AI Infrastructure User Management via Vault and Okta

Question

Pulumi · Accepted Answer

To manage user identities and access in a secure infrastructure environment, we can integrate HashiCorp Vault, a secrets management tool, with Okta, an identity management service. Using Vault, you can leverage Okta as an authentication method, allowing users authenticated by Okta to access secrets stored in Vault.

Here is how the integration works:

1. **Vault Okta Authentication Backend**: This is a component within Vault that allows for user authentication using Okta credentials. The backend allows you to map Okta users and groups to Vault policies and use them to control access to secrets.

2. **Auth Backend User**: Represents user entities in Vault that can authenticate using the Okta backend.

3. **Vault Okta Authentication Backend Group**: Represents groups in the Okta authentication backend. You can associate Vault policies with Okta groups.

4. **Vault MFA with Okta**: Vault supports multi-factor authentication (MFA) with Okta. This makes your infrastructure more secure by requiring a second form of verification.

Let's write a Pulumi program in Python to set this up. We will be using the `pulumi_vault` provider to create and configure the necessary Vault resources for Okta integration.

```python
import pulumi
import pulumi_vault as vault

# Vault must be pre-configured in your environment, including enabling Okta authentication.

# Configure the Vault Okta authentication backend
okta_auth_backend = vault.okta.AuthBackend("oktaAuthBackend",
    description="Okta auth backend",
    organization="your-okta-org", # Replace with your Okta organization
)

# Define a user that will authenticate using Okta
auth_backend_user = vault.okta.AuthBackendUser("oktaAuthBackendUser",
    username="test-username", # Replace with the actual Okta username
    path=okta_auth_backend.path, # Reference to the Okta auth backend
    groups=["developers"], # Okta groups the user is part of
    policies=["read-secrets"], # Vault policies the user will get upon authentication
)

# Define a group in Okta authentication backend
auth_backend_group = vault.okta.AuthBackendGroup("oktaAuthBackendGroup",
    groupName="developers", # The corresponding group in Okta
    path=okta_auth_backend.path, # Reference to the Okta auth backend
    policies=["read-secrets"], # Vault policies associated with the group
)

# Output the authentication backend path for reference
pulumi.export("okta_auth_backend_path", okta_auth_backend.path)
```

In this program:

- We initialize an Okta authentication backend with `vault.okta.AuthBackend`. This requires specifying your Okta organization and optionally a description for the backend.
- We create a Vault user entity that is associated with an Okta username using `vault.okta.AuthBackendUser`. This user is thereafter linked to specific Vault policies and Okta groups.
- We also create a Vault group entity that corresponds to an Okta group using `vault.okta.AuthBackendGroup`. Vault policies are mapped to this group so that all members of the corresponding Okta group adhere to these policies when accessing Vault.

Remember to replace `"your-okta-org"` and `"test-username"` with the actual organization and username you intend to use from Okta. You will also need to configure the policies like "read-secrets" ahead of time or replace them with already existing policies in your Vault setup.

After running this program, authenticated Okta users will be able to access secrets in Vault according to the policies you have defined.

Ensure that you have installed the required Pulumi providers and that you are authenticated with Vault and Okta accordingly. This Pulumi program assumes that the necessary Vault authentication configuration is already set up in your environment including the enabling of Okta authentication.
