An ethical hacker (also known as a white hat hacker) is the ultimate security professional. Ethical hackers know how to find and exploit vulnerabilities and weaknesses in various systems—just like a malicious hacker (or a black hat hacker). In fact, they both use the same skills; however, an ethical hacker uses those skills in a legitimate, lawful manner to try to find vulnerabilities and fix them before the bad guys can get there and try to break in.
An ethical hacker’s role is similar to that of a penetration tester, but it involves broader duties. They break into systems legally and ethically. This is the primary difference between ethical hackers and real hackers—the legality.
What is ethical hacking?
Apart from testing duties, ethical hackers are associated with other responsibilities. The main idea is to replicate a malicious hacker at work and instead of exploiting the vulnerabilities for malicious purposes, seek countermeasures to shore up the system’s defenses. An ethical hacker might employ all or some of these strategies to penetrate a system:
Detecting how well the organization reacts to these and other tactics help test the strength of the security policy and security infrastructure. An ethical hacker attempts the same types of attacks as a malicious hacker would try—and then help organizations strengthen their defenses.
