Building Vpns

The authors meet the growing demands of de-centralized companies that need a secure and functional network using Linux. The only book available that extensively covers the combination of VPN technology and Linux, this volume teaches first hand how to build various VPN solutions with individual setup guides.

Several trends are hastening the use of MPLS-based VPNs in broadband networks. With this rapid evolution, networking professionals need resources like this new volume.

Learn how to build your own VPN server in the cloud or on a Raspberry Pi This book is a step-by-step guide to building your own IPsec VPN, OpenVPN and WireGuard server. Based on 10 years of open source work with millions of users, this book will help you build your own VPN in just a few minutes, even if you haven't set up a server or used a VPN before. By reading this book you will learn how to: ✔ Create a cloud server on DigitalOcean, Vultr, Linode and OVH ✔ Connect using SSH and set up WireGuard, OpenVPN and IPsec VPN with IKEv2 ✔ Configure VPN clients on Windows, macOS, Android and iOS ✔ Manage WireGuard, OpenVPN and IKEv2 VPN clients In the digital age, cyber security and privacy are more important than ever. Using a virtual private network (VPN) can help improve your cybersecurity and privacy by encrypting your network traffic, so that your data is protected as it travels via the Internet. This is especially useful when using unsecured Wi-Fi networks, such as at coffee shops, airports or in hotel rooms. Creating your own VPN server has become easier than ever, thanks to advances in technology such as affordable cloud servers and reduced bandwidth costs. Self-hosted VPNs can be considerably cheaper than commercial ones and offer several advantages. The VPN setup process can be fully automated and as simplified as possible. This book will help you build your own VPN server in the cloud or on a Raspberry Pi in just a few minutes. Get your copy of this book today and start building your own VPN!

EASY-TO-FOLLOW EXAMPLES FOR SECURE, VERSATILE, COST-CUTTING, VALUE-ADDED VPNs With the security enhancements, flexibility, and market advantages now available with IPSec and MPLS, building mission-critical VPNs using these technologies has become a top agenda for many networking professionals. LEVERAGE THE BENEFITS OF IPSec AND MPLS Assembling a fully functional IPSec or MPLS VPN isn’t easy. With so little information available it can be like trying to build a bicycle when you have all the components, but no idea what the final product should look like. Only Building VPNs shows, in a clear, step-by-step fashion, how to build VPNs from scratch with IPSec and MPLS. Building VPNs: With IPSec and MPLS gives you: * From-the-ground-up directions for VPN construction * Step-by-step implementation of IPSec for secure, inexpensive, transmission of sensitive information across the public Internet * Easy-to-follow, diagrammed directions for deploying MPLS VPNs to provide value-added managed services * Clear instructions for using IPSec and MPLS in the enterprise and service-provider networking environments * Fully working solutions for both basic and advanced VPN issues * Examples that clarify every important step in VPN design, configuration, implementation, and deployment THE BOOK TO CHOOSE FOR VPN BUILDS

Virtual Private Networks (VPNs) are a cheap and secure way for companies to transmit information over the Internet. With implementation of two new protocols, IPSec and MPLS, VPNs are about to become standard operating procedure. This guide aims to teach network engineers and architects, internetworking pros in the enterprise and service provider organisations and security pros working on VPNs as a corporate security measure how to use them. It walks readers through a VPN build from the ground up and demonstrates how IPSec and MPLS can be used in conjunction.

An increasing number of companies are designing and implementing Remote Access Networks, which allow users who are not physically connected to a Wide Area Network (WAN) or Local Area Network (LAN) to access the network's servers, applications and databases or to participate in video conferencing and conference calls. The ability for a remote user to function as if they were in the next office dramatically improves overall efficiency while reducing total cost of ownership. Cisco Systems, the world's largest internetworking vendor, is the pioneer of the enabling technologies for Remote Access Networks. This book will identify and explain all of the Cisco products necessary for designing and building a remote access network and integrating it with legacy systems. This book is a professional reference detailing all of the strategies, tactics and methods for designing, configuring and maintaining Cisco Remote Access Networks. It will include thorough discussions of all Cisco Access Servers and routers. * Demand for information on remote access networks is growing quickly at corporate and administrator level * Cisco remote access networks appeal to businesses as they provide efficient and secure connectivity at reduced cost * Book includes thorough discussions of all Cisco Access Servers and routers

Provides a step-by-step approach for planning and implementing a wireless LAN based on 802.11 Wireless Fidelity (Wi-Fi) technology Authors are Wi-Fi security experts who are able to address the firestorm of concerns about security for 802.11b networks Offers a clear perspective of interoperability with related wireless standards like 802.11a, HomeRF, and Bluetooth Explains how to achieve the same performance as a wired Ethernet connection and deliver flexibility and high speed

From the Foreword: "This book lays out much of what we’ve learned at AT&T about SDN and NFV. Some of the smartest network experts in the industry have drawn a map to help you navigate this journey. Their goal isn’t to predict the future but to help you design and build a network that will be ready for whatever that future holds. Because if there’s one thing the last decade has taught us, it’s that network demand will always exceed expectations. This book will help you get ready." —Randall Stephenson, Chairman, CEO, and President of AT&T "Software is changing the world, and networks too. In this in-depth book, AT&T's top networking experts discuss how they're moving software-defined networking from concept to practice, and why it's a business imperative to do this rapidly." —Urs Hölzle, SVP Cloud Infrastructure, Google "Telecom operators face a continuous challenge for more agility to serve their customers with a better customer experience and a lower cost. This book is a very inspiring and vivid testimony of the huge transformation this means, not only for the networks but for the entire companies, and how AT&T is leading it. It provides a lot of very deep insights about the technical challenges telecom engineers are facing today. Beyond AT&T, I’m sure this book will be extremely helpful to the whole industry." —Alain Maloberti, Group Chief Network Officer, Orange Labs Networks "This new book should be read by any organization faced with a future driven by a "shift to software." It is a holistic view of how AT&T has transformed its core infrastructure from hardware based to largely software based to lower costs and speed innovation. To do so, AT&T had to redefine their technology supply chain, retrain their workforce, and move toward open source user-driven innovation; all while managing one of the biggest networks in the world. It is an amazing feat that will put AT&T in a leading position for years to come." —Jim Zemlin, Executive Director, The Linux Foundation This book is based on the lessons learned from AT&T’s software transformation journey starting in 2012 when rampant traffic growth necessitated a change in network architecture and design. Using new technologies such as NFV, SDN, Cloud, and Big Data, AT&T’s engineers outlined and implemented a radical network transformation program that dramatically reduced capital and operating expenditures. This book describes the transformation in substantial detail. The subject matter is of great interest to telecom professionals worldwide, as well as academic researchers looking to apply the latest techniques in computer science to solving telecom’s big problems around scalability, resilience, and survivability.
