Impersonation

Pretending to be another person or role, such as an executive, technician or vendor, to gain trust or access.

Definition

Impersonation is used in phishing, vishing and physical intrusion, where attackers wear uniforms or carry fake badges. It leverages the authority and trust principles. Identity verification and visitor management controls counter it.

Example

An intruder in a courier uniform walks into a server room claiming to deliver equipment.

Exam tip

Impersonation is a component of many attacks; look for "posing as" in the question.
