This course aims to equip you with the essential knowledge and skills to understand cybersecurity and identify vulnerabilities that could be exploited by attackers—ethically and safely. It begins by explaining the structure of the web and protocols like HTTP, then moves on to fundamental concepts such as request methods, cookies, and sessions, which are key to understanding how browsers and servers communicate. You'll also explore common types of web attacks, including spoofing, path traversal, SQL injection, and techniques like Local and Remote File Inclusion (LFI/RFI). The course then shifts focus to a critical area—WiFi security. You'll learn about different encryption methods and how to test the security of wireless networks. Additionally, it covers the basics of mobile application penetration testing through hands-on labs that simulate real-world scenarios. This course is designed for beginners in a simple and practical way, helping you build a strong foundation in the field of cybersecurity.
