Compromised and Degraded Network Simulation

The aim of the dissertation was:

"Create a custom simulated network that can demonstrate and visualise network degradation and common DoS attacks, so that network engineers can identify weak spots and points of strain"

Report Download

TODO - Compile report and link here

Repository Layout

Project code for the project:

• /PacketCapture - Contains the script that perfoms different degradation effects on a network connection
• /ClientServer - Contains the programs used in the test network
• /Report - Write up for the project
