Fields
deniedPrincipals[]

string

The identities that are prevented from using one or more permissions on Google Cloud resources. This field can contain the following values:

  • principal://goog/subject/{email_id}: A specific Google Account. Includes Gmail, Cloud Identity, and Google Workspace user accounts. For example, principal://goog/subject/alice@example.com.

  • principal://iam.googleapis.com/projects/-/serviceAccounts/{service_account_id}: A Google Cloud service account. For example, principal://iam.googleapis.com/projects/-/serviceAccounts/my-service-account@iam.gserviceaccount.com.

  • principalSet://goog/group/{groupId}: A Google group. For example, principalSet://goog/group/admins@example.com.

  • principalSet://goog/public:all: A special identifier that represents any principal that is on the internet, even if they do not have a Google Account or are not logged in.

  • principalSet://goog/cloudIdentityCustomerId/{customer_id}: All of the principals associated with the specified Google Workspace or Cloud Identity customer ID. For example, principalSet://goog/cloudIdentityCustomerId/C01Abc35.

  • principal://iam.googleapis.com/locations/global/workforcePools/{pool_id}/subject/{subject_attribute_value}: A single identity in a workforce identity pool.

  • principalSet://iam.googleapis.com/locations/global/workforcePools/{pool_id}/group/{groupId}: All workforce identities in a group.

  • principalSet://iam.googleapis.com/locations/global/workforcePools/{pool_id}/attribute.{attribute_name}/{attribute_value}: All workforce identities with a specific attribute value.

  • principalSet://iam.googleapis.com/locations/global/workforcePools/{pool_id}/*: All identities in a workforce identity pool.

  • principal://iam.googleapis.com/projects/{projectNumber}/locations/global/workloadIdentityPools/{pool_id}/subject/{subject_attribute_value}: A single identity in a workload identity pool.

  • principalSet://iam.googleapis.com/projects/{projectNumber}/locations/global/workloadIdentityPools/{pool_id}/group/{groupId}: A workload identity pool group.

  • principalSet://iam.googleapis.com/projects/{projectNumber}/locations/global/workloadIdentityPools/{pool_id}/attribute.{attribute_name}/{attribute_value}: All identities in a workload identity pool with a certain attribute.

  • principalSet://iam.googleapis.com/projects/{projectNumber}/locations/global/workloadIdentityPools/{pool_id}/*: All identities in a workload identity pool.

  • deleted:principal://goog/subject/{email_id}?uid={uid}: A specific Google Account that was deleted recently. For example, deleted:principal://goog/subject/alice@example.com?uid=1234567890. If the Google Account is recovered, this identifier reverts to the standard identifier for a Google Account.

  • deleted:principalSet://goog/group/{groupId}?uid={uid}: A Google group that was deleted recently. For example, deleted:principalSet://goog/group/admins@example.com?uid=1234567890. If the Google group is restored, this identifier reverts to the standard identifier for a Google group.

  • deleted:principal://iam.googleapis.com/projects/-/serviceAccounts/{service_account_id}?uid={uid}: A Google Cloud service account that was deleted recently. For example, deleted:principal://iam.googleapis.com/projects/-/serviceAccounts/my-service-account@iam.gserviceaccount.com?uid=1234567890. If the service account is undeleted, this identifier reverts to the standard identifier for a service account.

  • deleted:principal://iam.googleapis.com/locations/global/workforcePools/{pool_id}/subject/{subject_attribute_value}: Deleted single identity in a workforce identity pool. For example, deleted:principal://iam.googleapis.com/locations/global/workforcePools/my-pool-id/subject/my-subject-attribute-value.
exceptionPrincipals[]

string

The identities that are excluded from the deny rule, even if they are listed in the deniedPrincipals. For example, you could add a Google group to the deniedPrincipals, then exclude specific users who belong to that group.

This field can contain the same values as the deniedPrincipals field, excluding principalSet://goog/public:all, which represents all users on the internet.
deniedPermissions[]

string

The permissions that are explicitly denied by this rule. Each permission uses the format {service_fqdn}/{resource}.{verb}, where {service_fqdn} is the fully qualified domain name for the service. For example, iam.googleapis.com/roles.list.
exceptionPermissions[]

string

Specifies the permissions that this rule excludes from the set of denied permissions given by deniedPermissions. If a permission appears in deniedPermissions and in exceptionPermissions then it will not be denied.

The excluded permissions can be specified using the same syntax as deniedPermissions.
denialCondition

object (Expr)

The condition that determines whether this deny rule applies to a request. If the condition expression evaluates to true, then the deny rule is applied; otherwise, the deny rule is not applied.

Each deny rule is evaluated independently. If this deny rule does not apply to a request, other deny rules might still apply.

The condition can use CEL functions that evaluate resource tags. Other functions and operators are not supported.
