Assigning a Certificate to your Web Server for HTTPS (Windows Embedded Standard 2009)
To protect the communication between your device and your Web server as it downloads updates, it is recommended that you configure DUA to use Secure HTTP (HTTPS). HTTPS requires client authentication and 128-bit encryption.
