What Is "Social Engineering"?

Social engineering is a technique to get people’s important private information; for example, passwords for entering some networks, which relate to the security. People who do social engineering get the information by listening to the information secretly, looking victim’s act of typing password from the back of the victim. Moreover, they try to find some private information that would be the key of password from documents which are thrown away in an office. In addition, there is a way to deceive people and enter the network. People who do social engineering pretend to be a customer or user of the network, and they call the manager to change the password. Then, they ask for the new password. All in all, social engineering takes advantage of people’s unawareness of protecting their private information.

I did not know this term before I researched it. However, now I could understand the meaning. At the same time, I realized that I should be more careful about protecting my private information.
