Penetration testing, often referred to as pen testing, is a security assessment technique used to identify vulnerabilities in computer systems, networks, and applications. The purpose of pen testing is to simulate an attack on a system or network to identify potential security weaknesses that could be exploited by cybercriminals.
Penetration testing can be carried out in various ways, such as white box, black box, or gray box testing. In white box testing, the tester has full knowledge of the system or network being tested, while in black box testing, the tester has no knowledge of the system or network being tested. Gray box testing is a combination of both, where the tester has some knowledge of the system or network being tested.
