Tailgating

   

In tailgaiting an attacker can gain access to a restricted, locked down area by following someone into the restricted area who does have access and acting like they belong.  The first video showed the target allowed the user full access to the restricted room.

But the second version showed that he clearly stopped him from access.

Why it Works


Again, tailgating works because people are polite and will hold doors open for others as they enter a building. It's actually considered rude not to hold the door. Combating the Tailgater is also easy as Lloyd the Contractor showed. Simply "remind" the intruder of the security protocol and close the door behind you. No need to be rude, just firm.
