Basic roles

Basic roles are roles that existed prior to IAM. These roles have unique characteristics:

Basic roles can only be granted for an entire project, not for individual buckets within the project. Like other roles that you grant for a project, basic roles apply to all buckets and objects in the project.
Basic roles contain additional permissions for other Google Cloud services that are not covered in this section. See basic roles for a general discussion of the permissions that basic roles grant.
In some cases, basic roles can be used as if they were groups, which causes any principal that has the basic role to get additional access for some resources.
- A basic role can be used as if it were a group when granting roles for buckets.
- A basic role can be used as if it were a group when setting ACLs on objects.
For a discussion of additional access that principals with basic roles typically gain due to this behavior, see modifiable behavior.

Custom roles

You may wish to define your own roles which contain bundles of permissions that you specify. To support this, IAM offers custom roles.
