This practical workshop explores common threats, attack scenarios, and proven strategies for securing Helm charts through Cloudsmith's artifact management, maintaining supply chain integrity and regulatory compliance. Topics include: verifying every asset (public Helm charts, dependencies, and images from popular OSS projects before deployment); automating compliance with Trivy and enforcing runtime OPA Gatekeeper security policies in real-time; preventing supply chain attacks by auditing and managing Helm charts before distributing through secure repositories; and acknowledging the manual overhead, as most charts are insecure-by-default and require further security checks by your team. Bonus: Hands-on Instruqt lab platform that analyzes actual insecure chart templates and demonstrates how to scan and detect vulnerabilities with open-source tools, implement security standards, and properly validate Helm charts prior to production Kubernetes deployment.
