Using Istio, Linkerd, and Cilium service mesh to enforce signed-artifact, SPIFFE identity, and provenance-aware policy in production clusters.
Policy design patterns for GCP Binary Authorization that hold up in production: attestor topology, exception handling, continuous validation, and the shapes that stop a deploy-time compromise without blocking legitimate rollouts.
Three years after the landmark cybersecurity executive order, SBOM adoption is growing but uneven, secure development attestation is rolling out, and the gap between policy and practice remains wide.
CISA launched a voluntary pledge asking software manufacturers to commit to specific security improvements. Over 100 companies signed. Here is what the pledge actually requires and whether it matters.
Governments worldwide are moving to hold software vendors liable for security failures. Here is what the shifting liability landscape means for software producers and consumers.
A practical template for crafting an enterprise open-source usage policy that balances developer freedom with security and compliance requirements.
