AG 310020 IntroductionSecure Socket Layer (SSL)This feature allows for the creation of an end-to-end encrypted link between your NSE-powered product and wireless clients by enabling the Internal Web Server (IWS) to displaypages under a secure link—important when transmitting AAA information in a wirelessnetwork when using RADIUS.SSL requires service providers to obtain digital certificates from VeriSign™ to create HTTPSpages. Instructions for obtaining certificates are provided by Nomadix.Secure XML APIXML (eXtensible Markup Language) is used by the subscriber management module for useradministration. The XML interface allows the NSE to accept and process XML commandsfrom an external source. XML commands are sent over the network to your NSE-poweredproduct which executes the commands, and returns data to the system that initiated thecommand request. XML enables solution providers to customize and enhance their productinstallations.This feature allows the operator to use Nomadix' popular XML API using the built-in SSLcertificate functionality in the NSE so that parameters passed between the Gateway and thecentralized Web server are secured via SSL.Session Rate Limiting (SRL)Session Rate Limiting (SRL) significantly reduces the risk of “Denial of Service” attacks byallowing administrators to limit the number sessions any one user can take over a given timeperiod and, if necessary, then block malicious users.Session Termination RedirectOnce connected to the Public access network, the NSE will automatically direct the customerto a Web site for local or personalized services, or to establish an account and pay for servicesthrough its Home Page Redirect functionality. In addition, the NSE also provides pre and postauthentication redirects as well as one at session termination. See also, Home Page Redirect onpage 11.If you plan to implement XML for external billing, please contact technicalsupport for the XML specification of your product.
