Good Intranet System Architecture

The following illustration shows Good Intranet Server and Good Intranet handheld software integrated with your overall Good Messaging network.

Good Intranet Server

Good Intranet Server is built with Java Server technology. It includes:

• Good Intranet Server Console

The server includes an HTTP-based management interface for server administration. You can access the console interface from any host on your network that runs Internet Explorer or from a Good Intranet handheld (if you have the appropriate access permissions).

• Push Management

The server includes a Push Management system to submit, cancel, and determine the status of pushed messages.

• Wireless Network Subsystem

This server subsystem controls wireless transmissions between the server and the handheld. This subsystem communicates with the Good Data Operations Center to ensure continuous, reliable message delivery.

• Logging Subsystem

The server supports an extensive logging facility you can use to view detailed server activity as well as troubleshoot problems that may occur.

• Application Development Tools

The server includes an intelligent XSLT transformation engine for graceful conversion of page content. You can develop your own applications to take advantage of these built-in transformations, or create transformations of your own.

Handheld Software

Good Intranet client software resides on the user handheld. It includes a rendering engine and browser interface for displaying pages and documents. Handheld software also includes a document storage system for storing and retrieving pushed documents.

Good Messaging Integration

Good Intranet is fully integrated with your existing Good Messaging installation.

• Good Intranet handheld software is bundled with Good Messaging applications. It exists as a co-resident on the same wireless handheld.
• Good Intranet Server works with your existing Good Messaging installation. Servers reside on the same corporate network, and communications are handled through the Good Operations Center.

Security Infrastructure

Leveraging the Good Messaging infrastructure, Good Intranet offers a complete, encrypted, end-to-end secure system.

First, when the handheld device is set up for the user, Good Messaging generates a unique encryption key for the user and places identical copies of the keys on the handheld and in the user's Exchange account. Good Technology uses encryption technology standards to encrypt and decrypt all synchronizing messages and data exchanged between the user's corporate account and handheld. Second, data flows between Good Intranet Server and the Operations Center over the Internet using the HTTPS protocol. HTTPS provides secure communications through corporate firewalls using SSL. In this communication scheme, the Operations Center, which is identified by its URL, can be thought of as the server and Good Intranet Server as its client in a client/server relationship over the Internet.

Wireless key update enhances the security of the overall system by updating the key automatically every 30 days from the date of handheld setup. The new key is sent to the handheld wirelessly and automatically installed. Messages that are sent before the new key are decrypted with the prior key, and all messages that follow the new key are decrypted using it.

Windows NT LAN Manager Authentication

Good Intranet Server also supports Windows NT LAN Manager (NTLM) network authentication. Good Intranet Server fulfills the NTLM authentication by retrieving the username, password, and domain and presenting the user a dialog. This is similar to basic HTTP authentication. The NTLM credentials (username, domain, password) are passed securely over Good's session security to the Good Intranet server to complete the NTLM handshake.

Refer to NTLM Authentication for more information about how to configure NTLM authentication and your Good Intranet Server.
