RADIUS is the Remote Access Dial-In User Service, an Authorization, Authentication, 
and Accounting (AAA) client-server protocol for when a AAA dial-up client logs in or out 
of a Network Access Server. Typically, a RADIUS server is used by Internet Service 
Providers (ISP) to performs AAA tasks. AAA phases are described as follows:

●     

Authentication phase: Verifies a user name and password against a local 
database. After the credentials are verified, the authorization process begins.

●     

Authorization phase: Determines whether a request will be allowed access to a 
resource. An IP address is assigned for the Dial-Up client.

●     

Accounting phase: Collects information on resource usage for the purpose of 
trend analysis, auditing, session time billing, or cost allocation.

Wi-Fi Protected Access (WPA) is a security enhancement that strongly increases the 
level of data protection and access control to a WLAN. WPA mode enforces 802.1x 
authentication and key-exchange and only works with 

strengthen data encryption, WPA utilizes its Temporal Key Integrity Protocol (TKIP). 
TKIP provides important data encryption enhancements that include a per-packet key 
mixing function, a message integrity check (MIC) named Michael an extended 
initialization vector (IV) with sequencing rules, and a also re-keying mechanism. Using 
these improvement enhancements, TKIP protects against WEP's known weaknesses.

PEAP is a new Extensible Authentication Protocol (EAP) IEEE 802.1x authentication 
type designed to take advantage of server-side EAP-Transport Layer Security (EAP-TLS) 
and to support various authentication methods, including user's passwords and one-time 
passwords, and Generic Token Cards.
