Protecting OTT services: Why multi-DRM is no longer enough

While multi-DRM provides a basic level of protection for OTT streaming services, it should be considered as a baseline from which to build. It addresses the content security threat but the service itself remains vulnerable, and the surface area for pirates to attack is considerably greater in streaming than in traditional broadcast. What is needed is a comprehensive security strategy that includes watermarking, a way to deal with credential sharing, and anti-piracy services that identify leaks and prompt actions ranging from takedowns to device advisory messages. The risks from increased virtualisation should also be addressed.
