Learning Basis: Understand the basic concepts, principles and technologies of network security, including network protocols, Web application security and common attack methods.

Learning programming languages: Penetration testing requires certain programming skills, especially mastering one or more scripting languages (such as Python, JavaScript, etc.). ) and common programming concepts and skills.

Learn penetration testing tools: Understand and master commonly used penetration testing tools, such as Nmap, Metasploit, Wireshark, etc. These tools can help you quickly identify and exploit security vulnerabilities.

Learning attack techniques: Learn various attack techniques, such as SQL injection, cross-site scripting attack (XSS) and cross-site request forgery (CSRF), and how to use these vulnerabilities to gain unauthorized access, steal sensitive data or execute malicious code.

Learn defensive measures: learn how to defend against common network attacks and exploits, including installing and configuring security software, updating and maintaining security patches for operating systems and applications, etc.

Learning laws and regulations: Penetration testing needs to abide by relevant laws and regulations and ethics, understand and abide by the laws and regulations of various countries and regions, and avoid breaking the law.

Attend training courses: Attend professional penetration testing training courses, and you can systematically learn the principles, techniques and methods of penetration testing, as well as practical experience and skills.

Participate in community activities: join relevant cyber security communities or organizations, exchange experiences with other security professionals, and learn about the latest security trends and technical progress.

In a word, learning penetration testing requires extensive network security knowledge and skills, and requires continuous learning and practice. Through continuous study and practice, you can improve your penetration test ability and become a professional in the field of network security.
