In this presentation, we will provide the OWASP audience the necessary insights in this emerging Web technology, and discuss the various security aspects of WebRTC. This content is based on a recent study of the Web Security specifications the author has been conducting together with researcher from W3C, IETF and SAP. Firstly, the overall WebRTC architecture will be presented, and the enabling technologies (such as STUN, TURN, ICE and DTLS-SRTP) will be introduced. This architecture will be illustrated in multiple deployment scenarios. As part of this description, the basic security characteristics of WebRTC will be identified. Secondly, we will discuss how the new WebRTC technology impacts the security model of the current Web. They will highlight some of the weaknesses they have spot during their security assessment, as well as discuss the open security challenges with the WebRTC technology.
