Introduction to Hacking

There are various definitions you can get about hacking. Some people will say its illegal some will say it is legal & some will say it is a kind of thefting. Leave it aside, let me tell you what hacking exactly is

Who are Hackers

A Hacker is a person who has excellent knowledge of programming & computer security. He uses his skills to get access into someone’s computer system without letting him know.

Everyone thinks that Hackers are criminals of the Digital World but this is totally wrong . Not all Hackers are criminals. Yes some hackers have malicious intent. Based on this we divide hackers into three common categories.

  • Blackhat Hackers (Crackers)
  • Whitehat Hackers (Ethical Hackers)
  • Greyhat Hackers

    3. Greyhat hackers:-  These are the mixture of both Blackhat hackers & Whitehat hackers. A grey hat hacker can work as a security profession but can also hack someone’s computer without his permission. Although they don’t have malicious intent like Blackhat hackers  but what they did is still illegal.
