This is useful to restrict the Identity and Access Management (IAM) permissions that a short-lived credential can use. To downscope permissions of a source credential, a Credential Access Boundary that specifies which resources the new credential can access, as well as an upper bound on the permissions that are available on each resource, has to be defined. A downscoped credential can then be instantiated using the source credential and the Credential Access Boundary. The common pattern of usage is to have a token broker with elevated access generate these downscoped credentials from higher access source credentials and pass the downscoped short-lived access tokens to a token consumer via some secure authenticated channel for limited access to Google Cloud Storage resources. For example, a token broker can be set up on a server in a private network. Various workloads (token consumers) in the same network will send authenticated requests to that broker for downscoped tokens to access or modify specific google cloud storage buckets. The broker will instantiate downscoped credentials instances that can be used to generate short lived downscoped access tokens that can be passed to the token consumer. These downscoped access tokens can be injected by the consumer into google.oauth2.Credentials and used to initialize a storage client instance to access Google Cloud Storage resources with restricted access. Note: Only Cloud Storage supports Credential Access Boundaries. Other Google Cloud services do not support this feature. .. _Downscoping with Credential Access Boundaries: https://cloud.google.com/iam/docs/downscoping-short-lived-credentials N)_helpers) credentials) exceptions)sts z/urn:ietf:params:oauth:grant-type:token-exchangez-urn:ietf:params:oauth:token-type:access_tokenzhttps://sts.{}/v1/tokencZeZdZdZgfdZedZejdZdZdZ y)CredentialAccessBoundarya0Defines a Credential Access Boundary which contains a list of access boundary rules.
