IN THIS CHAPTER
Security is a big concern for mobile Wi-Fi users, as it ought to be. It's a fact of life, however, that most problems with mobile computing do not have to do with technology, but rather with human interactions. Perhaps someone sees you entering confidential information in your Centrino laptop while you are "Wi-Fiing" in a hotel lobby or a crowded airport waiting area. Or, it can be as simple as theft of a laptop computer. These issues are not much different because your laptop is equipped with Wi-Fi. (Someone can still read confidential information over your shoulder even if you are not unwired.) But it is a fact of life that mobile computers equipped with Wi-Fi do get out and about moreso security is an even bigger concern for them than for the run-of-the-mill nonWi-Fi laptop. It is also the case that special security risks are involved with using a laptop at a public hotspot.
This chapter explains the dos and the don'ts of traveling with a Wi-Fienabled laptop. I'll tell you what you can do to protect yourself and your equipment. I'll also tell you what software you should be running to Wi-Fi with the best of themfor fun and profit, but most of all, safely.
