Title

The IIS 8.5 website document directory must be in a separate partition from the IIS 8.5 websites system files. (Cat II impact)

Discussion

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