Description

Security on the internet is increasingly vital to both businesses and individuals. Encrypting network traffic using Virtual Private Networks is one method to enhance security. The internet, corporate, and “free internet” networks grow more hostile every day. OpenVPN, the most widely used open source VPN package, allows you to create a secure network across these systems, keeping your private data secure. The main advantage of using OpenVPN is its portability, which allows it to be embedded into several systems. This book is an advanced guide that will help you build secure Virtual Private Networks using OpenVPN. You will begin your journey with an exploration of OpenVPN, while discussing its modes of operation, its clients, its secret keys, and their format types. You will explore PKI: its setting up and working, PAM authentication, and MTU troubleshooting. Next, client-server mode is discussed, the most commonly used deployment model, and you will learn about the two modes of operation using "tun" and "tap" devices. The book then progresses to more advanced concepts, such as deployment scenarios in tun devices which will include integration with back-end authentication, and securing your OpenVPN server using iptables, scripting, plugins, and using OpenVPN on mobile devices and networks. Finally, you will discover the strengths and weaknesses of the current OpenVPN implementation, understand the future directions of OpenVPN, and delve into the troubleshooting techniques for OpenVPN. By the end of the book, you will be able to build secure private networks across the internet and hostile networks with confidence.

VPN is an exciting topic for me, but I've had difficult to use it, I was searching for this but some information that I've found aren't for beginners, or are just bad resources, this book explain since the basic concepts, throughout the differences between VPN's, the new features and we know that when we deal with security we have to use the most updated resource, this book gives me a handfull knowledge about OpenVPN, I am not a professional yet, but all the things this book show makes me understand and feel confortable about its configurations, I know that real life projects must be more problematic, but I enjoyed every chapter, I don't had used BSD in the past so I just tried on my Linux and Windows house machines network, I liked the usage in mobile devices and home routers since this is my actual needs, and the part of the log files, even following the book I've missed few details during the configuration, and this log files are hard to me before.

Love reading the book. Learned a lot about configuring OpenVPN

Totempole Oct 18, 2015

This is the go-to book for going from learning everything about OpenVPN. Not only that, but it walks you through the basics, it tells you what a VPN is, the types of VPNs, their pros and cons. This is the book for everyone looking into mastering OpenVPN, from the home user (setting it up in your own router, and using your mobile devices as clients) to the network admin (client/server setup).

Finally a comprehensive and up-to-date book (Aug. 2015) on OpenVPN. The concepts and available options behind the implementation of virtual private networks using OpenVPN are well explained and worked out with several examples. The book is complete and self-contained. No previous knowledge on OpenVPN is required. Personally, I found Chapter 7 (Scripting and Plugins) extremely helpful: understanding the exact order in which all different scripts are executed is what helped me the most with the implementation of (powerful!) vpn solutions. The book has few typos in some of the worked out examples but they can easily be spotted out.

This book is targeted to system administrators willing to deploy an extra layer of security for his users or customers which need to access private infraestructures from the internet using OpenVPN software. This book it's written in plain language and goes straight to the point but a good knowledge on networking is advised to get the most out of the book. The book can be used as a complete guide to deploy the service from the ground or to strengthen security or fine tune already existing VPN scenarios. The book also gives recommendations on how to scale in the future and be aware of possible weaknesses of the system. In overall it's a very good source of information on this matter and I recommend it without any doubt.
