Traveling cross-country or abroad this Summer? While you're able to easily find free WiFi in airports these days, you shouldn't just hop on the first free and available WiFi signal you can find and start browsing, shopping, or logging in to secure websites.Just as leaving your home network open and unprotected with a password can be dangerous, so is piggybacking on an unsecured WiFi signal in a public area. Hackers can create fake networks in hopes of stealing your personal information. Usually (and most often), these networks are labeled to the tune of "Free Public Wi-Fi," and can be dangerous if used. Check with the airport customer service desk to find proper log-in instructions for its official wireless network. Even if you have to pay a fee to use it, it's probably worth it considering the risk you'll take by using an alternative and free unsecured network!
