Analyzing and Testing Wi-Fi Captive Portals

Public Wi-Fi networks often rely on captive portals to restrict access, but these systems frequently suffer from fundamental design weaknesses. This written course helps you understand how captive portals function at the protocol level, how security analysts evaluate their robustness, and how to defend them against unauthorized access. By studying the underlying network behaviors, you will gain a clear perspective on wireless gateway security. What you'll learn: - Understand the core HTTP redirection and DNS mechanics behind captive portals - Analyze the security implications of MAC address spoofing and session tracking - Explore the theory behind DNS and ICMP tunneling techniques - Learn modern secure authentication methods and WPA3 transition strategies - Implement robust administrative defenses to secure public networks Starting with essential networking definitions and terminal concepts, the text guides you step-by-step through conceptual analysis scenarios and mitigation strategies. This course is designed for beginners and entry-level network administrators, with no prior security experience required. Expand your network security knowledge and start reading today.
