This course is for Networking and Security personnel who must develop packet investigation techniques by studying the WiFi and Wireless Networking Protocols (IEEE 802.11a, b, g, n, ac, ad, az) using Wireshark and other Open-Source Analysis tools. It gives the Engineer the key WiFi / Wireless Network Analysis skills to capture the correct WiFi data and locate unusual patterns hidden within seemingly normal Wireless network traffic.

This course provides the student with a set of analysis techniques focusing on the use of vendor-neutral, Open-Source Tools to provide insight into the following areas:

– Wireless Network Analysis fundamentals using Open-Source Wireless Network Analysis Tool to analyze traffic patterns associated with Wireless network behavior

– Wireless focused network security principles, including encryption technologies and defensive configurations of network infrastructure devices

– Recognition for various issues that affect WiFi/WLAN-based networks and the quality of the data. Factors including latency, out-of-sequence packets, packet loss, and retransmissions and how the End-User experiences them are analyzed and evaluated. Key Wireless related protocols, including Data, Management, Control, and related supporting protocol architectures, are examined.

– Advanced Wireless Network Analysis techniques, including data traffic reconstruction and viewing

– Specialized Wireless-based investigative techniques for the Internet of Things (IoT) enabled devices

This course is for Networking, Government, and Security personnel that need to develop a set of Wireless-based packet investigation techniques by studying the WiFi and Wireless Networking Protocols using Wireshark and other Open-Source Analysis tools.
