Caution : Stay Safe on Public Wi-Fi

[DevRaj80]

This is a secure method of accessing company resources (intranet, e-mail, databases) because no matter who is also on the shared wireless network, you have a private tunnel back to your company. In some companies' VPN configurations, you can also browse the Internet in addition to accessing company resources.

Such an arrangement may be slightly slower than unencrypted Web browsing, but the security makes it worthwhile. Additionally, if you are traveling in a country that imposes Internet restrictions (such as China or Egypt), you can tunnel your traffic back through your U.S.-based VPN connection and reach sites as if you were stateside.

If your company doesn't offer a VPN service or has a "split tunneling" VPN (in which only requests to company resources travel through the encrypted tunnel, and all other traffic transmits unencrypted directly to the target), don't worry--you can still stay safe.

Try out HotSpot Shield, a no-cost VPN service from AnchorFree. The company offers its own VPN software that you install on your laptop prior to using public Wi-Fi.

Once you enable the software and service, it encrypts your traffic and sends it through a tunnel to the HotSpot Shield data center and then out to the Internet, in much the same way a company's VPN server does. HotSpot Shield even has mobile VPN settings (with no downloads necessary) to protect your Web surfing on your iPhone using the built-in Cisco VPN client software that Apple provides.

By using a such a service, you make your connection secure all the way from the coffee shop to the AnchorFree data center in Northern California. Once there, your traffic travels unencrypted to its final destination on the Internet, as if you were browsing from a laptop plugged directly into the company's data center.

This arrangement isn't perfectly secure, since the encrypted tunnel does not travel all the way to the Website you visit. However, it's certainly more secure than a setup with no VPN at all; to get in, would-be data thieves would need access to the AnchorFree data center, not just the Wi-Fi network you're on.

Wi-Fi Surfing Safety Summary

So, to recap:

1. If your company has a VPN that you can use for Web browsing, use it.

2. If you can't use a company VPN, give HotSpot Shield a try.

3. Don't equate subscription (paid-for) Wi-Fi Internet with secure browsing.

4. On unencrypted wireless networks, everyone can see where you are surfing (except on HTTPS Websites).

5. On encrypted wireless networks, everyone with the password can see where you are surfing (this could be a handful of people in your house, or hundreds of people in an airport).

6. If you must use a Wi-Fi hotspot without any form of VPN, imagine that your laptop is connected to a stadium Jumbotron. Don't visit any sites you wouldn't visit with 80,000 people looking over your shoulder.
