CompTIA Security+ (SY0-501) — Question 681

An organization has air gapped a critical system.
Which of the following BEST describes the type of attacks that are prevented by this security measure?

Answer options

• A. Attacks from another local network segment
• B. Attacks exploiting USB drives and removable media
• C. Attacks that spy on leaked emanations or signals
• D. Attacks that involve physical intrusion or theft

Correct answer: A

Explanation

Air gapping effectively isolates a critical system from other network segments, thus preventing attacks that originate from those segments. While it may reduce the risk of USB drive exploitation and physical intrusion, it does not directly mitigate threats from removable media or signals, making option A the best choice.
