Ethical hacking is a security practice where a hired hacker, either an individual or an appointment within a company, attempts to break into a system, simulating a malicious cyber-attackers action.The ethical hacker, colloquially known as a white hat hacker, is typically a computer security expert specializing in pen testing, penetration testing, and other testing methodologies.
Ethical hacking plays an essential role in checking for weaknesses and entry points in a network, infrastructure, and web application security. A white hat hacker uses the same methods as a malicious hacker would use. The ethical hacker's goal is to test the safety of an organization's information systems to improve their security. Given the value of ethical hacking, especially considering the damage caused by a successful malicious hacking, there is increasing interest in deploying ethical hackers to combat today’s cyber threats.
The main types of ethical hacking include:
White Hat Hackers (also known as Ethical Hackers) -They never intended to harm a system; instead, they try to find out weaknesses in a computer or a network system as a part of penetration testing and vulnerability assessments. These hackers aren't doing anything illegal, and it's usually done as their job.
Black Hat Hackers (also known ascrackers)hack to gain unauthorized access to a system and harm its operations or steal sensitive information. This is illegal as they intend to do bad things, including stealing corporate data, violating privacy, or damaging the system.
Grey Hat Hackers– These area blend of both black hat and white hat hackers. They act without malicious intent, but for their fun, they exploit a security weakness in a computer system or network without the owner's permission or knowledge but plan to let the owner know of the defect.
