1 ) White Hat Hackers
They are the good guys in the cyber world.They exploit a computer system or a web server to find loopholes and then they patch those loopholes for good.
They help in stopping the cyber crimes.There is a scarcity of white hat hackers in the IT world.Companies are ready to pay huge amount of money to protect their sites,servers etc.So be one of them.Become a white hat hacker.
