Ensure AWS Config is enabled in all regions

Severity: Medium

Resource Types: AWS::ConfigService::ConfigurationRecorder

Description​

AWS Config is a web service that performs configuration management of supported AWS resources in your account and delivers log files to you. The recorded information includes the configuration item (AWS resource), relationships between configuration items (AWS resources), and any configuration changes between resources.

The AWS configuration item history captured by AWS Config enables security analysis, resource change tracking, and compliance auditing.
