Only a small percentage of public networks prevent wireless eavesdropping, and many networks leave wifi users completely responsible for their laptop security, with extensive or complete file and service exposure. Wireless eavesdropping is possible everywhere. It is literally impossible to tell the safe networks from the bad ones.

You may assume you are safe from outside attacks, but you really have no idea whether any firewall lies between your laptop data and the Internet.īusiness travelers willing to connect to any network that offers free Internet access are especially vulnerable to such attacks. This is not necessarily true in public wireless networks, where security practices vary widely.
Most private networks use firewalls to defend users against Internet-based attacks. But the risks of using WiFi networks at a hotel or airport are exponentially greater than those experienced at home or in an enterprise setting.įor example, while sharing folders, printers, desktops, and other services can be useful at home or in the office, doing so is inappropriate on a public network, where competitors or hackers can access this information. Many of us assume that using a WiFi network at a hotel or airport is the same as logging into our network at home or at the office. You have a vague sense that you might not be doing something safe, but you figure that you’re only going to be online for fifteen minutes, so you’re probably okay, right? You login to your banking account to transfer funds. You are waiting to catch your flight in an airport and, after grabbing a cup of coffee and opening your laptop, you see that there’s a “Free Public WiFi” network available.For just a second, you have a fleeting thought: “Is my computer at risk?” And then you begin your normal Internet activities and quickly forget all about it. You are on vacation and you open your laptop in your hotel room. You log into the public WiFi network, and quickly agree to the Terms and Conditions (without reading them of course), and start to do your normal Internet activities.
