As we speak, we’re excited to announce that Amazon SageMaker now helps the flexibility to configure Occasion Metadata Service Model 2 (IMDSv2) for Pocket book Situations, and for directors to manage the minimal model with which end-users create new Pocket book Situations. Now you can select IMDSv2 solely in your new and current SageMaker Pocket book Situations to reap the benefits of the newest safety and help offered by IMDSv2.
Occasion metadata is knowledge about your occasion that you need to use to configure or handle the operating occasion, by offering short-term and often rotated credentials that may solely be accessed by software program operating on the occasion. IMDS makes metadata concerning the occasion, corresponding to its community and storage, accessible by means of a particular link-local IP deal with of
169.254.169.254. You need to use IMDS in your SageMaker Pocket book Situations, just like how you’ll use IMDS on an Amazon Elastic Compute Cloud (Amazon EC2) occasion. For detailed documentation, see Occasion metadata and person knowledge.
The discharge of IMDSv2 provides a further layer of safety utilizing session authentication. With IMDSv2, every session begins with a PUT request to IMDSv2 to get a safe token, with an expiry time, which could be a minimal of 1 second and a most of 6 hours. Any subsequent GET request to IMDS should ship the ensuing token as a header, with the intention to obtain a profitable response. When the required period expires, a brand new token is required for future requests.
A pattern IMDSv1 name appears to be like like the next code:
With IMDSv2, the decision appears to be like like the next code:
Adopting IMDSv2 and setting it because the minimal model affords varied safety advantages over IMDSv1. IMDSv2 protects in opposition to unrestricted Net Software Firewall (WAF) configurations, open reverse proxies, Server-Aspect Request Forgery (SSRF) vulnerabilities, and open layer 3 firewalls and NATs that might be used to entry the occasion metadata. For an in depth comparability, see Add protection in depth in opposition to open firewalls, reverse proxies, and SSRF vulnerabilities with enhancements to the EC2 Occasion Metadata Service.
On this submit, we present you tips on how to configure your SageMaker notebooks with IMDSv2 solely help. We additionally share the help plan for IMDSv1, and how one can implement IMDSv2 in your notebooks.
What’s new with IMDSv2 help and SageMaker
Now you can configure the IMDS model of SageMaker Pocket book Situations whereas creating or updating the occasion, which you are able to do through the SageMaker API or the SageMaker Console, with the minimal IMDS model parameter. The minimal IMDS model specifies the minimal supported model. Setting to a price of 1 permits help for each IMDSv1 and IMDSv2, and setting the minimal model to 2 helps solely IMDSv2. With an IMDSv2-only pocket book, you’ll be able to leverage the extra protection in depth that IMDSv2 gives.
We additionally present a SageMaker situation key for IAM insurance policies that lets you limit the IMDS model for Pocket book Situations by means of the CreateNotebookInstance and UpdateNotebookInstance API calls. Directors can use this situation key to limit their finish customers to creating and/or updating notebooks to help IMDSv2 solely. You may add this situation key to the AWS Id and Entry Administration (IAM) coverage connected to IAM customers, roles or teams answerable for creating and updating notebooks.
Moreover, you may also swap between IMDS model configurations utilizing the minimal IMDS model parameter within the SageMaker UpdateNotebookInstance API.
Assist for configuring the IMDS model and proscribing the IMDS model to v2 solely is now accessible in all AWS Areas through which SageMaker Pocket book Situations can be found.
Assist plan for IMDS variations on SageMaker Pocket book Situations
On June 1, 2022, we rolled out help for controlling the minimal model of IMDS for use with Amazon SageMaker Pocket book Situations. All Pocket book Situations launched earlier than June 1, 2022 may have the default minimal model set to 1. You should have the choice to replace the minimal model to 2 utilizing the SageMaker API or the console.
Configure IMDS model in your SageMaker Pocket book Occasion
You may configure the minimal IMDS model for SageMaker pocket book by means of the AWS SageMaker console (see Create a Pocket book Occasion), SDK, or the AWS Command Line Interface (AWS CLI). That is an optionally available configuration, with a default worth to set to 1, that means that the pocket book occasion will help each IMDSv1 and IMDSv2 calls.
When creating a brand new pocket book occasion on the SageMaker console, you now have the choice Minimal IMDS model to specify the minimal supported IMDS model, as proven within the following screenshot. If the worth is ready to 1, each IMDSv1 and IMDSv2 are supported. If the worth is ready to 2, solely IMDSv2 is supported.
You too can edit an current pocket book occasion to help IMDSv2 solely utilizing the SageMaker console, as proven within the following screenshot.
The default worth will stay 1 till 31 August, 2022, and can swap to 2 on 31 August, 2022.
When utilizing the AWS CLI to create a pocket book, you need to use the
MinimumInstanceMetadataServiceVersion parameter to set the minimal supported IMDS model:
The next is a pattern AWS CLI command to create a pocket book occasion with IMDSv2 help solely:
If you wish to replace an current pocket book to help IMDSv2 solely, you are able to do it utilizing the UpdateNotebookInstance API:
Implement IMDSv2 for all SageMaker Pocket book Situations
You need to use a situation key to implement that your customers can solely create or replace Pocket book Situations that help IMDSv2 solely, to reinforce safety. You need to use this situation key in IAM insurance policies connected to the IAM customers, roles or teams answerable for creating and updating the notebooks, or AWS Organizations service management insurance policies.
The next is a pattern coverage assertion that restricts each create and replace pocket book occasion APIs to permit IMDSv2 solely:
As we speak, we introduced help for configuring and administratively proscribing your Occasion Metadata Service (IMDS) model for Pocket book Situations. We confirmed you tips on how to configure the IMDS model in your new and current notebooks utilizing the SageMaker console and AWS CLI. We additionally confirmed you tips on how to administratively limit IMDS variations utilizing IAM situation keys, and mentioned the benefits of supporting IMDSv2 solely.
