title: About the aws_iam_policies Resource

# aws\_iam\_policies
|
|
|
|
Use the `aws_iam_policies` Chef InSpec audit resource to test properties of some or all AWS IAM Policies.
|
|
|
|
A policy is an entity in AWS that, when attached to an identity or resource, defines their permissions. AWS evaluates these policies when a principal, such as a user, makes a request. Permissions in the policies determine if the request is allowed or denied.
|
|
|
|
Each IAM Policy is uniquely identified by either its `policy_name` or `arn`.

## Availability
|
|
|
|
### Installation
|
|
|
|
This resource is distributed along with Chef InSpec itself. You can use it automatically.
|
|
|
|
### Version
|
|
|
|
This resource first became available in v2.0.16 of InSpec.
|
|
|
|
## Syntax
|
|
|
|
An `aws_iam_policies` resource block collects a group of IAM Policies and then tests that group.
|
|
|
|
# Verify the policy specified by the policy name is included in IAM Policies in the AWS account.
|
|
describe aws_iam_policies do
|
|
its('policy_names') { should include('test-policy-1') }
|
|
end
|
|
|
|
<br>
|
|
|
|
## Examples
|
|
|
|
The following examples show how to use this Chef InSpec audit resource.
|
|
|
|
As this is the initial release of `aws_iam_policies`, its limited functionality precludes examples.
