The application sets up a window on the browser through which the user can link up to the mainframe via Cyberprise Host TN3270E emulation to access and manipulate IMS screens of data. We need to understand the risks better. The VPN link creates a secure, reliable intranet that external and internal customers can use to download the client application and access the mainframe, Wadman says. Data doesn't mean as much if you can't manipulate it. The user is given an internal uniform resource locator to a Web page on the server from which he can download the Host On-Demand Java applet to the browser.
Security is handled by authenticating at the point where the user dials in to the network.
When the host session is established, the user also authenticates with the host. It resumed its search about three months ago, tested the available products and chose Host On-Demand, then in beta. It then waited for general availability, retested the product within a limited group of physicians and is finishing the rollout this month. Physicians also needed to be able to establish 3270 print sessions that output to their local printer. ENetwork Communications Server provides that through its TN3270E support.
