3.3.3 Security
Here users define the security type and level of the wireless network. Selecting different methods
provides different levels of security. Please note that using any encryption may cause a
significant degradation of data throughput on the wireless link. There are five Encryption
types supported: “None”, “WEP”, “WPA (TKIP)”, ”WPA2(AES)”, and “WPA2 Mixed”.
 No Encryption Used
 Encryption: “None” means no encryption used. Users can enable 802.1x
Authentication and enter the RADIUS server parameters – port, IP address and
Password.
 Use 802.1x Authentication: Is a port access protocol for protecting networks via
authentication. If wireless user is authenticated (via 802.1x), a virtual port is
opened on the router/access point allowing for communication. If authentication
fails, the router/access point will deny access to the user.
 Authentication RADIUS Server: RADIUS is the Remote Access Dial-In User
Service, an Authorization, Authentication, and Accounting (AAA) client-server
protocol, which is used 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 perform 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 is 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.
Users must enter RADIUS Server’s Port number, IP address and Password.
