When an image is pushed to Amazon ECR, it can be automatically scanned for vulnerabilities using the Common Vulnerabilities and Exposures (CVEs) database, which is managed and updated by the open source community. Users can review the scan findings and prioritize the necessary actions to mitigate potential security risks. This helps in maintaining a secure and compliant container image repository.
Guide to Image Scanning in Amazon ECR
What is it? Image scanning in Amazon Elastic Container Registry (ECR) is a feature that helps in identifying software vulnerabilities in your Docker images. It works by comparing the packages included in the image against a database of known vulnerabilities.
Why is it important? With Image Scanning, you can prevent deploying containers that would put your environment at risk, indicating security loopholes before application is exposed to live traffic. This is crucial for ensuring security of your applications in the Amazon ECR.
How does it work? When you push an image into ECR, Amazon can automatically scan it for vulnerabilities. It uses the Common Vulnerabilities and Exposures (CVEs) database from the open-source Clair project to identify any known issues in the software packages included in your image.
Exam Tips: Answering Questions on Image Scanning 1. Understand the purpose and functionality of Image Scanning in AWS. 2. Remember that image scanning happens every time an image is pushed to the Amazon ECR. 3. Being a best practice, do not disable the Image Scanning feature. 4. Familiarize yourself with how image scan findings are presented in the ECR console. 5. Identified vulnerabilities are compared against the CVEs database. 6. Understand that although image scanning is automated, acting on its findings (e.g., patching an image) is a manual process.
