Jimmy is standing outside a secure entrance to a facility. He is pretending to have a tense conversation on his cell phone as an authorized employee badges in.
Jimmy, while still on the phone, grabs the door as it begins to close.
What just happened?
In this scenario, Jimmy is taking advantage of the authorized employee who is badging into the facility to gain entry without using his own credentials. This behavior is known as piggybacking, where an unauthorized person follows an authorized person into a secure area. The other options like masquerading, phishing, and whaling do not describe this physical security breach.
And what about Tailgating is the right answer to this question.
It is the right answer, however piggybacking is the only option that is correct as well
Piggybacking is when you enetring a organization with permition of another authorized/legitimate person, tailgating is when you do this without knowledge or without asking authorized/legitimate person. There is not better choice then piggybacking so this is a best answer
