Overview of this book

As Linux continues to gain prominence, there has been a rise in network services being deployed on Linux for cost and flexibility reasons. If you are a networking professional or an infrastructure engineer involved with networks, extensive knowledge of Linux networking is a must. This book will guide you in building a strong foundation of Linux networking concepts. The book begins by covering various major distributions, how to pick the right distro, and basic Linux network configurations. You'll then move on to Linux network diagnostics, setting up a Linux firewall, and using Linux as a host for network services. You'll discover a wide range of network services, why they're important, and how to configure them in an enterprise environment. Finally, as you work with the example builds in this Linux book, you'll learn to configure various services to defend against common attacks. As you advance to the final chapters, you’ll be well on your way towards building the underpinnings for an all-Linux datacenter. By the end of this book, you'll be able to not only configure common Linux network services confidently, but also use tried-and-tested methodologies for future Linux installations.

Summary

This concludes our journey into using RADIUS for authentication of various servers. As with many of the Linux services we've explored in this book, this chapter just scratches the surface of common configurations, use cases, and combinations that RADIUS can be used to address.

At this point, you should have the expertise to understand how RADIUS works and be able to configure secure RADIUS authentication for VPN services and administrative access, as well as wireless and wired network access. You should have the basics to understand the PAP, CHAP, LDAP, EAP-TLS, and 802.1x authentication protocols. The EAP-TLS use cases, in particular, should illustrate why having an internal CA can really help in securing your network infrastructure.

Finally, we touched on integrating Google Authenticator with RADIUS for MFA. We didn't cover the detailed configuration of the Google Authenticator service, though—this seems to be changing so frequently of late that the...
