CompTIA Security+ (SY0-501) — Question 212
Which of the following is the BEST choice for a security control that represents a preventive and corrective logical control at the same time?
Answer options
- A. Security awareness training
- B. Antivirus
- C. Firewalls
- D. Intrusion detection system
Correct answer: B
Explanation
Antivirus software is designed to prevent malware infections and can also correct issues by removing malware once detected, making it the best choice for a control that serves both purposes. In contrast, security awareness training focuses on user behavior, firewalls primarily act as a barrier, and intrusion detection systems mainly alert on breaches without correcting them.
