When Does Authorization End? Effect Closure at Provider Boundaries

The paper formalises 'effect closure' — the risk that authorised work continues producing policy-violating effects after revocation — exposing a subtle gap in distributed-system access control that provider contracts alone do not resolve.

arXiv:2609.02866v1 Announce Type: new Abstract: Revocation completion, clean state, or operation success can leave authorized work able to cause an effect the application rejects while the provider stays within its contract. We call the absence of all such paths policy-relative effect closure, or effect closure for short. Thus, a grant is closed when its existing authorizations retain no such path, and it cannot issue any new ones. We present EFFECTBOUND, which uses an evidence-supported fini

Editorial Analysis

Why it matters

Incomplete revocation effects in distributed systems can leave residual authority active across provider boundaries — a risk amplified by multi-cloud and microservice architectures.

What to do

Review authorization revocation flows in multi-provider architectures for residual-effect gaps, especially at cloud-provider boundaries.
