Hey, I’ve got a bunch of services all running in their own containers/vms on Proxmox. All of these have their own ips that are accessible from my network.
I also have a container with a reverse proxy, which acts as a gateway for access to these services (it’s IP is the only one allowed to go through the firewall of each service).
These services have http servers, no encryption. Could someone on my network listen to comms between a service and my reverse proxy?
Would have to play around with VLANs if that’s the case…
Gotcha. That makes sense. My own thoughts are that if you mitigate all of the attack surfaces you can, it ends up coming down to the robustness of the particular app. I’ve never played with keycloak, so can’t speak intelligently about that, but I’ve got authentik setup in a similar configuration. I limit access so the only way in is via either the reverse proxy or the PVE console and basically keep an ear out for security and software updates.
As I type this, it occurs to me that perhaps there’s a fail2ban integration that could be added to limit credential guessing at the keycloak webui.

I’ve got 2FA set up and required, so I’m not too worried about brute force attacks.
