RTP: Audio and Video for the Internet

This chapter has outlined the features of RTP that provide privacy and confidentiality of communication, as well as authentication of participants and the media stream. It has also described various potential attacks on a system, and how they can be prevented.

These are not the only issues that a secure implementation needs to consider, though; it is also necessary to secure the session initiation and control protocols. This chapter has highlighted some issues relating to the security of these initiation and control protocols, but a full treatment of this topic is outside the scope of this book.
