Training description:
Almost every attack, intrusion, scan, and exfiltration involves the TCP protocol at some point. Whether we are hacking a system and need to better understand how networks/systems are enumerated and IDS’s do their thing, or we are defending our domain from a botnet attack, a deep understanding of the TCP protocol will help us do our jobs better and faster. In this course, get ready to go deep into TCP. We’re going to rip open pcaps with Wireshark and learn how this protocol really works. Don’t worry, there is FAR more to learn past the three-way handshake! We will learn how the MSS works, receive windows, selective acknowledgements, retransmissions, and much, much more! We will examine how TCP scan, OS enumeration, exfiltration, and C2 traffic looks on the wire, and how TCP fields can help us to filter for it fast. This will be an action-packed, hands-on course for Wireshark beginners as well as seasoned pros who want to pick up some new tricks. There is something for all experience levels in this course, although it will be targeted to the early-intermediate cybersecurity professional.
