The presence of wireless networks in domestic settings is rapidly growing. However, many home owners are unaware of the potential security risks that are involved with using wireless LANs. Because this technology is new to many people, when they purchase a network set-up pack they are reluctant to change the factory settings (Ward, 2002). Home users are also used to the dial-up aspect, which seemed more secure and more difficult for hackers to penetrate. Now, many people simply take the devices out of the box, plug them in and leave them. However, as a result of this negligence there is a significant risk that they could be broadcasting sensitive information (i.e. credit card numbers) to anyone who is interested.
The security issue of wireless networks first arose in the corporate sector when many companies had just begun to use wireless networking systems. Unknowingly they were transmitting important and confidential information to outsiders. Most wireless networks are encrypted with codes that keep the information safe (Tuesday, 2004). However, hackers have found ways to break these codes and access company documents.
However, it is not only enterprise networks that are suffering. The main victims are home users. Because of lack of knowledge and a false sense of security, it is easy for hackers to invade at anytime and leave unnoticed. But in most cases it is already too late.
Because of the rapid growth of popularity of wireless networks, users can purchase inexpensive equipment and be totally oblivious to the security risk. But making it easier for hackers to access personal information is in no way the only risk. Individuals who steal music or upload pornography can now borrow another person’s network (Brodsky, 2004). This can lead to innocent people being prosecuted. Also, a growing number of laptop computers support WiFi. These devices, if connected to wire networks could be broadcasting data and thus provide back-door-access if the wireless networking mode is inadvertently left running.
In light of the mounting security threats, many software companies are trying to address the issue. Wireless network uses are encouraged to use security software and update virus protection regularly.
