Introduction to Hacking

There are many definitions for “hacker.” Ask this question from a phalanx and you’ll get a new answer every time because “more mouths will have more talks” and this is the reason behind the different definitions of hackers which in my opinion is quite justified for everyone has a right to think differently.
In the early 1990s, the word “hacker” was used to describe a great programmer, someone who was able to build complex logics. Unfortunately, over time the word gained negative hype, and the media started referring to a hacker as someone who discovers new ways of hacking into a system, be it a computer system or a programmable logic controller, someone who is capable of hacking into banks, stealing credit card information, etc. This is the picture that is created by the media and this is untrue because everything has a positive and a negative aspect to it. What the media has been highlighting is only the negative aspect; the people that have been protecting organizations by responsibly disclosing vulnerabilities are not highlighted.
However, if you look at the media’s definition of a hacker in the 1990s, you would find a few common characteristics, such as creativity, the ability to solve complex problems, and new ways of compromising targets. Therefore, the term has been broken down into three types:
1. White hat hacker—This kind of hacker is often referred to as a security professional or security researcher. Such hackers are employed by an organization and are permitted to attack an organization to find vulnerabilities that an attacker might be able to exploit.
2. Black hat hacker—Also known as a cracker, this kind of hacker is referred to as a bad guy, who uses his or her knowledge for negative purposes. They are often referred to by the media as hackers.
3. Gray hat hacker—This kind of hacker is an intermediate between a white hat and a black hat hacker. For instance, a gray hat hacker would work as a security professional for an organization and responsibly disclose everything to them; however, he or she might leave a backdoor to access it later and might also sell the confidential information, obtained after the compromise of a company’s target server, to competitors.
