Ever wondered how to ace the CISSP Cyber exam's domain four? Or, perhaps, you're merely intrigued by the intricate world of Voiceover IP (VOIP)? Either way, this episode is packed with the insights you've been seeking! Join me, Sean Gerber, as we dissect the key protocols that VOIP uses for multimedia transmissions. Together, we'll unravel the complex intricacies of Session Initiation Protocol (SIP) messages and how sessions kick off in a VOIP implementation. You'll also gain an understanding of the differences between Real-Time Transport Protocol (RTP) and Real-Time Transport Control Protocol (RTCP) and how they're applied. As we journey deeper into this episode, we'll explore the fascinating world of Internet Small Computer Systems Interface (iSCSI), focusing on its functions and default ports. Fear not, the mystery of SCSI command encapsulation will no longer be a mystery to you! We'll then shift our attention to the security aspects of SIP-based VOIP traffic, scrutinizing SIP-aware firewalls and the implementation of Transport Layer Security (TLS). Finally, we'll round off our discussion by examining RTCP's role in providing quality of service feedback in a VOIP implementation and wrapping up with an understanding of block-level transport in iSCSI.
