Hey there folks,
I’m trying to figure out how to configure my UFW, and I’m just not sure where to start. What can I do to see the intetnet traffic from individual apps so I can know what I might want to block? This is just my personal computer and I’m a total newbie to configuring firewalls so I’m just not sure how to go about it. Most online guides seem to assume one already knows what they want to block but I don’t even know how/where to monitor local traffic to figure out what I can/should consider blocking.
I fail to see why this is bad advice. Sure you could just disable the firewall on your computer on a local network. But that’s under the assumption that you can trust everything on your local network. What if it’s a laptop? Do you also trust any public networks you may connect to on the go? Having firewall both on the router and on your computer provides an additional layer of security, and I think that’s good advice in general. You can for example set it up to only allow incoming connections when connected to your home network for example.
There is a difference between good practice and fear mongering. You aren’t going to lose it all because you didn’t turn on the Firewall.
