What is Penetration Testing, and How Does it Work?

Penetration testing, or “pen testing,” is testing a computer system, network, or web application to find security vulnerabilities. Penetration testing is normally performed by ethical hackers who attempt to exploit weaknesses in the system to get unauthorized access or steal sensitive data.

During the planning phase, the penetration testing team will define the scope of the test and determine the goals and objectives. The reconnaissance phase involves gathering information about the target system, such as IP addresses, open ports, and operating systems.

In the attack phase, the penetration testing team will attempt to exploit system vulnerabilities using the best penetration testing tools and techniques. Finally, the reporting phase provides a detailed report of the vulnerabilities found and recommendations for mitigating them.
