Security Overview
This section describes the types of security features you can enable on the access
point. The security features protect wireless communication between the access
point and other wireless devices, control access to your network, and prevent
unauthorized entry to the access point management system.
Levels of Security
Security is vital for any wireless network, and you should enable all the security
features available on your network. Figure 4-1 shows possible levels of security
on Cisco Aironet wireless networking equipment, from no security on the left to
highest security on the right. The highest level of security, EAP authentication,
interacts with a Remote Authentication Dial-In User Service (RADIUS) server on
your network to provide authentication service for wireless client devices.
