Securing Kubernetes Supply Chains with SBOM & Sigstore

Explore a production-proven, security-first approach to Kubernetes supply chain security using SBOMs and Sigstore to safeguard your DevSecOps pipelines. Introduction to Supply Chain Security in Kubernetes Bold Claim: "Most Kubernetes environments are one dependency away from a catastrophic supply chain attack." If you think Kubernetes security starts and ends with Pod Security Policies or RBAC, you're missing the bigger picture. The real battle is happening upstream—in your software supply chain . Vulnerable dependencies, unsigned container images, and opaque build processes are the silent killers lurking in your pipelines. Supply chain attacks have been on the rise, with high-profile incidents like the SolarWinds breach and compromised npm packages making headlines. These attacks exploit the trust we place in dependencies and third-party software. Kubernetes, being a highly dynamic and dependency-driven ecosystem, is particularly vulnerable.
