The document discusses authentication and encryption for wireless networks. It states that open authentication provides no user authentication while WEP provides weak authentication and encryption. It recommends using a central server and individually authenticating each user for stronger authentication. WPA and WPA2 create a framework for stronger authentication and encryption, and Cisco Centralized Key Management can be added to increase roaming efficiency. Most security features can be configured on the controller and EAP types will be relayed while the controller uses encryption angle to categorize the security type.

1. Module Summary Authentication proves the user or device identity, while encryption protects the frame from eavesdropping. Open authentication provides no user authentication and can be used in combination with a stronger system; WEP provides authentication and encryption but is a weak protocol. A good way to enforce authentication is to use a central server and authenticate each user individually. WPA and WPA2 create the framework for a stronger authentication and encryption; Cisco Centralized Key Management can be added to increase roaming efficiency. Most of the available security features can be configured on the controller; most of the EAP types will simply be relayed, and the controller will use the angle of the encryption to categorize the security type.
