Security Considerations on Istio's CRDs with Namespace-based Multi-Tenancy Addressing man-in-the-middle weaknesses in namespace-based multi-tenant setups. The Istio project wants to address a possible Man-in-the-Middle (MITM) attack scenario in which a VirtualService can redirect or intercept traffic within the service mesh. This affects namespace-based multi-tenancy clusters where tenants have th...
In a skeptical analysis, it is essential to consider the implications of this vulnerability for users deploying Istio in multi-tenant clusters. While Istio's mesh gateway option provides convenience and flexibility, it exposes potential security risks when used in namespace-based multi-tenancy setups or multiple cluster deployments. Steelman: The article presents a strong argument for the need to address MITM attack vulnerabilities in Istio's service mesh, especially in multi-tenant environments...
