I am in the process of completing PCI compliance for my office and one of the requests is a list of ports and services in use. I am not familiar with firewalls so bear with my ignorance and this question. Is there a report within the Meraki appliance that could be generated to show the ports in use? Or can someone explain how I can get this information and create my own report and be able to show auditors how the info was gathered?
I would download nmap and run a scan against its IP address. Then you have measured the actual answer. Otherwise you can only document things you know about - you can't document something you don't know exists.
