What Is Hacking And Types Of Hackers .

Hacker is a term that has been used to mean a variety of different things in computing. Depending on the context, the term could refer to a person in any one of several distinct (but not completely disjointed) communities and subcultures.

Hacking means finding out weaknesses in a computer or computer network, though the term can also refer to someone with an advanced understanding of computers and computer networks.Hackers may be motivated by a multitude of reasons, such as profit, protest, or challenge.The subculture that has evolved around hackers is often referred to as the computer underground but it is now an open community.While other uses of the word hacker exist that are not related to computer security, they are rarely used in mainstream context. They are subject to the long standing hacker definition controversy about the true meaning of the term hacker. In this controversy, the term hacker is reclaimed by computer programmers who argue that someone breaking into computers is better called a cracker,not making a difference between computer criminals (black hats) and computer security experts (white hats). Some white hat hackers claim that they also deserve the title hacker, and that only black hats should be called crackers.

As far as we know, there's three types of hacker we can see :

Grey Hat : A grey hat, in the hacking community, refers to a skilled hacker whose activities fall somewhere between white and black hat hackers on a variety of spectra. It may relate to whether they sometimes arguably act illegally, though in good will, or to show how they disclose vulnerabilities. They usually do not hack for personal gain or have malicious intentions, but may be prepared to technically commit crimes during the course of their technological exploits in order to achieve better security.Whereas white hat hackers will tend to advise companies of security exploits quietly, grey hat hackers are prone to "advise the hacker community as well as the vendors and then watch the fallout"

White Hat : The term "white hat" in Internet slang refers to an ethical hacker, or a computer security expert, who specializes in penetration testing and in other testing methodologies to ensure the security of an organization's information systems.Ethical hacking is a term coined by IBM meant to imply a broader category than just penetration testing.White-hat hackers are also called "sneakers",red teams, or tiger teams.

Black Hat : A Black Hat Hacker is a hacker who "violates computer security for little reason beyond maliciousness or for personal gain" (Moore, 2005).Black Hat Hackers form the stereotypical, illegal hacking groups often portrayed in popular culture, and are "the epitome of all that the public fears in a computer criminal".Black Hat Hackers break into secure networks to destroy data or make the network unusable for those who are authorized to use the network. They choose their targets using a two-pronged process known as the "pre-hacking stage".
