Social Engineering

The term "Social Engineering" means that a person secretly get the private information to come in the secured zone on the computer using some illegal techniques. For example, workers in a company need to be careful the phone call asking for an ID number or password because the illegal people try to get it secretly by pretending someone in the company. Also, these people try to find these private information from the trash box. In the house field, they might trick children or elderly people on the phone. These are all called "Social engineering" and they are completely to be guilty.
To deal with these problems, we can try several ways; making a certification that is difficult to be forged, using a shredder for used information paper, avoiding a phone call from a telephone booth, a call from an unnoticed number, or any other suspicious numbers.
