CompTIA Security+ Practice Questions
Master the General Security Concepts Domain
Test your knowledge in the General Security Concepts domain with these 5 practice questions. Each question is designed to help you prepare for the CompTIA Security+ certification exam with detailed explanations to reinforce your learning.
Question 1
Which of the following best describes a zero-day vulnerability?
A) A vulnerability that is used by attackers immediately after it is discovered
B) A vulnerability that has been patched by the vendor
C) A vulnerability that is only found in open-source software
D) A vulnerability that has been known for more than a year
Show Answer & Explanation
Correct Answer: A
Explanation: A zero-day vulnerability is one that is exploited by attackers before the vendor has released a patch. It is irrelevant whether the software is open-source, and it is not a patched or longstanding vulnerability.
Question 2
Which of the following is the most effective way to protect against insider threats?
A) Implementing strict password policies
B) Conducting background checks during hiring
C) Deploying a robust access control system
D) Using encryption for sensitive data
Show Answer & Explanation
Correct Answer: C
Explanation: CORRECT: Deploying a robust access control system ensures that employees have access only to the resources necessary for their job, reducing the risk of insider threats. OPTION A: Strict password policies help secure accounts but do not prevent misuse of access by insiders. OPTION B: Background checks can help identify potential risks but do not prevent insider threats after hiring. OPTION C: Encryption protects data from unauthorized access but does not control user access. OPTION D: Access control systems are essential for managing and limiting user permissions effectively.
Question 3
A recent security review reveals that your company's database is vulnerable to SQL injection attacks. What should you do first to address this issue?
A) Sanitize and validate all user inputs on the application.
B) Encrypt the database contents.
C) Increase the strength of database user passwords.
D) Implement a web application firewall (WAF).
Show Answer & Explanation
Correct Answer: A
Explanation: Sanitizing and validating user inputs is the first line of defense against SQL injection, as it prevents malicious inputs from being executed. Encrypting data and strengthening passwords improve security overall but do not prevent SQL injection. A WAF can help but should come after input validation. Generated by AI.
Question 4
What is the primary purpose of a vulnerability assessment?
A) To exploit security weaknesses
B) To identify and evaluate security weaknesses
C) To improve network performance
D) To provide secure remote access
Show Answer & Explanation
Correct Answer: B
Explanation: CORRECT: The primary purpose of a vulnerability assessment is to identify and evaluate security weaknesses in a system. OPTION A: Exploiting weaknesses is not the purpose of a vulnerability assessment. OPTION B: Identifying and evaluating security weaknesses is the correct purpose. OPTION C: Improving network performance is not the purpose of a vulnerability assessment. OPTION D: Providing secure remote access is not the purpose of a vulnerability assessment.
Question 5
A company is implementing a new security policy that requires all employees to use two-factor authentication (2FA) for system access. Which of the following is a primary benefit of this approach?
A) Increased user convenience
B) Reduced password complexity
C) Enhanced security
D) Lower administrative overhead
Show Answer & Explanation
Correct Answer: C
Explanation: CORRECT: Two-factor authentication significantly enhances security by requiring two forms of verification, reducing the risk of unauthorized access. OPTION A: 2FA often decreases convenience due to additional steps. OPTION B: It does not inherently reduce password complexity requirements. OPTION C: Enhanced security is the primary benefit of 2FA. OPTION D: 2FA can increase administrative overhead due to the need for additional management.
