Half of 4 Million Public Docker Hub Images Found to Have - InfoQ This shows that the risk of running outdated software as a result of images pulled from Docker Hub is high, but it can be reduced by choosing reliable publishers who keep their images up to date and by having policies in place that require vulnerability scanning and configuration analysis of Docker images at the time of deployment, as well as at regular intervals. feature that provides more in-depth results and guided remediation steps for If the image has security findings and is pulled, it will expose security vulnerabilities. The following table lists Docker Official Images that Based on that, automate the rebuild of images if necessary. While every organizations specific security needs form a unique and complex blend of interconnected requirements, numerous security fundamentals almost always apply to each of these groups. The breakdown by Docker image for vulnerability severity is as follows: We can see that, although there is variation between the individual Docker images, there is a general trend for the majority of the vulnerabilities to be low severity. Consider the following best practices when rebuilding an image: For detailed best practices and methods for building efficient images, see development and unit testing and the second for testing during the latest --no-cache to avoid cache hits and to ensure a fresh download. 2023 TechnologyAdvice.
