Erich Blume 4b85e8ca73 Add compensating controls framework with review tooling
Introduce compensating-controls.yaml to track named controls that
justify suppressed security findings. Each control has a description,
verification notes, and last-reviewed date.

Update all Prowler mutelist descriptions to reference controls via
"CC: <id>" prefix instead of restating findings. Nine controls cover:
single-user-cluster, tailscale-network-isolation, local-registry,
sso-gated-admin-tools, operator-managed-pods, ephemeral-privileged-jobs,
trusted-ci-only, init-container-isolation, observability-stack-audit.

Add mise task (review-compensating-controls) that surfaces the most
stale control with all codebase references, and how-to doc
([[review-compensating-controls]]) explaining the review process.

Security & Compliance

Security posture and compliance scanning for BlumeOps infrastructure.

Compliance frameworks

Framework Tool Cluster Notes
CIS Kubernetes Benchmark v1.11 prowler minikube-indri Weekly CronJob, ~82 checks
PCI DSS v4.0 (K8s mapping) prowler minikube-indri Reuses CIS checks mapped to PCI requirements
ISO 27001:2022 (K8s mapping) prowler minikube-indri Partial — 22 of 92 controls mapped

Scanning tools

  • prowler — CIS Kubernetes Benchmark scanner (weekly CronJob)
  • kingfisher — Secret detection and live validation for Forgejo repos (weekly CronJob + prek hook)

Identity & access

  • authentik — SSO/OIDC provider for all web services
  • RBAC — Kubernetes role-based access control (audited by Prowler RBAC checks)

Network & TLS

  • caddy — TLS termination for *.ops.eblu.me services
  • flyio-proxy — public ingress via Fly.io tunnel
  • Tailscale — zero-trust mesh networking across all nodes

Secrets management

Reports

All compliance scan reports are stored on sifaka:/volume1/reports/. See read-compliance-reports for access and interpretation.

Compensating controls

Suppressed findings reference named compensating controls tracked in compensating-controls.yaml (repo root). Each control has a review date and verification steps. See review-compensating-controls for the review process.

Known gaps

  • No SOC 2 compliance mapping for Kubernetes (Prowler only maps SOC 2 for AWS/Azure/GCP)
  • k3s control plane checks produce no results (embedded binary, no static pods) — consider kube-bench
  • Container image scanning covers blumeops/* images only — upstream images (ollama, immich, etc.) are not scanned
  • IaC scanning covers the blumeops repo only — no scanning of third-party Helm charts or vendored manifests
