Wireless networking is no more a new name to computer users these days than iPod is to music lovers. This technology is one of the most popular, inexpensive and simple modes of connecting computers to the internet or a network. Both home users, work users and laptop/mobile users, who want to stay connected, even while on the move, are adopting this technology. On-the-move users are getting more inclined towards this, as they can get free wireless connections easily at most of the public paces like cafes, airports and so on. CopiaTECH is here to discuss all the threats that come with wireless connections and ways to guard against them. As a special bonus, there is a Wireless Security Buyers Guide Score Card at the end of this document. Threats for LAN Wireless Connections We all know that traditional wired internet connections are safe to use and wireless connections are more and more common. Nevertheless, before shifting to the wireless network, first look at the difference in both modes of connections. In wired networks, all your data travels through wires and is accessible to only those who are directly connected to your network or computer, while in wireless networks, all the data is transferred between your DSL, cable modem, LAN/WAN and your computer through the air in the form of radio signals. Imagine the risk to your data traveling in open air. There are risks to your data and computer with wireless connections in many ways discussed below. Piggybacking Piggybacking is the most common threat to your computer attached to a wireless internet connection, if it is not secured. In general, the range of broadcasting in indoor connection access points is 150 to 300 feet and for outdoor connections, it can extend up to as much as 1000 feet. This allows you to access your internet connection from anywhere indoors just about. But, it also allows anyone outside or close to your premises to use your internet connection without your knowledge if he or she is in the requisite range of the access point. This can be anyone nearby with a wireless enabled computer. Unsecured wireless internet connections not only invite a large number of unauthorized accesses to your internet connection but also a large number of BIG problems, like:
Page: 1 o Service violations: There may be cases when the number of internet connections to your access point crosses the limit set by your service provider. o Bandwidth shortages: The unauthorized user may use all your bandwidth for his work and hence slow down your connection o Abuse by malicious users: This is the biggest threat, as any unlawful activity done through your internet connection by the piggybacking user will end up to you on tracing. o Monitoring of your activity: The piggybacking user can easily monitor all your activities and steal your passwords and other confidential information. o Direct attack on your computer: The piggybacking user can at anytime access your computer, open your files, install spyware, adware, viruses and other malicious programs. In short, he can takeover full control of your computer without your knowledge. War Driving War driving is again a very serious threat from piggy backers. If the access point of your internet connection has such a range that it can be accessed from outside your building and even from your street, you have the risk of war driving. Sneaky computer users take advantage of this loop-hole in your connection. They drive the streets of cities with an antenna and wireless equipped computer, searching for such an unsecured wireless connection. To let you know how easy it is, an antenna can be made from a Pringles can! As they find a signal they capture details of the connection and publish them on internet. Just Google 'war driving' and be ready to be amazed and frightened. Now your unsecured connection details are available to all war drivers who may park their car in your street and use your internet connection for all kinds of i... [download for more]
