Introduction
Penetration testing, also known as pen testing, is a simulated cyber attack on a computer system, network, or web application with the goal of finding vulnerabilities that an attacker could exploit. The purpose of pen testing is to evaluate the security of a system and provide recommendations for improving its security posture.
Penetration testers use a variety of tools to perform their job. Some of the most famous tools used by pen testers include:
Nmap
Nmap, short for Network Mapper, is a free and open-source tool used to discover hosts and services on a computer network. It can be used to map out a network, find open ports, and determine which services are running on a system. Nmap is often used as the first step in a pen testing engagement, as it provides a comprehensive view of the target network.

Metasploit
Metasploit is a powerful and flexible platform for developing, testing, and executing exploits. It includes a large library of pre-written exploits and payloads, making it an essential tool for any pen tester. Metasploit can be used to launch attacks on a target system, allowing the pen tester to evaluate its security posture and find vulnerabilities.

Burp Suite
Burp Suite is a comprehensive platform for web application security testing. It includes a range of tools for conducting penetration tests, including a proxy, a spider, and an intruder. Burp Suite is often used by pen testers to perform vulnerability assessments on web applications and identify security weaknesses.
Wireshark
Wireshark is a free and open-source network protocol analyzer. It can be used to capture and analyze network traffic in real-time, making it an important tool for pen testers. Wireshark can be used to identify network-based attacks and to analyze the behavior of malware on a target system.
Aircrack-ng
Aircrack-ng is a set of tools for auditing wireless networks. It can be used to crack Wi-Fi passwords, intercept wireless traffic, and perform other wireless security assessments. Aircrack-ng is a powerful tool for pen testers looking to evaluate the security of wireless networks.

SQLMap
sqlmap is an open-source tool used for automating SQL injection attacks. SQL injection is a type of web application vulnerability that can be exploited to gain unauthorized access to sensitive data. sqlmap can be used by pen testers to identify SQL injection vulnerabilities in web applications and to test the security of database systems.
John the Ripper:
John the Ripper is a free and open-source password cracking tool. It can be used to crack passwords for a variety of systems, including Windows, Linux, and Mac OS X. John the Ripper is often used by pen testers to evaluate the strength of passwords and to identify weak or easily guessable passwords.
Nessus
Nessus is a commercial vulnerability scanner developed by Tenable. It can be used to scan systems and identify vulnerabilities, including missing patches, misconfigured systems, and weak passwords. Nessus is often used by pen testers to perform vulnerability assessments and to identify security weaknesses in target systems.
OWASP ZAP
OWASP ZAP, short for Open Web Application Security Project Zed Attack Proxy, is a free and open-source web application security scanner. It can be used to identify vulnerabilities in web applications and to test the security of web-based systems. OWASP ZAP is often used by pen testers to identify security weaknesses in web applications and to test their ability to defend against attacks.
Hydra
Hydra is a free and open-source tool used for performing password cracking attacks. It can be used to perform brute-force attacks on a variety of systems, including web applications, FTP servers, and SSH servers. Hydra is often used by pen testers to evaluate the security of passwords and to identify weak or easily guessable passwords.
Conclusion
These are just a few of the most famous tools used by penetration testers. Each tool has its own strengths and weaknesses, and pen testers often use a combination of tools to perform a comprehensive penetration test.
It is important to note that the use of these tools requires a deep understanding of the underlying technologies and a thorough knowledge of security principles. Using these tools without proper knowledge and training can result in serious security incidents, including data breaches and system downtime.
In conclusion, penetration testing is a critical aspect of maintaining the security of computer systems, networks, and web applications. The tools used by penetration testers play a key role in identifying vulnerabilities and evaluating the security posture of target systems. It is important for security professionals to have a solid understanding of these tools and to use them responsibly in order to ensure the security of their systems and data.
