Background: Our client wanted to create an extranet to expose certain work order and invoice information contained in their existing custom system to their clients.
Problem: The system needed to be secure both from outside intrusion as well as only showing the proper information to the clients. Additionally, extranet users were to be able to add comments to the work orders, and a mechanism was needed to be sure that internal users would be made immediately aware of these comments when they were added.
TnK Group's Solution: Using c# and asp.net, TnK Group built a secure application to fulfill our client’s needs. To address security concerns, the extranet utilizes SSL encryption and firewall rules were employed to properly isolate the web server from the database. Asp.net security was employed to ensure that extranet users could not gain unauthorized access to any other data stored in the database.
For the comment notification portion, we added a form to the existing enterprise application to display the most recent comments, who added them and the date and time they were created. We created a separate thread in the background to update this window every minute so the latest comments will always be displayed to the users while logged in with no other interaction required.
