Social Engineering

I searched about "Social Engineering" on the Internet. It is like a hacker in their working. Actually, I read about hacker in textbook of EAP. However, I found one big different point between hacker and social engineering. Social engineering is cleverer than hacker to deceive people, so naturally by using phone or answering service. It means that social engineering is to pretend other parson. On the other hand, hacker is so good at using computer, skilfully. In addition, they have same purpose that is to get personal information in order to commit fraud, get money, break the system or network and so on. In the case of social engineering, they have two types of attacks that are the physical and psychological. It is to pretending and using great skill of computer. After all, it may be just like playing games for them.
