Question

which social engineering technique do mantraps defend against?
spear phishing
whaling
tailgating
impersonation
dumpster diving

Explanation:

Mantraps are physical security devices that prevent unauthorized entry by only allowing one person to pass at a time, which specifically defends against tailgating (where an unauthorized person follows an authorized one through a secured door). Spear phishing, whaling, impersonation, and dumpster diving are social engineering techniques that mantraps do not directly defend against as they involve different methods (e.g., phishing via emails, pretending to be someone, or searching through trash).

Answer:

C. Tailgating
