# aws\_iam\_groups
|
|
|

Use the `aws_iam_groups` Chef InSpec audit resource to test properties of all or multiple groups.
|
|
|
|
To test properties of a single group, use the `aws_iam_group` resource.
|
|

|
## 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_groups` resource block uses an optional filter to select a collection of IAM groups and then tests that collection.
|
|
|
|
# The control will pass if the filter returns at least one result. Use `should_not` if you expect zero matches.
|
|
describe aws_iam_groups do
|
|
it { should exist }
|
|
end
|
|
|
|
<br>
|
|
|
|
## Examples
|
|
|
|
The following examples show how to use this Chef InSpec audit resource.
|
|
|
|
As this is the initial release of `aws_iam_groups`, its limited functionality precludes examples.

|
## Filter Criteria
|
|
|
|
### group_name
|
|
|
|
Filters the IAM groups by their group name, a string. If you know the exact group name, use `aws_iam_group` (singular) instead. This criteria may be used when you know a pattern of the name.
|
|
|
|
# Use a regex to find groups ending with 'Admins'
|
|
describe aws_iam_groups.where(group_name: /Admins$/) do
|
|
its('group_names') { should include 'FriendlyAdmins' }
|
|
its('group_names') { shoud_not include 'ShunnedAdmins' }
|
|
end
|
|
|
|
## Properties
|
|
|
|
### group_names
|
|
|
|
An Array of Strings, reflecting the IAM group names matched by the filter. If no groups matched, this will be empty. You can also use this with `aws_iam_group` to enumerate groups.
|
|
|
|
# Check for friendly people
|
|
describe aws_iam_groups.where(group_name: /Admins$/) do
|
|
its('group_names') { should include 'FriendlyAdmins' }
|
|
its('group_names') { should include 'KindAdmins' }
|
|
end
|
|
|
|
# Use to loop and fetch groups individually for auditing in detail
|
|
# Without a `where`, this fetches all groups
|
|
aws_iam_groups.group_names.each do |group_names|
|
|
# A roundabout way of saying "bob should not be in any groups"
|
|
describe aws_iam_group(group_name) do
|
|
its('users') { should_not include 'bob' }
|
|
end
|
|
end
|
|
|
|

|

### exists
|
|
|
|
The control will pass if the filter returns at least one result. Use `should_not` if you expect zero matches.
|
|
|
|
describe aws_iam_groups
|
|
it { should exist }
|
|
