What is "Social Engineering" ??

I didn't know the words, "Social Engineering" before today.

So, I reserched about ir.

It is kind of hacking.
To get important private datas such as passwords by illegal way.



For example..

1.Hunting trash box to take memos of clue of someone's personal information or passwords.

2.Calling network site and ask password by pretend to be a user


It was caused by inadequate system of keeping personal information.
So we should be careful about keeping important information.
In japan, there are many social engineering problems, especially at company.
We should keep our important information by ourselves to be safe.
