Is there any kind of firewall models and networking add-on available in simulink?

I am modelling a cyber-physical system. However, I want to verify the cyber properties of my system. I wonder if there is any networking add on, ethernet channel. whcih just model the networking components of my system like firewall, router etc.

Hi @Muhammad Arsal,

Below are two options that you can explore for modelling the networking components of your system in Simulink:

• "SimEvents" is an add-on for Simulink that allows you to model discrete-event systems, including networks, queues, and communication channels. You can model components like routers, switches, and network delays using this. “SimEvents” does not have explicit “firewall” blocks, but you can build custom logic to simulate firewall behaviour (e.g., blocking or allowing packets based on some rules)
• You can also create your own firewall or router models using basic Simulink blocks such as the ‘Function Blocks’

Please refer to the following documentation links for more information:

Hope this helps!
