(Continuation from yesterday)

If our systems are hijacked by a outside cyber attack, our business is going to stop absolutely. It is awful if I think about the total cost of missing materials and program.

In the worst case, a customer's information will leaked out. We should care of our customer's damage, more than our pride. Of course, the customer will never get a job to us again.

And once the data is leaked out on the net, we can not either collect or erase it.

Now all the huge systems are virtualized, and we can carry it in a USB memory completely.

Even the systems which are separated from the Internet completely are invaded, destroyed. and whose information is pulled out.

Moreover, the most fearful object is a person who do not feel such "fear" for IT engineers.

Sometimes the person is a member of family.

"Losing USB memory" is a phrase that makes me go go pale, however,

it is absolutely difficult to make this family understand this horror, like,

"Make unskilled indigenous people understand the concept of money"
