What is "Social Enginerring"?

Social Engineering

It also can be called social hacking, or social cracking.
Social engineering is to get ID or password by using any methods in order to enter network system illegally. Due to lack of identification, or incompleteness of rules in organization, it causes a leak of secret information. It is not so difficult to do because listening stealthily, looking furtively can be it. Also, to ask information of parents from child who get phone call is one of social engineering.
There are some solutions. Solution for organization is to make an identification which is difficult to forge, or reminding the handling of important information. To tell some company’s information on the phone is the most unreasonable.
In a house, you should teach your son/daughter not to get phone call, and using shredder is also good for keeping important information at home.
