Quick Summary
Docker has made more than 1,000 Docker Hardened Images (DHI) freely available under the Apache 2.0 license. These images, launched in May, are designed to reduce security risks and are maintained by Docker. This move aims to provide a secure, minimal foundation for over 26 million developers in the container ecosystem.
The Securityish Brief
Docker has transitioned its Docker Hardened Images (DHI) from a commercial offering to a subscription-free model, making them open source as of October. This change allows developers to access a catalog of over 1,000 secure, production-ready images that are rootless and free of known vulnerabilities. The DHIs support the Vulnerability Exploitability eXchange (VEX) standard, which aids in security management.
While the DHI images are available for free, Docker maintains a commitment to push fixes for newly disclosed flaws within seven days for its commercial tier, DHI Enterprise. This tier also allows for modifications and additional configurations, aiming to reduce the time to fix flaws to one day or less.
The decision to make DHIs freely available is significant for the developer community, as it establishes a new industry standard for secure container images. By providing a foundation that is both minimal and secure, Docker is addressing supply-chain risks at the container layer.
For everyday users and organizations, this move highlights the importance of using secure base images in application development. Developers should consider leveraging these hardened images to enhance their security posture and reduce potential vulnerabilities in their applications.
As the cybersecurity landscape evolves, the availability of these open-source images can help organizations mitigate risks associated with containerization. It is crucial for teams to stay informed about the security features and updates provided by Docker for these images.
