Explanation:
Tailgating is the term used for someone being so close to you when you enter a building that they are able to
come in right behind you without needing to use a key, a card, or any other security device. Many social
engineering intruders needing physical access to a site will use this method of gaining entry. Educate users to
beware of this and other social engineering ploys and prevent them from happening.
