Monitor for up ports as alert
The idea is to add an option to create an alert if a port is opened (and not closed as usual).
The goal is to detect firewall misconfiguration.
For example, monitor the port SSH 22.
If the port is accessible, trigger an alert.
Thanks for this suggestion, this is something I was thinking about too and which has been requested a couple time. It's currently low priority but likely to be added later.
