Episode 28 — Map OSI TCP IP IPv4 IPv6 and VPN Concepts Clearly

This episode explains the networking foundations that cybersecurity professionals must understand in order to interpret traffic, communicate clearly, and make better control decisions. For the exam, you are expected to know the purpose of the OSI and TCP/IP models, recognize the role of addressing in IPv4 and IPv6, and understand how virtual private networks protect traffic across less trusted networks. We will connect these ideas through examples such as routing between segments, encrypted remote access, protocol troubleshooting, and address exhaustion, so you can see how layered models, network communication, and secure transport support both practical security analysis and accurate answers when questions combine networking with access, monitoring, or remote connectivity.
