Amazon Verified Permissions¶

Description¶

Amazon Verified Permissions is a permissions management service from Amazon Web Services. You can use Verified Permissions to manage permissions for your application, and authorize user access based on those permissions. Using Verified Permissions, application developers can grant access based on information about the users, resources, and requested actions. You can also evaluate additional information like group membership, attributes of the resources, and session context, such as time of request and IP addresses. Verified Permissions manages these permissions by letting you create and store authorization policies for your applications, such as consumer-facing web sites and enterprise business systems.

Verified Permissions uses Cedar as the policy language to express your permission requirements. Cedar supports both role-based access control (RBAC) and attribute-based access control (ABAC) authorization models.

For more information about configuring, administering, and using Amazon Verified Permissions in your applications, see the Amazon Verified Permissions User Guide.

For more information about the Cedar policy language, see the Cedar Policy Language Guide.

When you write Cedar policies that reference principals, resources and actions, you can define the unique identifiers used for each of those elements. We strongly recommend that you follow these best practices:

Use values like universally unique identifiers (UUIDs) for all principal and resource identifiers.

For example, if user jane leaves the company, and you later let someone else use the name jane, then that new user automatically gets access to everything granted by policies that still reference User::"jane". Cedar can’t distinguish between the new user and the old. This applies to both principal and resource identifiers. Always use identifiers that are guaranteed unique and never reused to ensure that you don’t unintentionally grant access because of the presence of an old identifier in a policy.

Where you use a UUID for an entity, we recommend that you follow it with the // comment specifier and the ‘friendly’ name of your entity. This helps to make your policies easier to understand. For example: principal == User::"a1b2c3d4-e5f6-a1b2-c3d4-EXAMPLE11111", // alice
Do not include personally identifying, confidential, or sensitive information as part of the unique identifier for your principals or resources. These identifiers are included in log entries shared in CloudTrail trails.

Several operations return structures that appear similar, but have different purposes. As new functionality is added to the product, the structure used in a parameter of one operation might need to change in a way that wouldn't make sense for the same parameter in a different operation. To help you understand the purpose of each, the following naming convention is used for the structures:

Parameter type structures that end in Detail are used in Get operations.
Parameter type structures that end in Item are used in List operations.
Parameter type structures that use neither suffix are used in the mutating (create and update) operations.

Usage¶

verifiedpermissions(
  config = list(),
  credentials = list(),
  endpoint = NULL,
  region = NULL
)

Arguments¶

config

Optional configuration of credentials, endpoint, and/or region.

credentials:
- creds:
  - access_key_id: AWS access key ID
  - secret_access_key: AWS secret access key
  - session_token: AWS temporary session token
- profile: The name of a profile to use. If not given, then the default profile is used.
- anonymous: Set anonymous credentials.
endpoint: The complete URL to use for the constructed client.
region: The AWS Region used in instantiating the client.
close_connection: Immediately close all HTTP connections.
timeout: The time in seconds till a timeout exception is thrown when attempting to make a connection. The default is 60 seconds.
s3_force_path_style: Set this to true to force the request to use path-style addressing, i.e. ⁠http://s3.amazonaws.com/BUCKET/KEY⁠.
sts_regional_endpoint: Set sts regional endpoint resolver to regional or legacy https://docs.aws.amazon.com/sdkref/latest/guide/feature-sts-regionalized-endpoints.html

credentials

Optional credentials shorthand for the config parameter

creds:
- access_key_id: AWS access key ID
- secret_access_key: AWS secret access key
- session_token: AWS temporary session token
profile: The name of a profile to use. If not given, then the default profile is used.
anonymous: Set anonymous credentials.

endpoint

Optional shorthand for complete URL to use for the constructed client.

region

Optional shorthand for AWS Region used in instantiating the client.

Value¶

A client for the service. You can call the service's operations using syntax like svc$operation(...), where svc is the name you've assigned to the client. The available operations are listed in the Operations section.

Service syntax¶

        session_token = "string"
      ),
      profile = "string",
      anonymous = "logical"
    ),
    endpoint = "string",
    region = "string",
    close_connection = "logical",
    timeout = "numeric",
    s3_force_path_style = "logical",
    sts_regional_endpoint = "string"
  ),
  credentials = list(
    creds = list(
      access_key_id = "string",
      secret_access_key = "string",
      session_token = "string"
    ),
    profile = "string",
    anonymous = "logical"
  ),
  endpoint = "string",
  region = "string"
)
