3.3.3 SecurityHere users define the security type and level of the wireless network. Selecting different methodsprovides different levels of security. Please note that using any encryption may cause asignificant degradation of data throughput on the wireless link. There are five Encryptiontypes supported: “None”, “WEP”, “WPA (TKIP)”, ”WPA2(AES)”, and “WPA2 Mixed”.No Encryption Used Encryption: “None” means no encryption used. Users can enable 802.1xAuthentication and enter the RADIUS server parameters – port, IP address andPassword. Use 802.1x Authentication: Is a port access protocol for protecting networks viaauthentication. If wireless user is authenticated (via 802.1x), a virtual port isopened on the router/access point allowing for communication. If authenticationfails, the router/access point will deny access to the user. Authentication RADIUS Server: RADIUS is the Remote Access Dial-In UserService, an Authorization, Authentication, and Accounting (AAA) client -serverprotocol, which is used when a AAA dial-up client logs in or out of a NetworkAccess 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 localdatabase. After the credentials are verified, the authorization processbegins. Authorization phase: Determines whether a request is allowed access to aresource. An IP address is assigned for the Dial-Up client. Accounting phase: Collects information on resource usage for the purposeof trend analysis, auditing, session time billing, or cost allocation.Users must enter RADIUS Server’s Port number, IP address and Password.
