Leveraging Amazon SageMaker Unified Studio with Identity Center and IAM-Based Domains

Why This Matters Now: The rise of machine learning (ML) in business has led to increased demands for robust, secure, and scalable ML environments. Amazon SageMaker Unified Studio, combined with AWS Identity Center and IAM-based domains, provides a powerful solution for managing ML workflows while ensuring strict access controls. This became urgent because organizations need to handle sensitive data and comply with regulatory requirements efficiently.

Overview of Amazon SageMaker Unified Studio

Amazon SageMaker Unified Studio is a comprehensive integrated development environment (IDE) designed for ML developers and data scientists. It provides a single workspace for building, training, and deploying ML models. Unified Studio integrates seamlessly with other AWS services, making it a versatile tool for ML projects.

Key Features of SageMaker Unified Studio

• Integrated Development Environment (IDE): Provides a Jupyter notebook interface for interactive coding.
• Model Training and Deployment: Supports various training jobs and deployment options.
• Collaboration Tools: Facilitates teamwork with features like shared workspaces and version control.
• Security and Compliance: Integrates with AWS Identity and Access Management (IAM) for fine-grained access control.

Introduction to AWS Identity Center

AWS Identity Center (formerly AWS Single Sign-On) simplifies identity management by providing a single directory for managing access to AWS resources and third-party applications. It supports SAML 2.0-based applications and offers centralized user management, permission settings, and audit trails.

Benefits of Using AWS Identity Center

• Centralized User Management: Manage user identities and access permissions from a single console.
• Single Sign-On (SSO): Enable users to access multiple AWS accounts and applications with one set of credentials.
• Compliance: Simplify compliance with audit logs and detailed access reports.

IAM-Based Domains in SageMaker

IAM-based domains in SageMaker allow you to create isolated environments for different teams or projects. Each domain is associated with an IAM role that defines the permissions for users within that domain. This setup enhances security by limiting access to only the necessary resources.

Setting Up IAM-Based Domains

To set up an IAM-based domain in SageMaker, follow these steps:

1. Create an IAM Role: Define the permissions required for users in the domain.
2. Create a SageMaker Domain: Associate the IAM role with the domain.
3. Invite Users: Invite users to join the domain and assign them to appropriate user profiles.

Example: Creating an IAM Role

# IAM Role Policy Document
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "sagemaker:*",
        "ecr:GetDownloadUrlForLayer",
        "ecr:BatchGetImage",
        "ecr:BatchCheckLayerAvailability",
        "ecr:PutImage",
        "ecr:InitiateLayerUpload",
        "ecr:UploadLayerPart",
        "ecr:CompleteLayerUpload",
        "ecr:DescribeRepositories",
        "ecr:GetRepositoryPolicy",
        "ecr:ListImages",
        "ecr:DescribeImages",
        "ecr:BatchDeleteImage",
        "ecr:SetRepositoryPolicy",
        "ecr:DeleteRepository",
        "ecr:CreateRepository",
        "logs:CreateLogGroup",
        "logs:CreateLogStream",
        "logs:PutLogEvents",
        "logs:DescribeLogStreams",
        "logs:DescribeLogGroups",
        "s3:GetObject",
        "s3:PutObject",
        "s3:ListBucket"
      ],
      "Resource": "*"
    }
  ]
}

Example: Creating a SageMaker Domain

aws sagemaker create-domain \
    --domain-name my-sagemaker-domain \
    --auth-mode IAM \
    --default-user-settings ExecutionRole=arn:aws:iam::123456789012:role/MySageMakerExecutionRole \
    --subnet-ids subnet-12345678 subnet-87654321 \
    --vpc-id vpc-12345678

Integrating SageMaker Unified Studio with AWS Identity Center

Integrating SageMaker Unified Studio with AWS Identity Center enhances security by centralizing user management and access control. This integration allows you to manage access to SageMaker resources through a single directory.

Steps to Integrate SageMaker with Identity Center

1. Enable AWS Identity Center: Set up AWS Identity Center and create a directory.
2. Configure SSO Permissions: Assign permissions to users and groups in the directory.
3. Link SageMaker with Identity Center: Configure SageMaker to use the Identity Center directory for authentication.

Example: Enabling AWS Identity Center

aws ssoadmin create-instance-access-control-attribute-configuration \
    --instance-arn arn:aws:sso:::instance/ssoins-1234567890abcdef \
    --instance-access-control-attribute-configuration '{"AccessControlAttributes":[{"Name":"CostCenter","Value":{"Source":["$CostCenter"]}}]}'

Example: Configuring SSO Permissions

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "sagemaker:*",
      "Resource": "*",
      "Condition": {
        "StringEquals": {
          "aws:PrincipalTag/CostCenter": ["12345"]
        }
      }
    }
  ]
}

Example: Linking SageMaker with Identity Center

aws ssoadmin create-account-assignment \
    --instance-arn arn:aws:sso:::instance/ssoins-1234567890abcdef \
    --target-type AWS_ACCOUNT \
    --target-id 123456789012 \
    --permission-set-arn arn:aws:sso:::permissionSet/ssoins-1234567890abcdef/ps-1234567890abcdef \
    --principal-type GROUP \
    --principal-id GRP1234567890abcdef

Best Practices for Secure Configuration

Ensuring the security of your SageMaker Unified Studio setup is crucial. Follow these best practices to maintain a secure environment:

Use Least Privilege Principle

Assign the minimum necessary permissions to IAM roles and Identity Center groups. Avoid using wildcard (*) actions and resources in your policies.

Example: Least Privilege Policy

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "sagemaker:CreateNotebookInstance",
        "sagemaker:DescribeNotebookInstance",
        "sagemaker:StopNotebookInstance",
        "sagemaker:DeleteNotebookInstance"
      ],
      "Resource": "arn:aws:sagemaker:us-east-1:123456789012:notebook-instance/*"
    },
    {
      "Effect": "Allow",
      "Action": [
        "s3:GetObject",
        "s3:PutObject"
      ],
      "Resource": "arn:aws:s3:::my-bucket/*"
    }
  ]
}

Regularly Audit Access Logs

Monitor and audit access logs to detect any unauthorized access attempts. Use AWS CloudTrail to log and monitor API calls made to SageMaker and Identity Center.

Example: Enabling CloudTrail

aws cloudtrail create-trail \
    --name MyCloudTrail \
    --s3-bucket-name my-cloudtrail-bucket \
    --is-multi-region-trail \
    --enable-log-file-validation

Implement Multi-Factor Authentication (MFA)

Require MFA for all users accessing SageMaker and Identity Center. This adds an extra layer of security by requiring a second form of verification.

Example: Enabling MFA

aws iam update-virtual-mfa-device \
    --serial-number arn:aws:iam::123456789012:mfa/user \
    --authentication-code1 123456 \
    --authentication-code2 654321
