SageMaker.11: Data quality jobs network isolation

Written and reviewed by Emnode · Last reviewed

What does AWS Security Hub SageMaker.11 check?

SageMaker.11 fails when a data quality job definition has `EnableNetworkIsolation` set to false, leaving the job's containers internet-enabled by default.

Why does SageMaker.11 matter?

Network isolation does more than block packets: when on, AWS withholds AWS credentials from the container's runtime entirely, so even a malicious or buggy container has nothing to call the AWS API with. For data quality jobs, where SageMaker stages the input and output for you, isolation rarely costs anything — and leaving it off means a job container can reach out unrestricted.

How do I fix SageMaker.11?

  1. List data quality job definitions and check `EnableNetworkIsolation` to find the failing ones.
  2. Recreate each definition with isolation enabled — the setting is immutable, so it cannot be patched.
  3. Confirm the job's input and baseline data are staged so it does not need a runtime call-out under isolation.
  4. Make isolation the default in your IaC, and fix siblings .12 and .14 in the same pass.
