What are the risks involved in using free wireless networks?

Answer 1

If you have hardended your own computer's defenses and use SSL, SSH, and VPN solutions for work then it can be okay. Remember that you should turn up your firewall to block local area network connections. A free wireless network should not be trusted.

Answer 2

Well, with wireless connections, you are transmitting information to and from the Internet. Anyone with the right equipment can capture the transmission, stealing your user ids and passwords. To secure the transmission, many people have started using virtual private networks (VPN). VPN's encrypt your transmission making it difficult for anyone to steal your user id and passwords.

Nefarious Wi-Fi opportunists can set up pirate SSID names similar to what you expect to receive from the Wi-Fi router, such as 'wayport' or 't-mobile', and then capture your private data.

Outfox the would-be thieves by encrypting your data and e-mail, and by using a virtual private network (VPN). Many employers provide VPNs to their mobile workers, so check with your IT manager first. Casual hotspot users can opt for a paid VPN service such as Boingo's Personal VPN (free trial with hotspot subscription, $30 to keep) or WiTopia personalVPN ($40 a year); both are simple to install and use. Microsoft is beta-testing its new Windows Live WiFi Suite, which will include VPN service. Pricing is not yet set...[read the rest of the article].

Answer 3

If you get onto a network that does not have any security (you don't have to enter a password to log onto it) than it is possible for someone else on the network to be able to enter into your computer. Chances are this will not happen, but it is possible.

What you do on free internet can be viewed and people can send you viruses.
