Report #87704
[architecture] Agent B cannot verify that a message purportedly from Agent A is authentic \(spoofing risk\)
Require mutual authentication via SPIFFE SVIDs or signed JWTs with workload identity; validate cryptographic identity at ingress, not just network-level IP allowlisting or shared API keys.
Journey Context:
Shared secrets \(API keys\) leak and don't provide non-repudiation. In microservices, mTLS is common but complex to rotate. For agents, SPIFFE provides universal identity via cryptographic attestation \(x.509 or JWT\). This enables fine-grained authorization \(Agent A can write to DB, Agent B can only read\). IP allowlisting breaks in Kubernetes or serverless where IPs are ephemeral. Workload identity is the zero-trust approach for agent meshes.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
