CloudFormation Validation

Description

This AWS CloudFormation solution deploys AWS Config, a service that enables you to assess, audit, and evaluate the configurations of your AWS resources. Config continuously monitors and records your AWS resource configurations and allows you to automate the evaluation of recorded configurations against desired configurations. The AWS CloudFormation template creates a AWS KMS encryption key for S3, and enables Config for the account.

Config data are stored in an encrypted (AES-256) S3 bucket that the CloudFormation template creates. For security and compliance it is important all AWS account activity is tracked and stored for tracking and analysis.

AWS Config

AWS CloudFormation provides a common language for you to describe and provision all the infrastructure resources in your cloud environment.

Using AWS Config, you can assess, audit, and evaluate the configurations of your AWS resources. Config continuously monitors and records your AWS resource configurations and allows you to automate the evaluation of recorded configurations against desired configurations. With Config, you can review changes in configurations and relationships between AWS resources, dive into detailed resource configuration histories, and determine your overall compliance against the configurations specified in your internal guidelines. This enables you to simplify compliance auditing, security analysis, change management, and operational troubleshooting.
