Classification of Hackers

  1. White Hat : A white hat hacker breaks security for non-malicious reasons, for instance testing their own security system. ‘White hat’ hacker is called an ethical hacker. The International Council of Electronic Commerce Consultants, also known as the EC-Council has developed certifications, courseware, classes, and online training covering the diverse arena of Ethical Hacking.
  2. Blue Hat : A blue hat hacker is someone outside computer security consulting firms who is used to bug test a system prior to its launch, looking for exploits so they can be closed. Microsoft also uses the term Blue Hat to represent a series of security briefing events.
  3. Black Hat : A Black Hat Hacker is a hacker who violates computer security for little reason beyond maliciousness or for personal gain.Black Hat Hackers break into secure networks to destroy data or make the network unusable.
  4. Grey Hat : A grey hat hacker is a combination of a Black Hat and a White Hat Hacker. A Grey Hat Hacker may surf the internet and hack into a computer system for the sole purpose of notifying the administrator that their system has been hacked, for example.Then they may offer to repair their system for a small fee.
