|Project Description: ||Wireless networking allows for a great sense of freedom for all computer users. Entities taking advantage of this technology include everyone from home users building personal networks to large scale business enterprises. Previous methods of securing communications in a wired network are not always applicable in a wireless environment, primarily due to the absence of the physical medium and the open characteristic of communication. The report examines one of the techniques currently deployed to secure wireless networks, specifically, MAC address filtering. The program written illustrates how this technique may be circumvented by making use of the packet capture library available on freely on the Internet. The program is run on a laptop with a wireless interface and is able to obtain the hardware addresses of nodes in surrounding networks. To test the program, a wireless network is established using the typical equipment used in a home or small offices.
