computer security

This article is about computer security hackers. For other types of computer hackers, see Hacker (computing). For other uses, see Hacker.
In common usage, a hacker is a person who breaks into computers, usually by gaining access to administrative controls.[1] The subculture that has evolved around hackers is often referred to as the computer underground. Proponents claim to be motivated by artistic and political ends, and are often unconcerned about the use of illegal means to achieve them.[2]
Other uses of the word hacker exist that are not related to computer security (computer programmer and home computer hobbyists), but these are rarely used by the mainstream media. Some would argue that the people that are now considered hackers are not hackers, as before the media described the person who breaks into computers as a hacker there was a hacker community. This community was a community of people who had a large interest in computer programming, often sharing, without restrictions, the source code for the software they wrote. These people now refer to the cyber-criminal hackers as "crackers"
