Many cafés, hotels, airports and other public establishments offer wireless networks for their customers' use. These "hot spots" are convenient, but they may not be secure. Ask the proprietor what security measures are in place.
Increasingly, computer users interested in convenience and mobility are accessing the Internet wirelessly. Today, business travelers use wireless laptops to stay in touch with the home office; vacationers beam snapshots to friends while still on holiday; and shoppers place orders from the comfort of their couches. A wireless network can connect computers in different parts of your home or business without a tangle of cords and enable you to work on a laptop anywhere within the network's range.
The downside of a wireless network is that, unless you take certain precautions, anyone with a wireless-ready computer can use your network. That means your neighbors, or even hackers lurking nearby, could "piggyback" on your network, or even access the information on your computer. And if an unauthorized person uses your network to commit a crime or send spam, the activity can be traced back to your account.
Fortunately, there are steps you can take to protect your wireless network and the computers on it. As no one step is a complete fix, taking all of the following steps outlined by OnGuard Online will help you be more secure.
