OBJECTIVES

By the end of this course delegates will be know;

  • Radio frequency properties, behaviors, and regulations, and how they affect networking
  • Wireless standards, including 802.11 extensions a, b, g, and n
  • General troubleshooting tips to common real-world 802.11a/b/g issues
  • General parameters for performing a successful site survey, along with software tools that reduce time and expense
  • Device-level Wi-Fi communications processes
  • Why 802.11a/b/g networks operate the way they do and how to apply that knowledge when faced with problems that stump most network administrators
  • Using wireless network analyzers to capture live data and pinpoint potential network issues
  • How using radio frequency makes wireless networks vulnerable
  • The most common wireless threats and how to detect and defend against them
  • Wireless security standards for keeping unauthorized users out and maintaining wireless data privacy
  • The application of 802.11i/WPA2 standards, including 802.1X/EAP, and the devices used to apply them
  • Wireless intrusion detection and why it's essential for maintaining a secure network
