For users with public facing services: How does the current explosion of AI-discovered vulnerabilities affect your threat model and willingness to be public facing? (lemmy.ml)

PHP, TLS, etc.. We appear to be facing a tsunami of vulnerabilities being discovered in record time. Further, the window to act on these vulnerabilities has basically closed to zero; hackers' tools now automatically fold the very latest vulnerabilities into their botnets within minutes/hours of discovery. I have always been extremely reluctant to expose any of my services - even with the latest and greatest security tools. My choice to stay totally within the confines of tailscale seems vindicated given this week's news. How are you all taking this?

This was the final push that convinced me to rebuild my server from scratch! I started doing so 3 weeks ago :D

I was running my containers on a single good old Debian, that I replaced with Proxmox. I set up several VM that don't share anything between them :

  • One for all the services I don't really care about, like game servers and utilities with no personal data.
  • A second one for services in need of a GPU passthrough (Immich and Jellyfin) and partial access to some of my data (photos and movies in this case)
  • And a third one that gets access to all my personal data, only hosting a container for WebDAV access and a web file browser. I might hide these two services behind a VPN in the future if I feel like doing so, for now it is still to practical to have them freely available...
  • A last VM is running network related app like my reverse proxy.

I should have done this years ago, but I'm still learning and learning costs time :p

Next I want to hide all of Internet facing services behind an identity provider/application proxy (I don't really know if it is the right way to name it ?) like Authentic to totally block access to any content from unauthorized visitors.

I guess I'll be mostly fine once this is done ^^

Your separation between VMs is exactly what I want to do. But given how I'm still rocking a single truenas machine running all my containers, I've got a quite a bit of setup to do... Like you said, rebuilding everything is a slog.
