9+ DevSecOps Governance Policies
🛡️ 9+ DevSecOps Principles Baked Into This Studio
1. User namespace isolation (userns-remap) • 2. cgroup v2 memory & CPU limits • 3. CycloneDX SBOM verified containerd binaries • 4. Hardened non-root microVMs • 5. Kyverno RuntimeClass enforcement • 6. eBPF kernel tracing via Tetragon • 7. Declarative systemd & Ansible provisioning • 8. containerd Prometheus metrics (:1338) • 9. OOM score adj auto-protection (-999).
