Hacking is the practice of illegally gaining access to a computer or network. The term hacking is also used to describe the art of opening up a piece of electronics and modifying it. Some people argue that illegal hackers should be called crackers. This opinion is not widely held. There are white hat hackers that legally test corporate security. Many hackers justify their hacking by saying that information should be free or that they are finding holes, thus strengthen computer security by bringing these holes to the attention of system administrators. And since this is not the forum for debate I will not comment on those justifications.
Hackers with concent are called ethical hackers and they are encharged with keeping the virus threat up to a minimal level.
