A CI/CD pipeline builds container images, pushes them to Amazon ECR, and then deploys to an EKS development namespace for dynamic testing. The team wants to add an image analysis stage earlier in the pipeline to scan images before deploying to EKS. Which solution provides the most operational efficiency?

The most operationally efficient solution is to integrate image scanning directly into the CI/CD pipeline using AWS native services. Adding a CodePipeline stage after the image build allows ECR basic image scanning to run automatically when the image is pushed. A Lambda function can then be triggered to evaluate the scan results. If critical vulnerabilities are found, the Lambda can fail the pipeline, preventing the deployment of insecure images. This approach leverages ECR's built-in capabilities, automates the scanning process, and provides immediate feedback within the pipeline, minimizing manual intervention and ensuring security early in the development lifecycle. Building images locally and using pre-commit hooks is a good practice but doesn't guarantee all images pushed to ECR are scanned, as hooks can be bypassed. Scanning source code is important but doesn't address vulnerabilities introduced during the container image build process or in base images. Modifying the deployment stage to check scan results means the image has already been pushed and potentially made available, which is later in the process than desired for early detection.
