A security hacker is someone who explores methods for breaching defenses and exploiting weaknesses in a computer system or network. Hackers may be motivated by a multitude of reasons, such as profit, protest, information gathering, challenge, recreation, or evaluation of a system weaknesses to assist in formulating defenses against potential hackers. The subculture that has evolved around hackers is often referred to as the “computer underground”.
Classification of security hacker:-
Hackers can be classified into three different categories:
- Black Hat Hacker
- White Hat Hacker
- Grey Hat Hacker
Black Hat Hacker:-
Another name is Unethical Hacker or a Security Cracker. These people hack the system illegally to steal money or to achieve their own illegal goals. They find banks or other companies with weak security and steal money or credit card information. They can also modify or destroy the data as well. Black hat hacking is illegal.
White Hat Hacker:-
Also called as Ethical Hackers or a Penetration Tester. White hat hackers are the good guys of the hacker world.
These people use the same technique used by the black hat hackers. They also hack the system, but they can only hack the system that they have permission to hack in order to test the security of the system. They focus on security and protecting IT system. White hat hacking is legal.
Gray Hat Hacker:-
Gray hat Hackers are Hybrid between Black hat Hackers and White hat hackers. They can hack any system even if they don’t have permission to test the security of the system but they will never steal money or damage the system.
In most cases, they tell the administrator of that system. But they are also illegal because they test the security of the system that they do not have permission to.
Importance of Ethical hacking:-
- Hackers can think from an attacker’s perspective and find the potential entry point and fix them before any attacks.
- Ethical hacking helps us learn new skills used in many roles like software developer, risk management, quality assurance tester, and network defender.
- In a company, the trained ethical hackers are the main strength. To ensure the functions of software aptly, ethical hackers can apply quick security tests under extreme and standard conditions.
Ethical hackers develop many tools and methods and quality assurance tester to eliminate all the system’s vulnerabilities.
