TCP/IP Hardening Clinic: Fast Track
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 hands-on hardening course focuses on reducing attack surface through practical configuration changes and security guardrails. Starting from foundational concepts, RCCE students will learn to apply hardening baselines, validate configurations, and measure the security improvement achieved. Students walk away with actionable hardening checklists and the skills to maintain hardened configurations as environments evolve.
