A Secure 3-Tier
File Transfer Architecture

If you are using Microsoft technologies, a base level of network security has always been difficult to achieve. Microsoft's Internet solutions, such as ISAPI, ASP, and ASP.NET, support only a vulnerable 2-tier, client-to-Web server architecture.

This 2-tier architecture presents serious security problems when a Web site has to support any type of file upload or download. How can a Web server be used to share documents when there is no secure location to store those documents? Even if a site only supports the downloading of files, imagine the impact on an organization if a Web server were compromised and files were replaced with malicious files.

Now, FileUp Enterprise Edition (FileUpEE) allows you to securely share sensitive documents by bringing a 3-tier Web site architecture to ASP and ASP.NET. FileUpEE’s 3-tier file transfer technology allows you to put a firewall between your Web server layer and your file server layer. This decouples your file storage from your Web server layer while maintaining full file availability.

FileUpEE completes file transfers between the Web server and file server over HTTP or HTTPS which means that:

• Web server-to-file server transfers can occur over any single port you choose to open on the firewall or over port 80 by default
• File transfers can be protected with SSL encryption between the client, Web server and file server
• A content-filtering firewall between the Web server and file server layers can restrict traffic to only FileUpEE requests
