Researchers Present Kubernetes Namespace Isolation Assessment Methodology
7.8
Relevance Score
Lorin Lehawany presents a structured methodology at KubeCon + CloudNativeCon Europe 2026 for assessing security risks in Kubernetes clusters that use Namespace-based Multi-Tenancy. The three-phase approach—detect tenancy presence, assess tenant interactions with shared components, and remediate weaknesses—emphasizes indirect multi-tenancy vectors like CI/CD pipelines, ML platforms, scripting features, and hard-coupled clusters that can bypass Namespace isolation and compromise confidentiality, integrity, and availability.
Scoring Rationale
Actionable, broadly applicable methodology from KubeCon; limited by single-source presentation and lack of peer-reviewed validation.
