Connecting to the Internet at a wireless hotspot can be hazardous to your computer's health. Even worse, your (and your organization's) sensitive information can be put at serious risk if your computer and communications channel are not locked down and protected against the elements whenever you log on at your favorite local hotspot.
A controlled network environment is bad enough, but when you're connected to the Internet wirelessly among a bunch of strangers, it's like swimming among sharks -- you never know when someone is going to attack. This is true in "open access" hotspots (which I'm seeing more and more of) and even at "trusted access" hotspots that require you to subscribe and authenticate before obtaining access.
All it takes is someone with a wireless network analyzer to see what's going on. Add to that a few basic hacking tools and your computer can be "owned" by someone else in a matter of minutes. Take the following steps to ensure that your wireless laptop is locked down. That way you can keep the good stuff in and the bad guys out the next time you connect wirelessly in a public place.
How to lock down laptops that connect to hotspots
Step 1: Understand what there is to lose and who's stealing the loot
Step 2: Secure your computer to prevent attacks in the first place
Step 3: Secure your communications link
Step 4: Tools you can use to test if you're vulnerable
