Walkthrough on how to use FTP authentication to provide dynamic IP restrictions FTP 7.5

Few months back, Microsoft released a new module that blocked HTTP requests from brute force attack, http://www.iis.net/extensions/DynamicIPRestrictions   This is great for HTTP requests, but didn’t address another pressing need, FTP brute force attacks.  Robert McMurray published a walkthrough for the FTP service that shows how to create an authentication provider, that gives you dynamic IP restrictions for the FTP service.

Here is the how-to:

Thanks Robert for the great article.
