Inspired by this comment to try to learn what I’m missing.
- Cloudflare proxy
- Reverse Proxy
- Fail2ban
- Docker containers on their own networks
Another concern I have is does it need to be on a separate machine on a vlan from the rest of the network or is that too much?
There are ip lists that let you iptables drop all traffic from China and Russia.
Strongly recommend.
I was auto banning all countries but my own but now I’m hosting one resource that has an audience including Chinese…
Good advice outside of this use case! :)
Yeah, there were other countries to ban, but those 2 cut my attacks down 90%.
Also consider a honeypot that triggers when anyone tries to ssh it at all.
My UDM has this capability. I’ve blocked quite a few countries that it logged as trying to get into my network. Great little internet cylinder.
Have the rack mounted one, I usually roll my own router but I’m glad to have someone else making sure I don’t do anything stupid for security.
It’s not perfect, but it’s peace of mind.
