Cisco LEAP (EAP Cisco Wireless) is a server and client 802.1x authentication via a user-
supplied logon password. When a wireless access point communicates with a Cisco 
LEAP-enabled RADIUS (Cisco Secure Access Control Server (ACS) server), Cisco 
LEAP provides access control through mutual authentication between client wireless 
adapters and the wireless network and provides dynamic, individual user encryption keys 
to help protect the privacy of transmitted data. 

The Cisco Rogue AP feature provides security protection from an introduction of a rogue 
access point that could mimic a legitimate access point on a network in order to extract 
information about user credentials and authentication protocols which could compromise 
security. This feature only works with Cisco's LEAP authentication. Standard 802.11 
technology does not protect a network from the introduction of a rogue access point. 

Cisco Key Integrity Protocol (CKIP) is Cisco proprietary security protocol for encryption
in 802.11 media. CKIP uses the following features to improve 802.11 security in 
infrastructure
mode:

●     

Key Permutation

●     

Message Integrity Check

●     

Message Sequence Number
