Tired of weak WiFi passwords and the security risks they pose? Want to implement enterprise-grade security for your home or business network without breaking the bank? This video provides a practical, step-by-step guide to setting up RADIUS authentication using FreeRADIUS and integrating it with Azure Active Directory.

This comprehensive tutorial covers everything you need to know, from basic concepts to advanced configuration, including:

* **Understanding the Risks of WPA2-PSK:** We’ll start by briefly demonstrating how easily WPA2 pre-shared keys can be compromised, highlighting the need for stronger authentication.
* **What is RADIUS and Why You Need It:** We’ll explain the core concepts of RADIUS authentication and how it enhances WiFi security by centralizing user management and enforcing strong authentication policies.
* **Setting up FreeRADIUS on Debian 12:** A detailed walkthrough of installing and configuring FreeRADIUS on a Debian 12 server, including user management and basic configuration.
* **Configuring Your WiFi Access Point for RADIUS:** We’ll show you how to configure your WiFi access point (using a UniFi controller as an example, but the principles apply to most brands) to communicate with your FreeRADIUS server.
* **Integrating FreeRADIUS with Azure AD:** The core of the tutorial: we’ll guide you through the process of connecting your FreeRADIUS server to your Azure AD tenant using OAuth2, allowing you to authenticate WiFi users against your existing Azure user database.
* **Testing and Troubleshooting:** We’ll demonstrate how to test your RADIUS setup and provide tips for troubleshooting common issues.
* **Practical Use Cases:** We’ll discuss real-world scenarios where RADIUS authentication is beneficial, such as home networks, small businesses, and guest WiFi access.
* **Benefits of Azure AD Integration:** We’ll explain the advantages of using Azure AD for WiFi authentication, including centralized user management, enhanced security policies, and single sign-on capabilities.

By the end of this video, you’ll have a fully functional RADIUS server integrated with Azure AD, providing a robust and secure WiFi network. This method eliminates the vulnerabilities of pre-shared keys and provides a scalable and manageable solution for your WiFi security needs.
