Networking & Traffic Analysis (Completed December 2024)
Designed and configured segmented networks using VLANs, subnetting, and access controls to enhance security. Used Wireshark to analyze traffic, detect anomalies, and troubleshoot performance issues in real-world simulated environments.
Description:
Used Wireshark to capture and analyze network traffic, identify key protocols, and troubleshoot connectivity issues on a segmented home network. Applied insights to optimize network performance.
Learned:
Developed practical skills in network traffic analysis and troubleshooting.
Analyze network Traffic
TLS v1.2 traffic encrypted HTTPS traffic using TLS handshake
TCP traffic classic TCP ACK and FIN-ACK packets show connection establishment and teardown
LLMNR (Link Local Multicast Name Resolution) local Windows name resolution traffic
Home Network Traffic
QUIC traffic to IPs like Google / YouTube traffic or Chrome-based browsing.
ARP broadcast device asking "who has IP X, tell me MAC address Y"
mDNS → My device is announcing/discovering services on your LAN
NBNS query → NetBIOS name lookup
Role & Collaboration:
Outcome:
Gained hands-on experience with Wireshark, analyzing traffic and protocol behavior. Built foundational skills in network troubleshooting and interpreting common protocols like TCP, UDP, and DNS.
