Network Traffic Analysis and MITM Simulation with Charles Proxy

Have you ever wondered how data travels between your applications and the web, or how vulnerable that data is to interception? Understanding how to inspect network traffic and simulate security threats is essential for modern developers, QA testers, and security enthusiasts. This text-based course guides you through the fundamentals of network debugging and security analysis. You will learn how to intercept, decrypt, and manipulate web traffic using Charles Proxy, giving you the practical knowledge to identify vulnerabilities and secure your applications against real-world threats. What you'll learn: - Understand the core concepts of HTTP/HTTPS protocols and how proxy servers intercept data - Configure Charles Proxy to capture and decrypt secure SSL/TLS traffic - Analyze API requests and responses to debug application behavior and identify data leaks - Simulate Man-in-the-Middle (MITM) attacks to test how your applications handle intercepted traffic - Practice rewrite rules and breakpoints to manipulate network requests on the fly - Explore the basics of SSL pinning and how to assess application resilience against interception You will start by mastering foundational networking concepts and proxy setup before moving into hands-on traffic inspection, request manipulation, and security testing scenarios. This course is designed for beginners in web development, quality assurance, or cybersecurity, with no prior experience in network analysis required. Start reading today to demystify network traffic and build more secure web applications.
