I noticed after installing the latest bOS Server, that any port and any protocol is enabled in the Windows firewall, creating a serious safety breach into the system. Especially if the server is connected to the internet or the home network is full of iot devices that are easily compromised. This is a serious security issue. Also looking at the amount of hack or intrusion attempts that happen every day on bOS, as parts of it are connected to the internet. A compromised bOS server gives the attacker full access to the rest of the network with these firewall settings. And it is a real risk if you consider the poor TLS protocols that where still in use before bOS 4.9.0.
I also noticed that multiple Firewall entries are created and probably not cleaned after upgrading to a newer version of bOS.
What are the minimum ports/protocols needed by bOS to function properly?
