Pages : 374

Book Description
Let’s face it: the information age makes dummies of us all at some point. One thing we can say for sure, though, about things related to the Internet is that their best strengths are often also their worst weaknesses. This goes for virtual private networks (VPNs). They may reach a wide base of customers – but can also be vulnerable to viruses, hackers, spoofers, and other shady online characters and entities. VPNs may allow for super-efficient communication between customer and company – but they rely on information which, if compromised, can cause huge losses. The Internet is still a frontier – sometimes so wide open it leaves us bewildered – and, like any frontier, the risks go hand in hand with potentially huge rewards. Virtual Private Networks for Dummies offers you a no-nonsense, practical guide to evaluating your company’s need for a VPN, understanding what it takes to implement one, and undertaking the challenging quest to set it up, make it work, and keep it safe. Whether you’re the resident expert leading the project team, or you just want to learn what makes e-commerce tick, this detailed, from-the-ground-up guide will soon have you comfortably conceptualizing: Security goals and strategies The evolution of VPNs Privacy in VPNs Extranets Remote-Access VPNs Funding Custom network solutions design Testing VPNs And more With new products and technologies offering supposedly revolutionary solutions to IT departments every day, this book focuses on the real world – you know, the one full of obstacles, mishaps, threats, delays, and errors – and gives you the background knowledge to make decisions for yourself about your VPN needs. Written with a dash of humor, Virtual Private Networks for Dummies contains both technical detail (standards, protocols, etc.) and more general concepts (such as conducting cost-benefit analyses). This clear, authoritative guide will have you securely and cost-effectively networking over the Internet in no time.

This book is the study guide and textbook for the TCO Certified Telecommunications Network Specialist (CTNS) Certification, conforming to the lessons in the eight CTNS courses and their exams: 2241 Introduction to Broadband Converged IP Telecom 2206 Wireless Telecommunications 2221 Fundamentals of Voice over IP 2201 The PSTN 2212 OSI Layers and Protocol Stacks 2211 LANs, VLANs, Wireless and Optical Ethernet 2213 IP Addresses, Packets and Routers 2214 MPLS and Carrier Networks The selection of material, its order, timing, and explanations are field-tested to deliver the core knowledge set for today’s telecommunications. The courses deliver a solid foundation of knowledge in broadband, telecom, datacom and networking: the fundamentals, technologies, jargon and buzzwords, standard practices and most importantly, the underlying ideas, and how it all fits together… with TCO Certification to prove it! The first four CTNS courses are on telecommunications, beginning with Introduction to Broadband Converged IP Telecom, an introduction and first pass through all of the topics; followed by Wireless Telecommunications, then Introduction to Voice over IP, and The PSTN. The second half of CTNS is four courses focusing on the three main enabling technologies for the modern telecom network: Ethernet, IP and MPLS. We begin with the OSI model and its Layers to establish a framework for understanding what each does and how they work together... and all the other things that have to be done. This book is intended to enhance your learning and retention while taking the online courses. It is also useful as a day-to-day reference handbook and glossary. Our goal is to explain the big picture, the jargon and buzzwords, and put in place a very solid base of telecom knowledge spanning fundamentals to the latest technologies and how they are deployed – in plain English.
