Practical 8 — DoS Demonstration using Colasoft Packet Builder

Aim
Observe packet traffic in an isolated, authorized lab to understand denial-of-service concepts.

STEPS
1. Install and launch Colasoft Packet Builder in an isolated lab.
2. Create a sample TCP packet and configure the lab adapter and destination.
3. Open Wireshark on the same lab interface and begin capture.
4. Observe packet volume and destination traffic; stop the test and capture.

Observation
A high volume of traffic can degrade availability. Review packet counts and destination behavior in Wireshark.

Safety
Do not flood real systems or public networks. Use only an isolated lab and explicit authorization. Avoid high-rate/loop settings outside a controlled instructor-supervised exercise.
