Tailgating (a.k.a piggybacking)

Tailgating (a.k.a piggybacking)

The act of following someone into a secured area, usually by exploiting someone’s courtesy of “holding the door”. To mitigate against this type of physical intrusion, it should be explicitly stated in the organisation’s security policy that tailgating is not permitted. A thief physically entering your premises can steal unattended computing devices in a matter of seconds (as what happened at Bord Gais headquarters when an intruder stole 4 laptops some which contained customer data). Your IT security awareness training program should create awareness of the tailgating risk along with practical mitigation strategies.
