RATS: Remote Posture Assessment + EAT for Systems, Containers, and Applications — draft-ietf-rats-posture-assessment, draft-ietf-rats-eat#

IETF 123 (Madrid) digest Program Adjacent pick Madrid · 19–25 July 2025

  • Tier: Adjacent
  • Why: Attestation is the trust root under workload identity — "is this workload running what it claims, on hardware I trust?" The posture-assessment draft explicitly extends to containers and applications at scale, which connects attestation to the WIMSE/agentic-identity world you track.
  • What: eat defines the Entity Attestation Token; posture-assessment defines remote posture assessment for systems, containers, and applications at scale. (from abstract only)
  • How: EAT carries signed claims about an entity's state; posture assessment frames how verifiers consume that evidence across many targets.
  • Where applicable: General; the container/application angle is the relevant one for cloud-native estates.
