Cyber law governs the legal issues of cyberspace and that"cyberspace"is not restricted to the internet,but includes computers and computer networks,the Internet,data,software etc.The information technology is a double edge sword,which can be used for destructive as well as constructive work.Thus the fate of many ventures depends upon the benign or vice intentions,as the case may be,the person dealing with and using the technology.A malicious intention forwarded in the form of hacking,data theft,virus attack,etc.can bring only destructive results.These methods however may also be used for checking the authenticity, safety and security of ones technological device,which has been primarily relied upon and trusted for providing the security to a particular organisation.For instance the creater of the"Sasser Worm"has been hired as a"Security Software Programmer"by a German firm,so that he can make firewalls,which will stop suspected files from entering computer systems.This exercise of hiring those persons who are responsible for causing havoc and nuisance is the recognition of the growing and inevitable need of"Self protection",which is recognized in all the countries of the world.
