Organizations hire cybersecurity experts to test their security and defenses to explore weak points in IT architecture. Professionals who perform ethical hacking are known as White hat hackers. On the other hand, black hat practices involve illegal security breaches that can harm systems or compromise information. Still, the techniques used by white hat hackers and black hat hackers are the same, differing only in the intent.

Roles and responsibilities for ethical hacking professionals vary from organization to organization. Skills for ethical hacking include knowledge of programming, scripting, networking, and understanding databases, platforms, search engines, and servers.

Ethical hackers have the responsibility to create scripts, develop tools, set security concepts, perform a risk analysis, and train staff to use all the safety measures in their operations. Penetration testing is an essential part of ethical hacking, with its primary aim being to penetrate information systems.
