Descriptions
Understanding Cybersecurity part 3 – TCP/IP and beyond!, This is the third course in a five-part series on network communication, which includes the following modules: Networks Fundamentals, The power of Wireshark, TCP/IP and beyond!, Network Communication Programming with Python, and Cyber Attack Analysis. Together, these courses provide a comprehensive foundation in networking, combining theoretical knowledge with hands-on skills for analyzing, building, and defending networked systems. This “Understanding cybersecurity” series is designed for students who wish to develop a deep and practical understanding of how modern networks operate, how data flows across systems, and how vulnerabilities in these networks can be detected and mitigated.
This third course, Understanding Cybersecurity part 3 – TCP/IP and beyond!, provides a solid foundation and know-how across the most important protocols of the network: Internet Protocol (IP), Transmission Control Protocol (TCP), and various application-level protocols. It covers IP addressing and subnetting, message fragmentation and routing concepts, as well as ICMP (Internet Control Message Protocol) messages for diagnostics and error reporting. The course details both connection-oriented (TCP-based) and connectionless (UDP-based) application protocols, emphasizing their differences in reliability, flow control, congestion handling, and supporting use cases, including HTTP/HTTPS, DNS, and DHCP. You will examine how these protocols use symmetric and asymmetric encryption and operate over UDP and TCP to enable modern Internet communication. Building on the foundation from the first and second courses, students will use Wireshark extensively to capture and dissect IP, TCP, and application-level packets, interpret sequence and acknowledgment numbers, analyze TCP’s three-way handshake, and understand connection teardown. Special attention is given to TCP reliability mechanisms such as retransmissions, flow control, and congestion control, along with common TCP and IP-based attack vectors, including spoofing, scanning, and denial-of-service (DOS) techniques. Students gain practical experience in capturing, filtering, and dissecting application-layer traffic, distinguishing normal usage patterns from anomalies, and understanding the role of each protocol in end-to-end communication. Through hands-on labs, students learn about encryption frameworks, reconstruct application-level exchanges, trace protocol handshakes, and evaluate performance or failure conditions. The course builds a strong foundation for understanding encrypted transmission, recognizing attack signatures, and testing protocol resilience, preparing for advanced topics in secure network design and intrusion prevention covered in subsequent courses of the series.
What you’ll learn
- Build an in-depth understanding of the most important layers of network communications – IP and TCP
