aws_config_delivery_channel resource

[edit on GitHub]

The AWS Config service can monitor and record changes to your AWS resource configurations. A Delivery Channel can record the changes to an S3 Bucket, an SNS or both.

Use the aws_config_delivery_channel InSpec audit resource to examine how the AWS Config service delivers those change notifications.

One delivery channel is allowed per region per AWS account, and the delivery channel is required to use AWS Config.

Syntax

describe aws_config_delivery_channel('my_channel') do
  it { should exist }
end

describe aws_config_delivery_channel(channel_name: 'my-channel') do
  it { should exist }
end

Since you may only have one Delivery Channel per region, and InSpec connections are per-region, you may also omit the channel_name to obtain the one Delivery Channel (if any) that exists:

    describe aws_config_delivery_channel do
      it { should exist }
    end

Parameters

channel_name (optional)

This resource can be passed a single parameter, the Channel Name. This can be passed either as a string or as a channel_name: 'value' key-value entry in a hash.

See also the AWS documentation on Delivery Channels.

Properties

Property Description
channel_name The name of the delivery channel. By default, AWS Config assigns the name “default” when creating the delivery channel.
s3_bucket_name The name of the Amazon S3 bucket to which AWS Config delivers configuration snapshots and configuration history files.
s3_key_prefix The prefix for the specified Amazon S3 bucket.
sns_topic_arn The Amazon Resource Name (ARN) of the Amazon SNS topic to which AWS Config sends notifications about configuration changes.
delivery_frequency_in_hours Specifies how often the AWS Config sends configuration changes to the s3 bucket in the delivery channel.

Examples

Test how frequently the channel writes configuration changes to the s3 bucket

describe aws_config_delivery_channel(channel_name: 'my-recorder') do
  its('delivery_frequency_in_hours') { should be > 3 }
end

Ensure configuration change notifications are being delivered to the correct bucket and key

describe aws_config_delivery_channel(channel_name: 'my_channel')
  its('s3_bucket_name') { should eq 'my_bucket' }
  its('s3_key_prefix')  { should eq 'logs/' }
end

Matchers

exist

The control will pass if the describe returns at least one result.

Use should_not to test the entity should not exist.

describe aws_config_delivery_channel('my_channel') do
  it { should exist }
end

describe aws_config_delivery_channel('my-nonexistent-channel') do
  it { should_not exist }
end

AWS Permissions

Your Principal will need the config:DescribeDeliveryChannels action with Effect set to Allow.

You can find detailed documentation at Actions, Resources, and Condition Keys for AWS Config.
