Traffic Analysis of IEEE 802.11 on Physical Layer by using Software Defined Radio

The security of wireless networks is a fairly discussed topic. There are many threads capable of attacking any personal, public, or company network. One way of protection is to analyze traffic on the desired wireless network and look for irregularities in the traffic. There are various approaches on how to capture and analyze wireless traffic. In this paper, we present three enablers on capturing wireless traffic, including Off-the-shelf wireless cards and software defined radios. The results provide the capabilities of used devices and possibilities on how to analyze the traffic. We also present our developed wireless traffic visualizer written in python that can be utilized to discover possible attacks on wireless networks visually.
