Actions Defined by AWS Security Token Service
You can specify the following actions in the Action
element of an IAM policy statement. Use policies to grant permissions to perform
an operation in AWS. When you use an action in a policy, you usually allow or
deny access to the API operation or CLI command with the same name. However,
in some cases, a single action controls access to more than one operation. Alternatively,
some operations require several different actions.
The Resource column indicates whether each action supports resource-level permissions. If
there is no value for this column, you must specify all resources ("*") in the
Resource
element of your policy statement. If the column includes a resource type, then
you can specify an ARN of that type in a statement with that action. Required
resources are indicated in the table with an asterisk (*). If you specify a resource-level
permission ARN in a statement using this action, then it must be of this type.
Some actions support multiple resource types. If the resource type is optional (not
indicated as required), then you can choose to use one but not the other.
For details about the columns in the following table, see The Actions Table.

Resources Defined by AWS Security Token Service
The following resource types are defined by this service and can be used in the
Resource
element of IAM permission policy statements. Each action in the Actions table identifies the resource types that can be specified with that action. A resource
type can also define which condition keys you can include in a policy. These
keys are displayed in the last column of the table. For details about the columns
in the following table, see The Resource Types Table.
Condition Keys for AWS Security Token Service
AWS Security Token Service defines the following condition keys that can be used in
the Condition
element of an IAM policy. You can use these keys to further refine the conditions
under which the policy statement applies. For details about the columns in the
following table, see The Condition Keys Table.
