Hello
From my research Make sure you use HTTPS:// websites and the "lock" icon is visible on the bottom right of every webpage!!

First, be aware that (almost) ANYTHING that you type or any info that appears on your screen while you're using a wireless connection can be seen by others nearby.

If you are accessing a page that requires a login and password, or if you are entering ANY personal data (credit card, SSN, etc) make sure that you are on a secure site. That's easy enough -- just check that the web address begins with https instead of the usual http -- and your information will be safely encrypted before transmission. As long as you're on a page with an address that begins with https, the data you send and receive is protected from sniffers and snoopers.

But be on your guard, some web-based email providers have a secure login page, but after you're logged in the access reverts to normal non-encrypted mode. So any email you send or receive while on a wireless connection is out in the clear. Google's GMail and Yahoo Mail are examples of webmail services that work this way. Until recently Hotmail didn't even offer a secure login option. So look for the link or checkbox for the secure login when accessing your web-based email. If your service doesn't offer one, consider switching or decide to live with the security exposure.
