Which solution will meet the company’s security requirements?
Connect the SageMaker notebook instances that are in the VPC by using AWS Site-to-Site VPN to encrypt all internet-bound traffic. Configure VPC flow logs. Monitor all network traffic to detect and prevent any malicious activity.
Configure the VPC that contains the SageMaker notebook instances to use VPC interface endpoints to establish connections for training and hosting. Modify any existing security groups that are associated with the VPC interface endpoint to allow only outbound connections for training and hosting.
Create an IAM policy that prevents access the internet. Apply the IAM policy to an IAM role. Assign the IAM role to the SageMaker notebook instances in addition to any IAM roles that are already assigned to the instances.
Create VPC security groups to prevent all incoming and outgoing traffic. Assign the security groups to the SageMaker notebook instances.
Explanations:
This option proposes using AWS Site-to-Site VPN to encrypt internet-bound traffic, which contradicts the requirement that the SageMaker notebook instances must not have internet connectivity. Additionally, VPC flow logs do not prevent internet access.
This option configures VPC interface endpoints for SageMaker, which allows the notebook instances to access Amazon S3 without requiring internet access. It aligns with the security policy by ensuring that the instances remain isolated from the public internet while still being able to interact with necessary AWS services.
While creating an IAM policy to prevent internet access is a good practice, it does not directly prevent network connectivity to the internet. IAM policies govern permissions within AWS, but they do not control the network traffic from the instances. Therefore, this option does not fully meet the requirement.
Creating security groups that prevent all incoming and outgoing traffic would isolate the SageMaker notebook instances entirely, making them unusable for training or hosting. The requirement is to ensure no internet connectivity while still allowing necessary AWS service access, which this option does not accomplish.
I think the answer is:
Configure the VPC that contains the SageMaker notebook instances to use VPC interface endpoints to establish connections for training and hosting. Modify any existing security groups that are associated with the VPC interface endpoint to allow only outbound connections for training and hosting.
