Course Outline

WP-202 Advanced WLAN Assessment and Analysis ("Packets Never Lie")

Duration
Public Class Duration: 3 Days (prerequisite of WP-200 STRONGLY recommended)
Web-Delivered Class Duration: 4 half days (9:30 AM PT - 12:00 PM PT M-TH)

Prerequisite: WP-200 STRONGLY recommended

Overview and Method
This course dives deeper into wireless protocol analysis, particularly a more thorough understanding of wireless management, security, TCP/IP and related protocol variants, both benevolent and nefarious. It builds on the troubleshooting concepts in WP-200 to include long-term statistics gathering, monitoring, and general wireless network health. In-class activities are more advanced, often combining concepts in more complex scenarios for students to decipher. Successful graduates from this class will be ready to immediately apply skills in real-world environments.
