Sun Java System Portal Server 7.1 Deployment Planning Guide

Security

When you use NetFile with Secure Remote Access configured for SSL, all connections made from NetFile applets to the underlying file system happen over the SSL connection established between the Gateway and the browser. Because you typically install the Gateway in a DMZ, and open a limited number of ports (usually only one) in the second firewall, you do not compromise security while providing access to the file systems.
