Linkerd enforces authorization policies using SPIFFE/SPIRE workload identities for secure service access

Linkerd leverages SPIFFE/SPIRE to establish and enforce workload identities for both Kubernetes and non-Kubernetes services. By integrating with SPIRE, Linkerd proxies obtain SPIFFE Verifiable Identity Documents (SVIDs), which are then used as the basis for Linkerd's mutual TLS (mTLS) and fine-grained authorization policies, ensuring secure and identity-aware access control for services within and beyond the mesh.

Istio enforces workload identity for service access using SPIFFE/SPIRE-issued SVIDs

Istio, leveraging SPIFFE/SPIRE as its certificate authority, enforces granular workload identity for mutual TLS (mTLS) and authorization policies within the service mesh. SPIRE issues cryptographically verifiable identities (SVIDs) to workloads, which Istio's Envoy proxies consume via the Envoy SDS API to authenticate services and control access for various operations, including AI retrieval and general service access. This integration provides enhanced attestation capabilities and supports trus

Entra ID uses OAuth 2.0 RFC 8693 to propagate identity to API gateways for AI access control

Microsoft Entra ID issues OAuth 2.0 access tokens and participates in RFC 8693 token exchange flows that delegate access between APIs, while API gateways in the API Gateways and Data Mesh Gateways for AI Access category validate Entra-issued JWTs and forward authorized requests, allowing standardized token exchange and validation at the A-C interface to enforce identity-aware AI service access.
