Can I use SSL to protect my signage content?

Applies to

  • Carousel 6.3.0+

Answer

SSL can be used to protect the user session into the Carousel Web UI. Player content downloads must occur over port 80, although they are checked to ensure the original file arrived without tampering.

To enable SSL on your Carousel web server, add port 443 to the bindings of the web site running Carousel. (generally the "Default Web Site") Port 80 must remain operational, as the Carousel Players use port 80 to transfer their content.

The Carousel Players compare the MD5 checksum of the files they have downloaded to the master server to ensure they match before being displayed. This helps to protect against content corruption from network errors, but can not guarantee that the files have not been tampered with by a man-in-the-middle attack.

 

Additional Information

The technical details of adding an additional port number to IIS are beyond the confines of this article and should be handled by the web server administrator.
