Contents of This Book
- Chapter 1
Do you need a virtual private network? Good question. Read this chapter and find out. After we scare you with some common security breaches, you will find some comforting reasons why a virtual private network may be your solution.
- Chapter 2
Still here? This chapter details the various pieces that make a VPN function and make it more secure. Firewalls, encryption/authentication, and some basic VPN protocols and standards are covered. Rounding out this chapter are some of the varied and fun encryption technologies, such as Data Encryption Standard (DES), the RSA Public Key Cryptosystem, IPSec, and Secure Socket Layer (SSL).
- Chapter 3
How much is this going to cost me? Justifying the cost of all these technologies is possible once you delve into the exciting world of VPN bean counting. In this chapter, the VPN’s costs and benefits are weighed against the more traditional solutions: private lease-line Wide Area Network (WAN) and remote access. The three solutions are compared through a comprehensive breakdown of equipment, lines, personnel, and—most importantly—time. Prices may vary. Check your local listings for a showing near you.
- Chapter 4
What’s a specific solution for my VPN? Well, there are several. We start with one of the cheapest versions (free!): Point-to-Point Tunneling Protocol, or, as we call it in the industry, PPTP. PPTP has recently been updated and broadened into the L2TP protocol—but the two are used the same way.
