Hackers are not always bad, the word “hacker” does not mean criminal. Geeks and tech writers often refer to black hat and white hat hackers. These terms define hackers based on their behavior.
What is a “Hacker”?
A hacker is a specialist in mastering and understanding IT security and therefore has the means to find these security vulnerabilities and penetrate systems for very specific objectives. Some of them use their skills within a legal framework, however others use it illegally. In the latter case, we speak of black hat hackers.
Black hat hackers are a type of hackers that the media often focus on. These hackers are known to violate computer security for personal gain (theft of credit card numbers from wealthy people). In this case black hat hackers are criminals who carry out illegal activities for personal gain and attack others. They are computer criminals in the truest sense of the word.
White hat pirates are almost the opposite of black hat hackers. They are considered to be ethical hackers, experts in computer security systems who use their capacities, their intelligence and their know-how for good, ethical and legal objectives.
Many hackers are used to test an organization’s computer security systems. And so the organization gives permission to the white hat hacker to try to compromise their systems and resolve a problem.
The white hat hacker uses his security systems capabilities to compromise the organization’s systems, just like a black hat hacker. On the other hand, instead of using their access for bad purposes, the white hat hacker reports to the organization and informs them of how they got there, which alerts the company to improve its defenses . This is called “pentesting” short for penetration testing.
