When away from home I would like to use internet cafe's for the odd email, and check my bank accounts, but I am afraid to do so. Is there any way I can protect myself from my security being breached? I do not use a laptop with a wireless connection.

Good advice as always, Leo. I'd like to add that even though you have a Firewall running, make sure that you lock it down by disabling Exceptions when you are using a public LAN. I just got attacked that way in a library!

Could LogMeIn (their free version) be used effectively as a VPN? I log on at their site and I then connect to my home computer and remote control it to do all of my Internet business. Is this an effective way to keep people from seeing what I'm doing when I'm accessing the Internet at a hotel?

Yes. I've been meaning to play with the free LogMeIn (I also use LogMeIn Hamachi, which when coupled with Windows own Remote Desktop can also do the same).

Leo, every week I read and get a lot of excellent advice on your column. But you can get CLEAR signals a lot further than 100 meters away. I have my own connection (Verizon Wireless), but the person who rented this place before me mounted a wi-fi antenna on top of the unused chimney (a huge square one), the library is eight blocks away, and I can pick up an excellent signal from here. Along with about 20 or so unsecured networks. The landlord told me to use it, he installed it and used it for 4 years with no trouble. But I'm afraid for the reasons that you mentioned to use it. I just can't believe that all these people in 2009 leave their networks unsecured. Too lazy to set up the security on their routers, just plug and play.

I always use https when I'm at unsecured wireless networks, but I'm worried that someone can still see what I'm doing. I make sure the website uses AES 256 bit encryption but I don't think that's enough for encryption. Is it possible for someone to decrypt the https connection?

Nope, it's not practically possible.

Leo if your piggybacking on someone else's connection and you are on a httpS website can that info be sniffed or is it still secure?

Yep, https is point-to-point secure and safe from sniffing.

hi, my sister has a wireless internet accross the road i would say less than 100m. is it possible to connect to conect to the same internet? is there any usb that covers the range of 100m to connect to the wireless internet connection? please reply Thanks

You might get lucky with an extra antenna or something (google "wifi antenna") but as I understand it 100m is at the very fringe of what WiFi is supposed to cover in the best of circumstances.

In otherwords, I would expect the answer to be "no".

-Leo

I won't speak to the ethics, but I can certainly comment on
the RISK of using someone else's WiFi. YES, the owner of the
network you happen to be piggybacking on could monitor what
you're doing, and YES they could be doing it on purpoase.
I've certainly heard of exactly that happening - someonen
setting up a wireless access point in a public spot, and
then sniffing on whomever happens to connect.

We here a lot about the ethics of Piggybacking from one's home onto an "unsecured" network and also the safety of those who "own" the account.
But, what about those who do the Piggybacking? Is it safe for us??
If someone leaves his network unsecured could they possibly be doing it on purpose to "sniff"?

Now that I am aware of the need for httpS, can I not change my gmail account to its use?

"Definitely do not do anything that has to do with payments, money, credit cards, etc.. Just surf the net." This is nonsense propagated by those who really do not understand various types of encryption and their proper uese. As Leo said, if you have an SSL (https) connection you don't need any further encryption. And you won't have any problems with credit card transactions or banking issues, whether wired or wireless. Again, as Leo said, it's "everything else" you do on the Internet that will be easily sniffed by a hacker (even a casual one)in a wireless environment. I started using HotSpotVPN several months ago and I'm very satisfied with the results. They are the only reasonably priced VPN service that I know of that offer client based SSL type VPN that is more secure and stable than the Open VPN services that use the XP based system. And you have three levels of security to select from. Now I use hot spots anywhere with full AES encryption for ALL my Internet usage. Great peace of mind.

Earthlink's webmail system uses HTTPS all the time. Some webmail systems only use it for the login page, but not for reading and writing individual messages. Gmail will use HTTPS all the time, but only if you start out making an HTTPS request initially.

The need for safety with a wireless network is obvious. However, many people are not aware of the need for safety when plugging into a wired Ethernet connection in a hotel room. For more on that see my blog
Ethernet connections in a hotel room are not secure

Thanks Leo....that is great advice! I sent a copy to my wife, who uses her laptop more frequently these days.
With all that is 'out there' it is good to know there are proper measures that can be applied to get the technological security necessary:-)

Thanks for all you do. To log onto gmail through an https connection, I will soon be traveling on a cruise ship which will probably have a wifi connection but if not I know it has connections on its own computers. How do I use an https connection in that circumstance?
