What is the information security and useful?

What is security information Imagine with me that among the people there must be security "national security" and this security is the welfare of the citizens, but this is in fact there is something called virtual reality and parents enter the millions of people every day and you are among them.

But if there were thefts in fact must be thefts virtual reality and my brother brother was created a field called information security.

 Now in reality or in our daily life how to catch a person only by his home address and on the Internet there is an address called ip and every person has the address and role of religion people working in security My information is protecting the privacy.

There are companies in the Internet as is the case in fact companies in reality is being robbed with weapons and power, but in the Internet only through a little experience is stolen and now it is no longer thefts in fact because the companies affiliated Dahbo to the Internet and this will be part of the attempts to steal by hackers to him Information security is an area that is required globally both at this time and in the future.

And the example is a ransom virus, the world's most terrifying if the security did not interfere with my information to stop the spread !! .
