Securing Wireless Networks: Hands-On

Course: 420   Type: Hands-On   Duration: 4 Days
Quick Enrol  

You Will Learn How To

  • Secure wireless networks against threats and attacks
  • Implement the WPA2 and 802.11i security standards to protect your Wi-Fi network
  • Encrypt your wireless traffic using Temporal Key Integrity Protocol (TKIP) or Advanced Encryption Standard (AES)
  • Leverage 802.1X and EAP authentication within an enterprise WLAN
  • Build Wi-Fi auditing and accounting infrastructures
  • Deploy wireless intrusion detection systems (WIDS)

Course Benefits
In this course, you gain the skills to defend against attacks and maintain security within your wireless network. You learn to detect weakness in your existing network and design and configure a cost-effective security solution.

Who Should Attend
This course is valuable for anyone who manages, operates, audits or implements secure networks. Knowledge of wireless technology at the level of Course 371, "Implementing and Troubleshooting Wi-Fi Networks", is helpful.

Hands-on Training
In this course, you gain extensive hands-on experience securing a wireless network. Exercises include:
  • Discovering and sniffing WLANs
  • Decoding and analysing 802.11 frames
  • Cracking WEP and WPA2 PSK keys
  • Configuring WPA2 on APs and clients
  • Setting up 802.1X authentication
  • Installing and presenting digital certificates to RADIUS server
  • Comparing and contrasting EAP-TLS and PEAP
  • Roaming in a secure environment
  • Configuring a wireless IDS
