Understanding Tailgating as a Security Threat

What is Tailgating?

Tailgating is an unauthorized entry of an individual into a controlled area by following an authorized person. Tailgating is a security threat that can lead to physical or data theft. It is also known as piggybacking or social engineering, and it involves an unauthorized person gaining access to a restricted area by following an authorized person through an access point like a door, gate, or turnstile.

What are the different types of Tailgating?

There are two different types of tailgating:

Active tailgating: This type involves a person physically present who follows an authorized individual to gain access to a restricted area. An example is following someone into a secure area.

Passive tailgating: This type involves the unauthorized individual waiting until the authorized person enters the area and then sneaking in before the door closes. An example is using an open door to enter a restricted area.
