CompTIA Security+ (SY0-501) — Question 460

A security auditor is testing perimeter security in a building that is protected by badge readers. Which of the following types of attacks would MOST likely gain access?

Answer options

• A. Phishing
• B. Man-in-the-middle
• C. Tailgating
• D. Watering hole
• E. Shoulder surfing

Correct answer: C

Explanation

Tailgating is the most likely attack in this scenario because it involves an unauthorized person following an authorized individual into a secure area, bypassing the badge reader system. Phishing, man-in-the-middle, watering hole, and shoulder surfing do not directly exploit physical access controls like badge readers, making them less relevant in this context.
