Packet Sniffer and Network Traffic Analyser

Approx. component budget: Rs. 0 - 500

Objective

Understand what really travels on a network and spot odd behaviour automatically.

What you will build

A tool that captures packets on your own network, decodes TCP, UDP, DNS and HTTP headers, and shows charts of protocols, top talkers and unusual spikes.

Results you can expect

• Correct decoding of at least 5 protocols compared with Wireshark
• Packets per second handled
• A detected port-scan test
• And a daily traffic summary report

What you will learn

The TCP/IP stack in practice, packet structure, sockets, and basic network monitoring.

Tools and notes

Python with Scapy or C with libpcap, Wireshark, Matplotlib. Capture traffic only on your own network or lab setup.

Resume points from this project

• Built and tested Packet Sniffer and Network Traffic Analyser; objective: understand what really travels on a network and spot odd behaviour automatically.
• Measured and analysed correct decoding of at least 5 protocols compared with Wireshark and packets per second handled; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
