TCP/IP Troubleshooting
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 diagnostic course focuses on identifying, analyzing, and resolving common failures, misconfigurations, and operational issues. Building on core knowledge, RCCE students will learn systematic troubleshooting methodologies that accelerate root-cause analysis and minimize downtime. Students work through realistic break-fix scenarios that build the diagnostic confidence needed for high-pressure production environments.
