Cisco IUWNE 1.0: WLAN Security Basics

This course is included in our On-demand training solution.


Early security for wireless communication was weak, as the IEEE 802.11 standard was designed for ease of deployment in residential homes instead of in enterprise environments. With the widespread adoption of wireless networks by businesses, better protection of data and the ability to authenticate users was required. Thanks to improvements in security protocols, today’s wireless networks are as secure, if not more secure, than wired networks. This course provides an overview of WLAN security and shows the steps required to ensure privacy in wireless networks as well as some of the advanced features that Cisco networks have to increase wireless network security. This course also explains the configuration of basic WLAN security and describes centralized WLAN authentication.
This course maps to the 640-721, Implementing Cisco Unified Wireless Networking Essentials (IUWNE), exam objectives for describing 802.11 authentication and encryption methods including Open, Shared, 802.1X, EAP, TKIP, AES, LEAP, PEAP, AES, WPA/WPA2, TKIP, PSK, EAP-local or -external, and RADIUS.

Target Audience
