As fast as security grew, the hacking world grew faster. There are two ways of looking at the issue of cyber security. One is that the companies that provide cloud computing do that and only that so these companies will be extremely well secured with the latest in cutting edge encryption technology.

II. WHAT IS CYBER SECURITY ?

Cyber warfare attacks are primarily executed by hackers who are well-trained in use of benefit the quality of details computer networks, and operate under the favourable and support of nation-states. Rather than closing a target?s key networks, a cyber-warfare attack may forced to put into a situation into networks to compromise valuable data, degrade communications, impair such infrastructural services as transportation and medical services, or interrupt commerce. Cyber spionage It is the practice of using information technology to obtain secret information without permission from its owners or holders.
