Compare Wireshark and tcpdump – My Work

Overview

In this activity, I compared two packet analyzers—tcpdump and Wireshark—to understand when to use each. I reviewed official docs and community guides, then distilled their core differences and shared capabilities into a concise table.

Scenario

As a cybersecurity analyst, I need both quick, scriptable captures and in-depth, interactive analysis tools. By mapping out CLI vs GUI workflows, resource footprints, and filtering options, I can choose the right tool for any investigation.

Work Done

tcpdump	Wireshark
Command-line interface for live capture Lightweight & ideal for scripting Uses BPF filters directly in CLI Saves pcap for later analysis	Graphical UI with color-coded protocols Advanced tools: stream follow, expert info Built-in filter builder and statistics Deeper packet-layer decoding
Similarities
Open-source and free to use Capture and read pcap files Support BPF-style display filters

Conclusion

My comparison shows that tcpdump excels for quick, automated captures in resource-constrained environments, while Wireshark is best for deep dives via its rich GUI. Together, they give me a complete toolkit for any packet-analysis task.
