AG 5500
18 Introduction
Secure 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 display
pages under a secure link—important when transmitting AAA information in a wireless
network when using RADIUS.
SSL requires service providers to obtain digital certificates from VeriSign™ to create HTTPS
pages. Instructions for obtaining certificates are provided by Nomadix.
Secure XML API
XML (eXtensible Markup Language) is used by the subscriber management module for user
administration. The XML interface allows the NSE to accept and process XML commands
from an external source. XML commands are sent over the network to your NSE-powered
product which executes the commands, and returns data to the system that initiated the
command request. XML enables solution providers to customize and enhance their product
installations.
This feature allows the operator to use Nomadix' popular XML API using the built-in SSL
certificate functionality in the NSE so that parameters passed between the Gateway and the
centralized Web server are secured via SSL.
Session Rate Limiting (SRL)
Session Rate Limiting (SRL) significantly reduces the risk of “Denial of Service” attacks by
allowing administrators to limit the number sessions any one user can take over a given time
period and, if necessary, then block malicious users.
Session Termination Redirect
Once connected to the Public access network, the NSE will automatically direct the customer
to a Web site for local or personalized services, or to establish an account and pay for services
through its Home Page Redirect functionality. In addition, the NSE also provides pre and post
authentication redirects as well as one at session termination. See also,
“Home Page Redirect”
on page 10 .
If you plan to implement XML for external billing, please contact technical
support for the XML specification of your product. Refer to
“Contact
Information” on page 305 .
