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.
@Shdwdrgn @Cornflake_Dog false. a firewall can indeed have a default block everything policy, but this is still a configurable option
Sure it CAN be configured, but the typical policy of firewalls is to start from a position of blocking everything. From what I’ve seen, on Linux the standard starting point is blocking all incoming and allowing all outgoing. On Windows the default seems to be blocking everything in both directions. Sure you could start with a policy of allowing everything and block only selected ports, but what good is that when you can’t predict what ports an attacker might come from?
