

  3. Kernel exploit

  4. Zero-day attack
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A kernel exploit is a type of cyberattack in which an attacker gains unauthorized access to a computer system by exploiting a vulnerability in the system's operating system. This type of attack can be used to execute arbitrary code on the computer system.

Multiple choice

Which of the following is a common defense mechanism used to protect against kernel exploits?

  1. Firewall

  2. Antivirus software

  3. Intrusion detection system

  4. Patch management
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Patch management is a common defense mechanism used to protect against kernel exploits. Patch management involves regularly updating the operating system and software on a computer system with the latest security patches. This helps to fix vulnerabilities that could be exploited by attackers.
