Using the Amazon Verified Permissions test bench - Amazon Verified Permissions

Using the Amazon Verified Permissions test bench

Use the Verified Permissions test bench to test and troubleshoot Verified Permissions policies by running authorization requests against them. The test bench uses the parameters that you specify to determine whether the Cedar policies in your policy store would authorize the request. You can toggle between Visual mode and JSON mode while testing authorization requests. For more information about how Cedar policies are structured and evaluated, see Basic policy construction in Cedar in the Cedar policy language Reference Guide.

Note

When you make an authorization request using Verified Permissions, you can provide the list of principals and resources as part of the request in the Additional entities section. However, you can't include the details about the actions. They must be specified in the schema or inferred from the request. You can't put an action in the Additional entities section.

For a visual overview and demonstration of the test bench, see Amazon Verified Permissions - Policy Creation and Testing (Primer Series #3) on the AWS YouTube channel.

Visual mode
Note

You must have a schema defined in your policy store to use the Visual mode of the test bench.

To test policies in Visual mode

  1. Open the Verified Permissions console. Choose your policy store.

  2. In the navigation pane on the left, choose Test bench.

  3. Choose Visual mode.

  4. In the Principal section, choose the Principal taking action from the principal types in your schema. Type an identifier for the principal in the text box.

  5. (Optional) Choose Add a parent to add parent entities for the specified principal. To remove a parent that has been added to the principal, choose Remove next to the name of the parent.

  6. Specify the Attribute value for each attribute of the specified principal. The test bench uses the specified attribute values in the simulated authorization request.

  7. In the Resource section, choose the Resource that principal is acting on. Type an identifier for the resource in the text box.

  8. (Optional) Choose Add a parent to add parent entities for the specified resource. To remove a parent that has been added to the resource, choose Remove next to the name of the parent.

  9. Specify the Attribute value for each attribute of the specified resource. The test bench uses the specified attribute values in the simulated authorization request.

  10. In the Action section, choose the Action that principal is taking from the list of valid actions for the specified principal and resource.

  11. Specify the Attribute value for each attribute of the specified action. The test bench uses the specified attribute values in the simulated authorization request.

  12. (Optional) In the Additional entities section, choose Add entity to add entities to be evaluated for the authorization decision.

  13. Choose the Entity Identifier from the dropdown list and type the entity identifier.

  14. (Optional) Choose Add a parent to add parent entities for the specified entity. To remove a parent that has been added to the entity, choose Remove next to the name of the parent.

  15. Specify the Attribute value for each attribute of the specified entity. The test bench uses the specified attribute values in the simulated authorization request.

  16. Choose Confirm to add the entity to the test bench.

  17. Choose Run authorization request to simulate the authorization request for the Cedar policies in your policy store. The test bench displays the decision to allow or deny the request along with information about the policies satisfied or the errors encountered during evaluation.

JSON mode
To test policies in JSON mode

  1. Open the Verified Permissions console. Choose your policy store.

  2. In the navigation pane on the left, choose Test bench.

  3. Choose JSON mode.

  4. In the Request details section, if you have a schema defined, choose the Principal taking action from the principal types in your schema. Type an identifier for the principal in the text box.

    If you do not have a schema defined, type the principal in the Principal taking action text box.

  5. If you have a schema defined, choose the Resource from the resource types in your schema. Type an identifier for the resource in the text box.

    If you do not have a schema defined, type the resource in the Resource text box.

  6. If you have a schema defined, choose the Action from the list of valid actions for the specified principal and resource.

    If you do not have a schema defined, type the action in the Action text box.

  7. Enter the context of the request to simulate in the Context field. The request context is additional information that can be used for authorization decisions.

  8. In the Entities field, enter the hierarchy of the entities and their attributes to be evaluated for the authorization decision.

  9. Choose Run authorization request to simulate the authorization request for the Cedar policies in your policy store. The test bench displays the decision to allow or deny the request along with information about the policies satisfied or the errors encountered during evaluation.
