CISSP®- IAAA - Part 1- Identification, Authentication, Authorization, and Accountability

The video tutorial covers the OSI model, focusing on Layers 3 to 7. It explains Layer 3's role in networking, including IP and ICMP protocols, and Layer 4's transport functions with UDP and TCP. The tutorial delves into TCP's reliability and connection-oriented nature, discussing the three-way handshake and common attacks. Layers 5 to 7 are explored, highlighting their roles in session management, data presentation, and application interaction. A practical example illustrates the OSI model's application, concluding the session.
