Asp – How to set the IIS File Security to Integrated Windows authentication with a Web Setup Project installer

I wrote an ASP.NET web application with an installer. For the installer, I'm using the Web Setup Project under the Setup and Deployment project types in Visual Studio 2008.

How do I set the IIS File Security to Integrated Windows Authentication on only one .aspx page or directory during the installation process using a Web Setup Project? If it is not possible with the Web Setup Project how would I automate that task?

Currently I'm installing the application with the installer and manually setting the security permissions.
