Though not ideal, a partial supplement in this scenario is also checking the REFERER, can thwart automated tools to a degree

I understand authentication to these documents is not an issue what is
an issue is directory listing. IIS prevents this by default so I assume
you are using Apache, Tomcat or another server. So the best way to
prevent this issue is to modify your .htaccess file to avoid listing
files:

Here is an example of how to use it

Another idea is to proxy your download URLs through a script and hide
the real files outside the web root.

If you do it in PHP it's pretty simple (header + read file + bit
security). Just make sure to make the script secure in terms of
directory transversal etc., many people hide their downloads for
security and create even bigger holes with bad scripts.
You can also add all sort of attack detection to it, like recording the
hit count of an IP to it and auto locking the downloads after a certain
amount.

Hope this helps.

A question:

Given a website URL like the below :

http://www.companywebsite.com/resources/resources/whitepapers/document
_1_wp.pdf
http://www.companywebsite.com/resources/resources/whitepapers/document
_arbinatryname__wp.pdf

How can I protect somebody from enumerating the list of file on this
"whitepapers" directory ?  What tool can I use to make sure that I am
adequately protected against this ?
Cheers
