You see, that area of Iceland is actually rather swampy and it is sort of daft to build a bridge on a swamp, but they build them all the same, just to show it can be done. Then it sinks into the swamp, so they build a second one. That sinks into the swamp. So they build a third. That usually burns down, falls over, and sinks into the swamp. But the fourth bridge -that stays up. And that's what you're going to get, Lad, the strongest bridges in all of Europe.
I really doubt that anyone living in just the three events I linked to would be comforted by the fact that the world as a whole is now a better place to live. They would certainly not think they were living in a world that demonstrates "...the acceleration of cultural and technological innovation that is the hallmark of modern human success".
So where do we set the goalposts? How do we define "success" in creating a more cooperative and less violent culture? That is what I want to know when I look out at the world as it is now. Yes, it is a better place but I think it is far from a success when we still have nations using force to solve their problems. I suppose for me the definition of success would be an end to war and I think we are very, very far away from that.
I am not a pessimist, but I will say that we are a far cry from being a "success".
In most companies of any size that I have been involved with an application portfolio would need to list the ports and services that it would use.
You could also turn off the firewall, run nmap against the system and see what ports are open. Ask the developers what their application uses from the ports discovered and then turn the firewall on again. Then block what you don't need and open what you do. Yeah, it's a pain in the ass, but not every machine inside your network is always going to play nice with everyone else, so firewalls on important systems are needed.
Wonder where I can get a firmware upgrade?
Or you could run a virtual firewall (running an Open VPN client to your main firewall) and admin station inside your laptop and tunnel from your workstation to your firewall.
There are a ton of ways to do this depending on the time and options you have access to.
No need to block entire countries - just allow SSH access to those systems that need it.
Now, if you want to talk about blocking access to your web or mail server from anyone in East Elbonia, then you can implement a package like Country Block, or use a service like this one, depending on your firewall.
The lesson from this? Restrict access to important services via a whitelist, block access to public services with a deny list.
