In plain English

Tailgating is one of the simplest physical security breaches. An attacker waits near a secured door and, when an authorised person badges in, follows them through before the door closes — relying on social courtesy and the reluctance to challenge strangers. Physical security awareness training teaches staff to politely challenge anyone without a visible badge.
