A few notes on AWS Nitro Enclaves: KMS integration
Trail of Bits details subtle KMS-integration pitfalls in AWS Nitro Enclaves where loose attestation policies can silently erode the confidential-computing trust boundary.
Summary written by editorial AI · Source link below
Nitro Enclaves and Key Management Service (KMS) feel like a natural fit: since the KMS can verify attestation documents generated by the enclaves, developers can offload key management tasks from their applications to the AWS-managed service. But integrating an external service with your trusted enclaves comes with new threats, even if that service comes from the same provider. In this blog post—the third in our series on Nitro Enclaves, following our posts on attack surface and images and attes
Editorial Analysis
Organisations relying on Nitro Enclaves for confidential computing may overestimate isolation guarantees if KMS attestation policies are not tightly scoped—a risk amplified as more EU workloads move to enclave-backed architectures.
Review all Nitro Enclave KMS key policies for overly broad condition keys and validate that attestation documents are checked against expected PCR measurements.
