Using minimal base images enhances security by reducing potential vulnerabilities primarily because they contain only the essential components required to run an application. This slimmed-down approach limits the attack surface since fewer software packages, services, and configurations are present, thus minimizing the number of potential entry points for attackers. With fewer elements included in the image, there are also fewer opportunities for bugs or vulnerabilities to exist. Additionally, maintaining and updating a minimal base image can be easier and more efficient, allowing for quicker patching of any discovered vulnerabilities. This practice aligns with security best practices within the DevOps realm, encouraging the use of the least privilege model where only necessary components are included. In contrast, public base images may include unnecessary tools or libraries that could introduce security risks. Customized images, while potentially beneficial for specific applications, often inherit vulnerabilities from their base. All-in-one images tend to be bulky and can introduce a larger number of components, which increases complexity and potential security issues.
