Executive Summary

Security of a wireless network still ranks as one of the largest concerns of IT professionals planning to roll out an enterprise wireless LAN. Many people erroneously believe that a wireless LAN is inherently insecure. This is largely due to security flaws in early Wi-Fi protocols like WEP (Wired Equivalency Protocol), more recent vulnerabilities found in TKIP and lack of awareness as to how to deploy a secure WLAN. Today the security concerns of the legacy protocols have been largely eliminated and best practices for secure deployment have been developed allowing many wireless deployments to be arguably more secure than their wired counterparts.
