Which of the following is NOT a common type of software vulnerability?

  1. Buffer overflow

  2. SQL injection

  3. Cross-site scripting (XSS)

  4. Denial of service (DoS)


Correct Option: D
Explanation:

DoS attacks are not vulnerabilities in the software itself, but rather attacks that aim to disrupt the availability of the service.

What is the primary cause of buffer overflow vulnerabilities?

  1. Insufficient input validation

  2. Improper memory management

  3. Lack of encryption

  4. Weak authentication mechanisms


Correct Option: B
Explanation:

Buffer overflow vulnerabilities occur when a program writes data beyond the allocated memory buffer, overwriting adjacent memory locations.

Which of the following is a common technique used to mitigate SQL injection vulnerabilities?

  1. Input validation

  2. Use of prepared statements

  3. Escaping special characters

  4. All of the above


Correct Option: D
Explanation:

Input validation, use of prepared statements, and escaping special characters are all effective techniques to prevent SQL injection attacks.

What is the primary goal of cross-site scripting (XSS) attacks?

  1. Stealing sensitive information

  2. Disrupting the availability of a service

  3. Executing malicious code on the victim's computer

  4. All of the above


Correct Option: C
Explanation:

XSS attacks aim to inject malicious scripts into a web application, allowing the attacker to execute arbitrary code on the victim's computer.

Which of the following is a common defense mechanism against cross-site request forgery (CSRF) attacks?

  1. Use of anti-CSRF tokens

  2. Implementing same-origin policy

  3. Enforcing strict access control

  4. All of the above


Correct Option: D
Explanation:

Using anti-CSRF tokens, implementing same-origin policy, and enforcing strict access control are all effective measures to prevent CSRF attacks.

What is the primary purpose of penetration testing?

  1. Identifying vulnerabilities in a software system

  2. Exploiting vulnerabilities to gain unauthorized access

  3. Mitigating vulnerabilities by applying security patches

  4. Monitoring the security of a system over time


Correct Option: A
Explanation:

Penetration testing aims to identify vulnerabilities in a software system by simulating real-world attacks.

Which of the following is a common type of security misconfiguration vulnerability?

  1. Default passwords

  2. Unnecessary privileges

  3. Lack of encryption

  4. All of the above


Correct Option: D
Explanation:

Default passwords, unnecessary privileges, and lack of encryption are all examples of security misconfiguration vulnerabilities.

What is the primary goal of a security audit?

  1. Identifying vulnerabilities in a software system

  2. Exploiting vulnerabilities to gain unauthorized access

  3. Mitigating vulnerabilities by applying security patches

  4. Assessing the overall security posture of an organization


Correct Option: D
Explanation:

A security audit aims to assess the overall security posture of an organization, including its policies, procedures, and technical controls.

Which of the following is a common type of social engineering attack?

  1. Phishing

  2. Spear phishing

  3. Vishing

  4. All of the above


Correct Option: D
Explanation:

Phishing, spear phishing, and vishing are all types of social engineering attacks that aim to trick individuals into divulging sensitive information or taking actions that compromise security.

What is the primary purpose of a firewall?

  1. Preventing unauthorized access to a network

  2. Detecting and blocking malicious traffic

  3. Monitoring network traffic for suspicious activity

  4. All of the above


Correct Option: D
Explanation:

A firewall serves to prevent unauthorized access to a network, detect and block malicious traffic, and monitor network traffic for suspicious activity.

Which of the following is a common type of network security vulnerability?

  1. Man-in-the-middle (MITM) attacks

  2. Denial of service (DoS) attacks

  3. Distributed denial of service (DDoS) attacks

  4. All of the above


Correct Option: D
Explanation:

Man-in-the-middle (MITM) attacks, denial of service (DoS) attacks, and distributed denial of service (DDoS) attacks are all common types of network security vulnerabilities.

What is the primary goal of a vulnerability assessment?

  1. Identifying vulnerabilities in a software system

  2. Exploiting vulnerabilities to gain unauthorized access

  3. Mitigating vulnerabilities by applying security patches

  4. Assessing the overall security posture of an organization


Correct Option: A
Explanation:

A vulnerability assessment aims to identify vulnerabilities in a software system by analyzing its code, configuration, and network connectivity.

Which of the following is a common type of web application security vulnerability?

  1. SQL injection

  2. Cross-site scripting (XSS)

  3. Cross-site request forgery (CSRF)

  4. All of the above


Correct Option: D
Explanation:

SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF) are all common types of web application security vulnerabilities.

What is the primary purpose of a security patch?

  1. Fixing vulnerabilities in a software system

  2. Exploiting vulnerabilities to gain unauthorized access

  3. Mitigating vulnerabilities by applying security patches

  4. Assessing the overall security posture of an organization


Correct Option: A
Explanation:

A security patch is a software update that fixes vulnerabilities in a software system.

Which of the following is a common type of mobile security vulnerability?

  1. Malware

  2. Phishing

  3. Man-in-the-middle (MITM) attacks

  4. All of the above


Correct Option: D
Explanation:

Malware, phishing, and man-in-the-middle (MITM) attacks are all common types of mobile security vulnerabilities.
