[Discussion] Auto-disable Remote Access on Vunerable Selfhosted Services (bookwormstory.social)

Hi guys I was wondering if there is a streamlined way to disable remote acess to a selfhosted service (say at a reverse proxy level) if a published security vunerability is present.

I know, ideally you want to keep all your selfhosted services up to date. However on certain selfhosted service auto updates may not be viable (due to major changes between updates) and you being unavailable 24/7 to respond to vunerabilities.

Curious on your thoughts and suggestions. So far the only middle ground I can find is realying on a vpn wireguard, tailscale, etc.

The first thing that comes to mind is a combination between SBOMs generated for your self-hosted services (trivy, syfy, etc) which are pushed to OWASP Dependency-Track and whenever some vulnebrabilies are detected (note: you'll get lot of notifications if the application is using a lot of libraries), trigger an event (not sure if node red can help here) which would run a script to disabled the vhost. (just a thought. I haven't seen an actual solution)
