This module explores the architectural evolution of enterprise wireless networks, transitioning from standalone Autonomous Access Points to centralized Controller-Based architectures. You will learn how Wireless LAN Controllers (WLCs) manage lightweight APs using protocols like CAPWAP, centralizing configuration, RF management, and security policies through the "Split-MAC" architecture. From a cybersecurity perspective, you will discover how WLCs act as the central enforcement point for wireless access, enabling features like dynamic VLAN assignment, rogue AP detection, and centralized authentication (802.1X/RADIUS), while also understanding the critical risks if the control plane is compromised.
