Following an authorized person through a door or other security check point without showing proper identification or defeating a security mechanism is known as which of the following?

Hacking refers to exploiting technical vulnerabilities in systems or networks, not physically bypassing access controls by following someone.

Emulating means mimicking the behavior of a system or device (such as hardware emulation) and has no relation to physical access bypass techniques.

Partitioning refers to dividing storage media or network segments into logical sections and is entirely unrelated to physical security breaches.

Tailgating (also called piggybacking) specifically describes the act of bypassing physical security controls by following an authorized person through a door or checkpoint without presenting credentials or defeating the security mechanism independently - which is exactly the scenario described.
