SageMaker.13: Model quality jobs inter-container encryption

Written and reviewed by Emnode · Last reviewed

What does AWS Security Hub SageMaker.13 check?

SageMaker.13 fails when a model quality job definition has `EnableInterContainerTrafficEncryption` set to false, leaving traffic between the job's containers unencrypted.

Why does SageMaker.13 matter?

Model quality monitoring runs distributed jobs that shuttle prediction and ground-truth data between containers. Off by default, the flag means that data crosses the network in the clear. The setting is immutable — there is no UpdateModelQualityJobDefinition that flips it — because the encryption decision shapes how SageMaker provisions the cluster's TLS material up front.

How do I fix SageMaker.13?

  1. List model quality job definitions and check `EnableInterContainerTrafficEncryption`.
  2. Delete and recreate each failing definition with the flag set to true — there is no in-place patch.
  3. Make the flag a required field in your job-definition IaC so every new monitoring job is compliant.
  4. Remediate the sibling controls (.9, .10, .15) together, as they all check this flag.
