Essentials of TCP/IP
RCCE students will learn TCP/IP protocol stack security from Layer 2 through Layer 7, including Ethernet, ARP, IP, TCP, UDP, DNS, HTTP, and TLS protocol analysis and security implications. RCCE students will learn to analyze network traffic at each protocol layer, identify protocol-level vulnerabilities including ARP spoofing, IP spoofing, TCP session hijacking, DNS poisoning, and TLS downgrade attacks. The course covers packet capture and analysis using Wireshark, network forensics techniques, protocol-based anomaly detection, and how deep protocol knowledge enables better firewall rule writing, IDS signature development, and network security troubleshooting. This essentials course covers the core knowledge needed to operate competently in this domain. Starting from foundational concepts, RCCE students will learn the fundamental concepts, terminology, risks, and defenses that form the foundation for all further study and professional practice. Students build a solid knowledge base that prepares them for more advanced courses and real-world security responsibilities.
