The IIS 10.0 website document directory must be in a separate partition from the IIS 10.0 websites system files.

The content database is accessed by multiple anonymous users when the web server is in production. By locating the content database on the same partition as the web server system file, the risk for unauthorized access to these protected files is increased. Additionally, having the content database path on the same drive as the system folders also increases the potential for a drive space exhaustion attack.

Note: If this server is hosting WSUS, this requirement is not applicable. Note: If this IIS 10.0 installation is supporting Microsoft Exchange, and not otherwise hosting any content, this requirement is not applicable. Note: If this server is hosting the SharePoint Web Services site, this requirement is not applicable. Note: If the server is hosting Office Online Server (OOS), this is Not Applicable.
