Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.
-
No low-effort posts. This is subjective and will largely be determined by the community member reports.

firewalls are not for defending against 0 days. it is about access control, and reducing, sometimes even minimizing access to potentially vulnerable services. firewalls are not an infallible security tool, but there is no such thing either. the reason to use it is to restrict access such that fewer attackers can take advantage of a potential vulnerability.
there are intrusion detection/prevention systems that could do more, but it's unlikely they will protect against 0 days, because 0 days are undiscovered and unknown issues.
it does. its useful to force traffic through a firewall. its for limiting what has access to what. if you wouldn't use vlans, hosts on the network would not care about your firewall because they can just go straight to the destination.
I'm not sure I understand your argument, but I think what you say is, firewalls are not infallible so they are useless
I'll try an analogy to explain better. The firewall is a lock on the door to your house. Vlans are a rule that to go from one room to another, you must go back out the locked door and back in.
So an attacker tries to come in and can't pick the lock. You are safe.
Another attacker can pick the lock and get into a room. But if they can pick the lock for one room, they can pick the same lock again and get into any other rooms because it's the same lock protecting every room in the house.
