Managing Access to AI Training Environments via OpenID

Question

Pulumi · Accepted Answer

Managing access to AI training environments typically requires a system that offers secure authentication and authorization. OpenID Connect (OIDC) is a popular identity layer on top of the OAuth 2.0 protocol which allows clients to verify the identity of a user as well as to obtain basic profile information about them in an interoperable and REST-like manner.

In order to manage access to AI training environments, it is essential to integrate your AI resources with an identity provider that supports OpenID Connect. Pulumi offers various ways to manage cloud resources across different providers, and integrating OpenID is possible within cloud services that support IAM (Identity and Access Management) or equivalent services.

Below is a Pulumi Python program that demonstrates how you could manage access to an AI training environment on AWS using Amazon Cognito, which supports integrating with OpenID Connect providers. Amazon Cognito provides user management and authentication functions that can be integrated into your app. Users can authenticate with a user pool and receive a JWT token, which can then be used to authenticate to the AI training environment.

```python
import pulumi
import pulumi_aws as aws

# Create an Amazon Cognito User Pool to manage user access.
user_pool = aws.cognito.UserPool("aiUserPool",
    password_policy=aws.cognito.UserPoolPasswordPolicyArgs(
        minimum_length=8,
    ))

# Create a User Pool Client that will be able to interface with the user pool.
user_pool_client = aws.cognito.UserPoolClient("appClient",
    user_pool_id=user_pool.id,
    explicit_auth_flows=["ALLOW_REFRESH_TOKEN_AUTH"],
    generate_secret=True,  # Generate a secret for the client, needed for OIDC client credentials flow
    allowed_oauth_flows=["code", "implicit", "client_credentials"],  # Allow different OIDC flows
    allowed_oauth_scopes=["openid", "profile"],  # Scopes that the client is allowed to request
    callback_urls=["https://www.example.com/callback"],
    logout_urls=["https://www.example.com/signout"],
    default_redirect_uri="https://www.example.com/callback",
    supported_identity_providers=["COGNITO"],  # Define the identity providers to support
    )

# Create an Identity Provider configuration for an external OIDC provider.
# This is where you'd specify the configurations of your external OpenID provider.
oidc_provider = aws.cognito.IdentityProvider("oidcProvider",
    user_pool_id=user_pool.id,
    provider_type="OIDC",
    provider_details={
        "client_id": "external_provider_client_id",
        "client_secret": "external_provider_client_secret",
        "authorize_scopes": "openid profile",
        "attributes_request_method": "GET",
        "oidc_issuer": "https://example-issuer.com",
        # ... other OIDC provider details ...
    },
    attribute_mapping={
        "username": "sub",  # Map the 'sub' claim from OpenID provider to Cognito's 'username'
        "email": "email",  # Map the 'email' claim to Cognito's 'email'
    })

# Export the user pool id and user pool client id for clients to use.
pulumi.export("user_pool_id", user_pool.id)
pulumi.export("user_pool_client_id", user_pool_client.id)
```

In the code above:

- We've created an Amazon Cognito User Pool, `aiUserPool`, which is where your users will live.
- A User Pool Client `appClient` is then created. This client will be used by your application to interact with the user pool.
- The `oidcProvider` resource is where we configure our external OIDC provider. The details such as `client_id`, `client_secret`, and `oidc_issuer` have to be obtained from your OIDC identity provider.

This setup also permits leveraging other OIDC flows such as authorization code flow, implicit flow, and client credentials flow as supported by Amazon Cognito.

After setting up the user pool and client, you can use Amazon Cognito's built-in hosted UI for authentication, or you can integrate it with your application's authentication flow.

Furthermore, to protect your AI training environment, the JWT tokens issued by Amazon Cognito upon successful authentication can be passed to your training environment. This can then be used by your environment's authorization system to grant or deny access to resources.

This code is just an example of how you can start creating a secure environment for managing access to your AI resources. Depending on the specifics of the cloud provider and the AI resources you are using, you might need to expand on this script further.

Remember, always keep your `client_secret` and other sensitive details secure. Do not hard-code them into your Pulumi program. Use Pulumi's [`Config`](https://www.pulumi.com/docs/intro/concepts/config/) to manage secrets and other configuration safely.
