[Rhodes22-list] WiFi Security on the Road (or Rhodes) Re: WiFi security

More and more places are offering free WiFi including our marina and 
Annapolis Harbor. When we went on our weeklong cruise we took the 
laptop and free WiFi at one of the marinas allowed us to set up what 
turned out the be a great meeting with Rory and his lovely wife 
Yvonne on Tighlman Island. Unless the new Fed. legislation 
discourages many of these places to give it up WiFi is going to 
become more and more ubiquitous. Even now there are warnings about 
hooking up to WiFi you don't recognize in airports and hotels as 
techy criminals are setting up their own routers in hopes of stealing 
ID and financial info. Criminals with sniffers have already been 
mentioned and are evidently real threats in some places.

So here's the question. One solution I've seen suggested is always 
using a virtual private network for your wireless connections on the 
road. These would (I think) provide the encryption Robert is talking 
about. If you work for a company, they often require that you use 
their VPN on the road. If you have a server at home always connected 
to the Internet you can set up your own VPN. Neither of those 
scenarios applies to us. I've been looking at hosted VPNs where for a 
fee that ranges from $40 to $200 a year you subscribe to someone 
elses VPN service such as Witopia ($40/yr), HotSpotVPN($102/yr) or 
JiWire Hotspot Helper ($25/yr). We already use firewall, antivirus 
and anti-malware tools. Does a hosted VPN work? Does it add another 
layer of security? My reading seems to suggest that it does but am I 
missing something?

Thanks,
Mary Lou
