Chapter 1. Introduction to AAA and RADIUS
It is my pleasure to present you a beginner's guide to FreeRADIUS. This book will help you to deploy a solid, stable, and scalable RADIUS server in your environment.
This chapter is used as an introduction to RADIUS and FreeRADIUS. We will be covering a fair amount of theory and recommend you pay special attention to it. This will supply you with a good foundation on the workings of the RADIUS protocol and will be of much help in subsequent chapters.
In this chapter we shall:
- See what AAA is, and why we need it
- Learn where RADIUS started and why it is so relevant today
- See why FreeRADIUS really shines as a RADIUS server
- Understand the relationship between AAA, RADIUS, and FreeRADIUS
Let's get started.
