Report #88360

[architecture] Privileged agent actions executed by unauthorized agents forging identity headers in inter-service calls

Adopt SPIFFE/SPIRE for cryptographic identity: issue short-lived X.509 SVIDs \(SPIFFE Verifiable Identity Documents\) to each agent workload; verify mTLS and SVID at every hop, rejecting connections from unknown or expired identities

Journey Context:
Static API keys or IP whitelisting fail in Kubernetes where IPs are ephemeral and keys leak in logs. SPIFFE provides attestation based on workload identity \(pod identity, not network location\). This prevents lateral movement if one agent is compromised—it cannot impersonate another's SPIFFE ID without the private key \(stored in tmpfs and rotated hourly\). Alternative: service mesh \(Istio\) which uses SPIFFE under the hood, but explicit SPIFFE is framework-agnostic and works across clouds. Requires SPIRE server for attestation, adding infrastructure complexity but essential for zero-trust multi-agent mesh.
