How to secure access to private network files via IIS 6.0?

["Sistemas Aurensis-Sys Sec" <syssec () aurensis com>]

If files are static or change for example every day I prefer not open ports in the PIX firewall and upload this files 
with sftp. Open ports always have a risk, hackers have more points to try and more points to find a hole.
If you have one possibility for not open ports its better.
Ports 139 and 445 invoke try to hack.

Asunto: How to secure access to private network files via IIS 6.0?




I am looking for some info on best practices for securing file access to internet users via IIS 6.0.  We have document 
files that are accessible via our private internal Windows servers, but there is a need to have some of them available 
for internet users.



Our web server (Windows 2003 Server IIS6.0) is currently in a DMZ behind a PIX firewall. How can we provide 
authentication and access to files on the private network via our web server without having to host a seperate copy of 
those files in the DMZ? If we open up ports 139 or 445 for the web server in the DMZ to enter the inside, wouldn't we 
be putting our inside environment at a larger risk in the event someone hacks our web server?  What are best practices 
for this type of need?
