Network penetration testing, also known as ethical hacking or white-hat hacking, is a security assessment practice that involves simulating real-world attacks on a computer network to identify vulnerabilities and assess the network's overall security posture. The goal of network penetration testing is to proactively identify weaknesses in the network infrastructure, systems, and applications that could be exploited by malicious attackers.
During a network penetration test, a team of skilled cybersecurity professionals, known as penetration testers, conducts a controlled and authorized attempt to exploit vulnerabilities within the network. They employ a variety of tools, techniques, and methodologies to identify and exploit security weaknesses, just as a real attacker would.
The penetration testers typically follow a systematic approach that includes reconnaissance, scanning, gaining access, maintaining access, and covering tracks. They may employ methods such as vulnerability scanning, social engineering, password cracking, network sniffing, and exploitation of misconfigurations or software vulnerabilities.
