                        Overview
                        

                            
This course introduces students to 802.11 wireless local area networks (WLAN) and the application of analytical techniques on captured wireless network traffic. The course will begin with an introduction to radio frequency (RF) fundamentals, components, and signaling as it relates to 802.11 wireless local area networks (WLAN). Students will understand how wireless networking integrates into more traditional wired networks through various wireless network hardware. Students will learn how devices operate and contend for the wireless medium. An emphasis is placed on wireless vulnerabilities, mitigating weakness in security, and how encryption algorithms are used. Students will get hands-on exercises using open source network capture tools and protocol analyzers and apply them to examine captured data.  Students will learn how site surveys are used to optimize wireless networks. The final topics focus on wireless threats and the examination of common attacks.
