I am using NetSim, and it has an inbuilt SYN-Flood attack project. Our team would like to create other kinds of attacks i.e UDP attack, ICMP Flood, HTTP Flood etc. How do we go about doing this in NetSim?
The SYN-Flood attack project involves modifications to the TCP protocol source codes. ICMP flooding can be implemented without code modification, by triggering ICMP ping messages from a specific source to a destination via command line. UDP/HTTP flood attacks can be implemented through code changes to the application layer source code. Just need to generate UDP-based flood traffic and HTTP request floods respectively. In a similar way, other attacks can also be implemented in NetSim.
You could also do as explained in https://support.tetcos.com/support/solutions/articles/14000130254-how-to-perform-slowhttptest-dos-attack-through-netsim-emulator-. Don't need any code change for that.
