Every security review hits the same wall: the image is scanned, signed and pinned, but what the workload is allowed to reach lives somewhere else. Docker Sandbox Kits move that answer into the artifact, as an open standard on OCI. www.msbiro.net/posts/docker...

msbiro.netDocker Sandbox Kits: An Open Standard for Authority as CodeDocker Sandbox Kits are an open standard for authority as code: one OCI image carries a workload, its network policy and credentials. Planned for CNCF.

New lab: Apple Container 1.5.0 creates a Kubernetes cluster natively on Apple silicon, and SIGHUP Distribution installs cleanly on top. Kernel backstory, temporary k8s start removal, and an x86_64 furyctl cache quirk, all verified end to end. www.msbiro.net/posts/apple-...

Opening a repo is not always read-only. A trusted VS Code workspace can run ย tasks.jsonย  on folder open. That makes the IDE part of your supply chain. A guide to malicious tasks, Workspace Trust, and untrusted repos: www.msbiro.net/posts/shift-... #DevSecOps #VSCode

It's 2026 and I still get asked why encrypting secrets with git-crypt isn't enough. Short answer: encryption solves confidentiality, not revocation, audit logging, or dynamic secrets. DORA and NIS2 remove any remaining excuse. www.msbiro.net/posts/secret...

msbiro.netIn 2026 I Am Still Asked Why You Need a Centralized Secrets ManagerWhy a centralized secrets manager is non-negotiable in 2026: the operational limits of git-crypt and sealed-secrets style tools, the DORA and NIS2 mandate, and why OpenBao is now the open source secre...

In 2026 I still get asked why enterprises need a hardened container image catalog. DORA and NIS2 mandate it. Container base images are infrastructure and deserve the same governance we always applied to operating systems. www.msbiro.net/posts/harden... #devsecops #nis2
