PCWorld: How To Stay Safe At Wi-Fi Hotspots
Describes the risks involved in using public Wi-Fi hotspots and what you can do to counteract them, including turning off Wi-Fi and Bluetooth when you’re not using them.
“Wi-Fi is everywhere. Whether you travel for business or simply need Internet access while out and about, your options are plentiful. You can sign on at airports, hotels, coffee shops, fast food restaurants, and now, airplanes. What are your risk factors when accessing wireless? There are plenty. Wi-Fi wasn’t born to be secure. It was born to be convenient. Wireless networks broadcast messages using radio and are thus more susceptible to eavesdropping than wired networks.
Anyone using an open unsecured network risks exposing their data. There are many ways to see who’s connected on a wireless connection, and to gain access to their information. As more sensitive data has been wirelessly transmitted over the years, the need for security has evolved. Today, with criminal hackers as sophisticated as they ever have been, wireless communications are at an even higher risk.”
