CS402: Computer Communications and Networks

Watch this video up to 14:25 to learn about the vulnerabilities in the Real-Time Transport Protocol (RTP) used for streaming audio and video content over IP networks. Knowledge of RTP's architecture and the significance of using randomized sequence numbers and timestamps to improve security. The video gives a hands-on demonstration of a critical vulnerability within the Asterisk PBX system, where RTP sessions can be hijacked by packets with incorrect source information. This points out the need for packet validation in RTP implementations to prevent unauthorized access and to ensure secure communication.
