how can I enforce an acceptable level of encryption in wireless device's communication when the
device is "visiting" another network?  For example, if your wireless device "roams" from your network into another network where WEP or WPA is  Not enforced (or available!) how do you still make sure that your data communication is secure?

Any idea where can I find some information.

Thank you,
Edward

Well, for emails you could use PGP... this stands for Pretty good privacy and it can encrypt emails sent over a wireless network. You can download it at www.pgp.com .

You can use a VPN back to your "home" network. This will protect your data regardless of the level of, or lack of, encryption over the air..
PPTP or IPSEC will work.

Then don't use wireless. It's a simple as that.
If they don't even use the most rudementary WEP encryption, I definately would not even think about using that network to transfer sensitive information.
If they have a VPN server, then you could VPN to the server, then all traffic is on the wire from server to endpoint, and encrypted from server to you.

As has been said VPN is the way to go. You contorl the encrypion from your client to your network (IE Security).
You are not depending on somone else for part of your security that you may not know.
