In light of evolving system architectures—particularly with the rapid expansion of containerized and cloud-native environments—what are the current best practices for performing thorough penetration testing against such platforms? Specifically, is there evidence that conventional vulnerability scanning tools and methodologies are insufficient for identifying advanced threat vectors or zero-day vulnerabilities in these dynamic settings?
Furthermore, what refined manual testing techniques would you recommend to complement automated scanning efforts, especially when addressing security controls in container orchestration frameworks (e.g., Kubernetes) and multi-tenant cloud infrastructures? Any insights on integrating threat modeling, red teaming exercises, or novel use-cases that reflect the contemporary threat landscape would be highly valuable.
