Project Squared Update: Secure Media

- December 18, 2014 - 0 Comments

The cloud is software in motion.

Our recently announced Cisco Collaboration Cloud did not stop moving once we launched it on November 17. We’ve been pushing code into the cloud multiple times per day and have release several client updates since we launched. The great thing about this model is that we can be delivering new features constantly without waiting for a giant release. This also means that, when a feature doesn’t get done by a particular date, it’s not the end of the world. It doesn’t need to wait for a huge release 6-12 months later. It might come just a few weeks later.

This is exactly what has happened with an important security feature which we didn’t quite finish in time for Collaboration Summit – secure media (also known as Secure RTP or SRTP). The version of the application that we launched on November 17 did not utilize secure media in all clients. Given our focus on security this was obviously something we weren’t happy about. But, we knew that it was almost done and we would push it soon enough.

I’m pleased to report that we have indeed pushed secure media. All of our Project Squared clients – the Mac, Android, IOS and web clients send all media in encrypted form to our media servers. The media is secured using a flavor of SRTP known as DTLS-SRTP, which performs the key exchange inline with the media itself.  SRTP is on by default and cannot be disabled. This is consistent with our general approach to security – to make it always there but invisible to end users. Neither our users nor our admins of the collaboration cloud need to do anything to make sure media is secure. It just is.

Of course – we’re not done yet! There is still a healthy backlog of features, including many more great security improvements, that we’re working on. Stay tuned, more stuff is  coming. That’s because the cloud is software in motion.
