Install

This resource is available in the Chef InSpec AWS resource pack.

For information on configuring your AWS environment for Chef InSpec and creating an InSpec profile that uses the InSpec AWS resource pack, see the Chef InSpec documentation on the AWS cloud platform.

The aws_iam_managed_policies resource returns a collection of IAM managed policies and allows testing of that collection.

describe aws_iam_managed_policies do
  its('policy_names') { should include('POLICY_NAME') }
end

This resource allows filtering by scope, which are:

To list only AWS-managed policies, set scope to AWS.
To list only the customer-managed policies in your AWS account, set scope to Local.
If a scope is not provided or if scope is set to ALL, all policies are returned.

describe aws_iam_managed_policies(scope: 'AWS') do
  it { should exist }
end

describe aws_iam_managed_policies(scope: 'Local') do
  it { should exist }
end

describe aws_iam_managed_policies(scope: 'ALL') do
  it { should exist }
end

scope (optional)

scope accepts three possible values, AWS, Local, or ALL:

: Specify a scope by passing a key-value entry in a hash: scope: 'VALUE'.: If ommitted, all policies are returned.

arns: A list of the ARN identifiers of the policies.; Field: arn
policy_ids: A list of the stable and unique strings identifying the policies.; Field: policy_id
policy_names: A list of the friendly names (not ARN) identifying the policies.; Field: policy_name
attachment_counts: A list of the counts of attached entities for each policy.; Field: attachment_count
attached_groups: A list of the list of group names of the groups attached to each policy.; Field: attached_group
default_version_ids: A list of the identifier for the default version of the policy.; Field: default_version_id

Ensure a specific policy exists.

describe aws_iam_managed_policies do
  its('policy_names') { should include('POLICY_NAME') }
end

Allow at most 100 IAM Policies on the account.

describe aws_iam_managed_policies do
  its('polict_ids.count') { should be <= 100}
end

For a full list of available matchers, visit the InSpec matchers page.

The control passes if the describe returns at least one result.

Use should to test the entity should exist.

describe aws_iam_managed_policies.where( PROPERTY: PROPERTY_VALUE) do
  it { should exist }
end

Use should_not to test the entity should not exist.

describe aws_iam_managed_policies.where( PROPERTY: PROPERTY_VALUE) do
  it { should_not exist }
end

Your Principal will need the iam:ListPolicies action with Effect set to Allow.
