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 mostly agree with you, but given it’s a laptop that may not always be at home. It is wise to consider enabling the firewall when connecting to other untrusted networks like Starbucks
Yes, fair point.
As I understand it, the main risk of an untrusted local network is with DNS. The best precaution being to set it manually (to 1.1.1.1 for example or ideally something less centralized). Actually I used to do that myself, running a stub DNS server on localhost. This kind of option really should be in every OS by default.
Would be interested to know the consensus on better locking down a roving laptop.
