Web based integrated customer interface for invoice reporting

A double firewalled system is disclosed for protecting remote enterprise servers that provide communication services to telecommunication network customers from unauthorized third parties. A first router directs all connection requests to one or more secure web servers, which may utilize a load balancer to efficiently distribute the session connection load among a high number of authorized client users. On the network side of the web servers, a second router directs all connection requests to a dispatcher server, which routes application server calls to a proxy server for the application requested. A plurality of data security protocols are also employed. The protocols provide for an identification of the user, and an authentication of the user to ensure the user is who he/she claims to be and a determination of entitlements that the user may avail themselves of within the enterprise system.
