AWS Config

Config Service Not Enabled

This plugin ensures the AWS Config Service is enabled to detect changes to account resources.

Risk Level: Low

Description

This plugin ensures the AWS Config Service is enabled to detect changes to account resources. If the recorder is not configured for the region, AWS Config will not monitor or track any new configuration changes which are crucial in determining how a single change can affect other resources.

About the Service

AWS Config: AWS Config simplifies assessment, auditing and evaluation of the AWS resources’ configurations. It provides a detailed report on the relationship between various AWS resources based on their configuration. Apart from monitoring, AWS Config also determines the overall compliance based on the settings specified in your internal policies.

Impact

If the option is not enabled to record changes, critical configuration changes for all AWS services will not be recorded by AWS Config. In order to have complete visibility of your configuration changes, it is recommended to activate config recorders. Incorrect configurations can lead to exposing sensitive information globally.

  1. Log In to your AWS Console.
  2. Open the AWS Config console. You can use this link (https://console.aws.amazon.com/config) to navigate directly if already logged in.
