Access control with IAM

This page describes the Identity and Access Management (IAM) roles required to configure VPC Service Controls.

Required roles

The following table lists the permissions and roles required to create and list access policies:

Action Required permissions and roles

Create an organization-level access policy or scoped policies

Action	Required permissions and roles
Create an organization-level access policy or scoped policies	Permission: `accesscontextmanager.policies.create` Role that provides the permission: Access Context Manager Editor role (`roles/accesscontextmanager.policyEditor`)
List an organization-level access policy or scoped policies	Permission: `accesscontextmanager.policies.list` Roles that provides the permission: Access Context Manager Editor role (`roles/accesscontextmanager.policyEditor`) Access Context Manager Reader role (`roles/accesscontextmanager.policyReader`)

Permission: accesscontextmanager.policies.create

Role that provides the permission: Access Context Manager Editor role (roles/accesscontextmanager.policyEditor)

List an organization-level access policy or scoped policies

Permission: accesscontextmanager.policies.list

Roles that provides the permission:

Access Context Manager Editor role (roles/accesscontextmanager.policyEditor)
Access Context Manager Reader role (roles/accesscontextmanager.policyReader)

You can only create, list, or delegate scoped policies if you have those permissions at the organization level. After you create a scoped policy, you can grant permission to manage the policy by adding IAM bindings on the scoped policy.

Permissions granted at the organization-level apply to all access policies, including the organization-level policy and any scoped policies.

The following predefined IAM roles provide the necessary permissions to view or configure service perimeters and access levels:

Access Context Manager Admin (roles/accesscontextmanager.policyAdmin)
Access Context Manager Editor (roles/accesscontextmanager.policyEditor)
Access Context Manager Reader (roles/accesscontextmanager.policyReader)

To grant one of these roles, use the Google Cloud console or run one of the following commands in the gcloud CLI. Replace ORGANIZATION_ID with the ID of your Google Cloud organization.
