CI/CD Integration for CloudFormation Security

CI/CD Integration for CloudFormation Security

Pipeline security validation ensures every CloudFormation template undergoes security review before deployment. Integrate static analysis tools like cfn-lint and CloudFormation Guard into CI/CD pipelines. Use AWS CodePipeline with Lambda functions to implement custom security validations specific to organizational requirements.

Change set reviews provide a critical security checkpoint before infrastructure modifications. CloudFormation change sets show exactly what resources will be created, modified, or deleted. Security teams can review change sets for potential security impacts before execution. Automated change set analysis can flag high-risk changes for manual review.
