User Management and Access Controls

Tecton access controls enable organizations to configure fine-grained governance over who and what can modify the Feature Platform and access feature data.

Access controls are configured by granting roles to principals. Most roles apply to actions that a principal can perform in a specific workspace.

info

Tecton Access Controls govern access to Tecton metadata and online features, but not access to offline data. See limitations.

Tecton Principals

In Tecton, access controls are used to specify what actions a principal is able to perform. A principal is a User, Service Account, or Principal Group.

Users

The User principal represents an individual who accesses an organization's Tecton Account by logging in with their own credentials to the Tecton UI or CLI. Users need to be configured with the appropriate Tecton access controls in order to develop with Tecton, or administer the account.

Service Accounts

The Service Account principal represents machine access to the Tecton Account, such as a training pipeline or an ML application accessing features. Service Accounts authenticate access using API keys.

Principal Groups

Tecton Principal Groups simplify the process of granting your Tecton users access to the appropriate resources. By organizing Tecton Users and Services Accounts into Groups, Administrators can simply make role changes at the Group level to govern their organization.

When a User or Service Account is added to a Principal Group, then they will inherit any roles that have been granted to said Principal Group. Principals that are members of multiple groups will inherit the union of roles across those groups.

Additionally, Administrators can automate Group membership configuration by using Identity Provider Attributes. Identity Provider Attributes automatically assign Users to Groups at sign-in time, based on attributes passed in from your Identity Provider during the Single Sign-On process.

Summary of roles and permissions

Workspace-level roles

The following roles can be granted in a workspace.

• Owner: Can perform any action in an existing workspace. The Owner role is automatically granted to the creator of a workspace.
• Editor: Can modify the workspace itself, but not other users' access. Also includes Operator's and Consumer's permissions.
• Consumer: Can access online data. Also includes Viewer's permissions.
• Operator: Can manage materialization jobs. Also includes Viewer's permissions.
• Viewer: Can view definitions and metadata.

Instance-level roles

The Admin role

Principals with the admin account type have the Admin role. The Admin role can add/remove users, grant/revoke workspace-level roles to principals and create live workspaces.

The Regular role

By default, all principals have the Regular principal role. This role grants basic permissions, such as the permission to create development workspaces and Service Accounts.

All-Workspace roles

Any of the workspace-level roles can optionally be granted across all workspaces, to a user, a group, or a Service Account. Doing so allows the user or Service Account to perform the actions allowed by that role, across all workspaces. The principal will automatically assume that role on all new workspaces created thereafter.

Only admins can assign an all-workspace role to a user or Service Account.

Configure Access Controls

Access controls can be configured on the Permissions screen and Accounts & Access screen in your Tecton cluster’s Web UI, located at https://<your Tecton instance prefix>.tecton.ai.

The Permissions screen contains a subset of the access control settings that are available on the Accounts & Access screen. See the next two sections for details.

The Permissions screen

The Permissions screen allows you to configure access controls for a specific workspace. To access this screen, select Permissions under the Workspaces section on the left side of the Web UI. After selecting Permissions, you will see a list of all users that have access to the workspace and the workspace roles each user has been granted. Selecting the Service Accounts tab will show you the same information for Service Accounts.

On the Permissions screen, you can perform the following tasks by following the steps specified in the second column.

Managing Service Accounts and role assignments with the CLI

The Tecton CLI additionally provides commands for creating and managing Service Accounts, and assigning or unassigning roles.

Service Account Management

To create, modify, and delete Service Accounts, use the tecton service-account command. Run tecton service-account --help for details on how to use the command.

Assigning and un-assigning access

To list, assign, or unassign a role from a principal, use the tecton access-control command. Run tecton access-control --help for details on how to use the command.

Authentication introspection

For convenience, you can also run the tecton whoami CLI command to inspect what principal is being used to authenticate the CLI.

User management using an identity provider

If you use an identity provider with Tecton (i.e. have SSO configured), just-in-time (JIT) provisioning occurs; the first time a user signs in to Tecton, a user account is created and the account appears on the Accounts & Access screen. If the user already had a Tecton account with the same email, signin via SSO signs the user in as the existing user. Each time the user signs in via their identity provider, the user's first and last name are also updated.

If a user is removed from your identity provider, the user account will still exist in Tecton, although that user will not be able to sign in, as they will be denied access by your identity provider. To completely remove the user from Tecton, delete the user from the Accounts & Access screen.

Tecton supports SSO using either SAML 2.0 or OpenID Connect (OIDC). Tecton is the Service Provider.

SSO with SAML

Tecton supports SSO with SAML 2.0. All common/standard Identity Providers that implement SAML 2.0 are supported. The standard set up supports:

• Service provider initiated (sp-initiated) SSO
• Identity provider initiated (idp-initiated) SSO
• Just in time (JIT) provisioning
• Request & response signing using SHA-256 signature algorithm
• Assertion Consumer Service HTTP-POST binding
• HTTP-redirect request binding
• Max clock skew of 2 minutes
• (available on request) assertion encryption

SAML uses the web browser for control flow so your identity provider can be on your corporate network as long as your users can access Tecton and your identity provider.

Configuring SSO with SAML

Single sign-on (SSO) enables your users to sign in to Tecton using your organization's Identity Provider for authentication. The process to set up SSO with SAML is:

1. Reach out to your account representative or support requesting SSO with SAML. If you have more than one Tecton instance, specify which instances you want to enable. They will provide you with the SAML Service Provider information for each of your Tecton instances. This includes:
   • Assertion Consumer Service URL: The Sign-on URL for sp-initiated SSO.
   • Entity ID: aka Audience URI
   • Default RelayState: This is passed as a query parameter and is the location to redirect the user after SSO (Not all IdPs support this parameter).
   • Public certificate: Used by your identity provider to verify the signature of sign-in requests were created by Tecton.
2. Create a SAML application for each Tecton instance in your Identity Provider using the provided configuration. Configure the SAML assertion's NameID to be the user's email. Also include claims for email, firstName, lastName, and optionally groups with these names. If unable to use these names, let us know the names for these claims. See below for examples of this with common identity providers.
3. Provide support the metadata for your identity provider (your identity provider may provide an option to export a xml file with this information). Please include:
   • Issuer: The id of your Identity Provider. Aka Entity ID.
   • IdP SSO URL: The binding-specific IdP Authentication Request Protocol endpoint that receives SAML AuthnRequest messages from Tecton.
   • Destination: The value of the destination field in the SAML Authentication Request (often the same as the IdP SSO URL).
   • Certificate: The public certificate used to verify the signature of assertions signed by your IdP.
4. Support will confirm when SSO is ready in Tecton, adding a "Sign in with SSO" button to the Tecton login screen. When you sign in via SSO, you should enter as your existing user (the email from the SAML is matched to your existing Tecton user's email). Sign out of Tecton and sign in via SSO to confirm SSO is working as expected.
5. At this point your users can sign in via SSO or their original Tecton-managed credentials. Please let support know if you wish to prevent sign in via Tecton-managed credentials. They will prevent tecton-managed username/password authentication for your users and remove the username/password fields from the login page.

Example With Okta

Follow these instructions for setting up SSO to Tecton if you use Okta as your Identity Provider.

For this example, we'll use the following data as though it was provided by Tecton support for your Tecton instance:

      • Or, from you IdP's Apps Dashboard (e.g. https://myapps.microsoft.com/), click the tile for your Tecton application.

Group management using an identity provider

Group memberships in Tecton can be managed by your Identity Provider. Tecton updates group memberships by matching group information provided by your Identity Provider during SAML-based single sign-on (SSO) with values configured on each group.

To have your Identity Provider manage group memberships:

1. Ensure your users sign in to Tecton via single sign-on (SSO) with SAML.
2. Configure your Identity Provider to include a groups attribute in the SAML assertion with attribute values that will be used to map to Tecton groups. Typically, this means passing through a subset of the groups defined in your Identity Provider (If using Okta, see Okta's Define group attribute statements docs for details).
3. Configure each group in Tecton (on the group's details page in the Accounts & Access screen) with the groups attribute values that map to the group. Matching any value is sufficient to map a user to the group.

Each time a user signs in via SSO with SAML, the user's group memberships update based upon whether the user's SAML's groups attribute values match any of a group's identity provider groups mapping values.

• If a new match is made, the user is added to the group. For new matches or if the user was previously manually added to the group, the group membership becomes managed by identity provider groups mappings.
• If a previous match no longer exists, the user is removed from the group.
• Manually created group memberships are preserved.

Identity provider groups mapping example

Consider a company with several teams that use Tecton and each of these has a group in their Identity Provider:

• Platform
• Fraud

If they want everyone to have the Viewer role, the Platform team to have Operator and the Fraud team to have Consumer, then they could define these principal groups:

Group Name	Role	Identity Provider Groups Mapping
Everyone	Viewer (on all workspaces)	Platform & Fraud
Operations	Operator (on all workspaces)	Platform
ML Engineers	Consumer (on prod workspace)	Fraud

Now imagine some users sign-in via SSO with SAML with different group information from their Identity Provider, they would be added to the following Tecton groups:

Person	Identity Provider groups values	Tecton group memberships
Alice	Platform	Everyone & Operations
Sienna	Fraud	Everyone & ML Engineers
Isabel	Platform & Fraud	Everyone, Operations & ML Engineers

Now imagine Alice moves from the Platform team to the Fraud team. On their next sign-in to Tecton, their group memberships would change: they would be removed from Operations and added to ML Engineers. Group memberships would then be:

Person	Identity Provider groups values	Tecton group memberships
Alice	Fraud	Everyone & ML Engineers
Sienna	Fraud	Everyone & ML Engineers
Isabel	Platform & Fraud	Everyone, Operations & ML Engineers

Below is a snippet showing how the group information should be passed in the SAML for a user with both the Platform & Fraud identity provider group attribute values. Note that each value must have its own AttributeValue tag.

<saml2:Attribute Name="groups" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:unspecified">
    <saml2:AttributeValue>Platform</saml2:AttributeValue>
    <saml2:AttributeValue>Fraud</saml2:AttributeValue>
</saml2:Attribute>

Best practices for configuring access controls

Use Principal Groups for managing access

Create principal groups with different access levels. For example, create an admin group for your Tecton administrators, and then grant it the admin role. Or create a group for a team of users with access granted on a set of workspaces. Grant the group a role on a new workspace, and all users in the group will inherit this role on the new workspace.

The moment a member is removed from the group, they immediately lose access to the roles and permissions they inherited from the group membership. They may still have access to the workspace via a role directly assigned to them.

Leverage your Identity Provider's data for group management

Take advantage of the groups that exist in your identity provider and map them to groups in Tecton (See: Group management using an identity provider). With Identity Provider groups mappings, group memberships can be setup for new users OOTB so they have the access then need on first-login to Tecton. By leveraging your Identity Provider for group membership changes in Tecton, your existing internal controls for access grants can be followed.

Use caution when granting Owner or Editor role to live workspaces

A principal with Owner or Editor roles can take actions in a workspace that can impact a production system. For example, running tecton apply on a workspace causes the workspace objects that were modified or removed to be deleted and replaced with the objects that are being applied.

Typically the Editor role will only be granted to the Service Account used for CI/CD, as well as a limited number of team members in case there is a need to apply directly.

Users and service accounts who do not need to tecton apply should be granted either the Viewer role, to view the workspace and metadata, or the Operator role, to also manage materialization jobs.

Use development workspaces for feature development

Feature development should be done in development workspaces. The developer should verify the transformation logic works as intended before promoting the feature to a production workspace.

Setting an API Key in a notebook

By default, the Tecton SDK will look for a Tecton API key in the secrets manager for your data platform. This default is suitable if you want uniform Notebook access for all users.

Use the tecton.set_credentials() method to explicitly set the API key for your session. Retrieve this API key from a secrets manager to avoid pasting it in plain text in your notebook.

Limitations

Offline materialized feature access depends on AWS or Snowflake roles

Accessing offline materialized feature data with the Tecton SDK depends on both Tecton and underlying storage permissions. Accessing feature data without the Tecton SDK can be done with only permissions to the underlying feature storage.

The principal must have at least the Viewer role on the relevant workspace to run commands that access offline materialized data, such as FeatureService.get_historical_features(). To restrict a user's offline materialized data access to specific workspaces, see configuring offline store access per workspace.

For Tecton on Databricks or EMR, access to offline feature data depends on the instance profile for the notebook cluster having access to the Tecton S3 bucket created during deployment.

For Tecton on Snowflake, access to offline feature data depends on the user’s access to the Tecton database created during deployment.

Workspace objects, such as data sources and feature views, cannot be shared between workspaces

If you set up separate workspaces for different teams, they will not be able to share objects in these workspaces. You can however use the same object definitions in multiple workspaces.
