First hackers and hacker technology

(a) sources of hackers

"Hacker" is a term coined by the English translation of the Hacker, is a specialized research, computer and network vulnerability of computer enthusiasts. They are accompanied by the development of computer and network have grown, hackers basically is a hobby, usually for their own interests, rather than to make money or work. The word "hacker" outside the circle or the media is usually defined as: dedicated to invade others system illegal computer master. But this kind of person in the eyes of hacker belongs to the lower level cracker (hackers).

The hacker began in the nineteen fifties, the earliest computer at the University of Pennsylvania in 1946, and the earliest hackers appeared in the Massachusetts academy, Baer laboratory have. The original hackers are generally some senior technical staff, they are keen to share in the challenge, advocating freedom and claim information.

(b)The hacker technology

Hacker technology, is on the computer system and network of flaws and vulnerabilities discovered, and the technical implementation of attacks against these defects. Here said the defects, including defects in software, hardware, network protocol flaws, defects management defects and human error. Obviously, hackers technical ability to network with destruction.

Engaged in illegal destruction activities for personal gain by hacker technology, behoove is spurned by the people's behavior. This kind of person not to focus on research and repair found on the system defects, but for some purpose to intrusion system, steal information, misappropriation of authority and implementation of sabotage. Can be said that the hacker technology exists to produce network security industry. Internet is based on the TCP/IP protocol, network equipment and operating system with networking capability. The TCP/IP protocol has some inherent design flaws, many even
