Is Free Public Wi-Fi Safe?
By Tara Swords
If you work remotely or travel a lot for your job, you probably take advantage of free public Wi-Fi often. Unfortunately, that probably means you’re regularly opening up your devices and your data to serious security threats. And if you’re a heavy user of cloud services, which often store your data on a remote server rather than your computer, Wi-Fi security is even more crucial.
Most people these days have password-protected networks at home, so it’s unlikely that anybody is able to snoop on your data as it passes between your device and your router. But when you’re surfing the Web via a free public Wi-Fi at a cafe, library or airport, you should be suspicious of everyone, says technology consultant Leo Notenboom of Ask-Leo.com. “It’s trivially easy for any of them to be watching your unencrypted information flying by.”
Here’s what you need to know to stay safe next time you’re surfing on a free public Wi-Fi connection.
Free Public Wi-Fi Tip No. 1: Turn on your firewall.
Free Public Wi-Fi Tip No. 2: Protect your smartphone or tablet.
How do you know when a site offers encryption? Instead of “http” at the beginning of the address, you’ll see “https.” You’ll also see a little padlock icon in your browser window, usually on the bottom right.
What else should you consider encrypting?
“That guy in the corner of Starbucks with his laptop -- do you trust him with your private data?” asks Notenboom. Follow these Wi-Fi safety tips, and you won’t ever have to ever wonder.
