Then you're a filthy normie mac book user that voted for Bernie

Use a flame supressing wall

scan and generate a list for all outgoing connections and block all IPs in that list in the hosts file/router/whatever, then keep track as you install new things?

IDK if that would work im just throwing shit out there. People could still get you using incoming connections though.

what if they use a cyber nuke?

>>57151293
Probably something like, run it under a user that has no network permissions or something. I don't know, I'm just making shit up.

>>57151497
Pepepahaha the cyber nuke gui has my sides in orbit. These hacking scenes have become parodies of themselves, I'm almost 100 percent certain they weren't taking themselves seriously with that shit show. Lel.

This would work fine, actually. But you could just do it by ports instead of IPs...in essence, you'd be filtering outbound from src=localhost and inbound from any IP.

You'll need two rules in the bottom of your firewall ruleset:

Deny Any/Any (Outbound)
Deny Any/Any (Inbound)

Run something like netstat to see what services are listening and then if you see something trusted that you want on the internet, add a rule at the top of your firewall rule chain to let it in.

Allow 127.0.0.1/80 (Outbound)
Allow Any/80 (Inbound)

Rinse and repeat.

Also, you could do this at layer 7, too, if you had some smart firewall stuff to block connections at the app layer.

I don't think you understand how the OSI model works

>>57151293
so much answers and none actually helpful at all
I am truly on /g/

OP, you need
>firewall with rules based on single programs
>assuming OS based on normie:

You can use Windows 7 (or better) build-in firewall
>which is pretty shit (the UI is TERRIBLE)
http://www.howtogeek.com/227093/how-to-block-an-application-from-accessing-the-internet-with-windows-firewall/

or some 3rd party application like

1) tear off a small piece of aluminum foil and roll it up into a thin stick
2) open up your computer and stick the aluminum stick into the port which that program uses

bernie was a puppet to attract anti-establishment voters, really sad to see people not figuring the most basic shit out.

and i'm sorry for the off-topic post, but stupidity triggers me

Sure I do. Layer 7 is at the app layer. I can filter specific requests by specific services/applications. If I want to shun outbound HTTP traffic from IE but allow HTTP traffic for some webapp, I can filter it for IE at layer 7.

It's less heavy handed than restricting traffic at the IP level. Once you get further along in your Network+ study guide, you'll understand a bit more.

With a firewall? Are you retarded or something?
