Preventing Security Problems

The following list summarizes some of the possible ways in which security problems can be avoided:

Reading the data flow between browser and web server
SSL (secure socket layer) will prevent eavesdropping of data.
Hacking into the application server code
Router filtering will ignore all TCP/IP packets to port 6500 of the application server.
The firewall will ignore all TCP/IP packets to port 6500 of the application server coming from any other host than the web server.
Copying the URL to another browser
The basic Dynamic 4GL mechanism will reject the copied URL.

Reading the data flow between the HTML client and the HTML server
Anyone attempting to break into the system must gain control of a machine based on the secured network or on the secured service network.

Denial of service
The HTML Client is a small connectionless program that can only transmit authorized packets to the HTML server. Therefore, even if the client stops functioning, the server will still be accessible.
