In my home lab, I “treat lab like prod” — scan every container with Trivy before it runs and email myself a nightly CVE diff; cheap and it catches supply‑chain junk we all ignored pre‑SolarWinds (Trivy). If you’re mostly on VMs, Nessus Essentials works, but tune the policy or it’ll drown you in mediums.

Since the ‘pre-SolarWinds’ chat last week, I started signing and verifying every image with cosign in my home lab; an admission webhook on k3s blocks anything without a valid signature, which has kept surprise drift to zero. If that feels heavy, pin images to digests first and add verification later.

Quick tip: I schedule GitHub - projectdiscovery/nuclei: Nuclei is a fast, customizable vulnerability scanner powered by the global security community and built on a simple YAML-based DSL, enabling collaboration to tackle trending vulnerabilities on the internet. It helps you find vulnerabilities in your applications, APIs, networks, DNS, and cloud configurations. to run every Sunday night against my sandbox ingress and compare the report diff; anything new and >medium opens a ticket in Gitea automatically, which catches config drift faster than waiting on CVE feeds. If that’s too heavy, trim to the default templates and rate‑limit, but don’t skip the diff — the “what changed since last week” view is the real time‑saver.

@jpierce402 Prioritization by exposure saved me: I label k3s workloads behind ingress as public and make CI fail only on CVEs in those images; internal-only stuff queues for the weekend window… Small caveat — host kernel/driver CVEs bypass the queue every time.

I switched to building SBOMs with syft and letting grype diff against the previous build; only ‘net-new’ vulns open a ticket, and known issues get a 7‑day SLA instead of alert fatigue. Caveat: grype can be chatty on distroless, so Trivy tends to be saner there.

I sign/verify home-lab images with cosign: GitHub - sigstore/cosign: Code signing and transparency for containers and binaries; solid ‘pre-SolarWinds’ drill. If that feels heavy, just pin image digests.

Quick tip from my home lab: before patching, I snapshot the VM (or ZFS dataset), run Trivy in fs mode on /, patch, then compare results and only keep the update if it doesn’t add new high/critical CVEs; otherwise I roll back and pin. Not perfect — Trivy can be noisy — but it’s been a solid ‘pre-SolarWinds’ drill for me: GitHub - aquasecurity/trivy: Find vulnerabilities, misconfigurations, secrets, SBOM in containers, Kubernetes, code repositories, clouds and more.
