Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If container management systems are deployed on host platforms without sufficient protection, then ease of deployment is improved, but security reliability deteriorates allowing attackers to hack and compromise the system
Solution Approach 1:
The patent implements preliminary security measures by generating digital signatures for container images before they are deployed to host platforms. The security management system signs container images with cryptographic keys, creating verified container images that can be safely deployed without requiring additional protection measures at deployment time. This preliminary action ensures security reliability is established before deployment occurs.
Solution Approach 2:
The patent introduces a security management system as an intermediary between container image repositories and host platforms. This intermediary system verifies container images through digital signatures before they are deployed to host platforms, acting as a trusted mediator that ensures security without complicating the deployment process. The security management system mediates the trust relationship between image creators and deployment targets.
2Reliability
If digital signature verification is implemented for all container components, then security reliability is improved, but system complexity increases
Solution Approach 1:
The patent uses digital signatures as cryptographic copies of verification data that can be efficiently stored and checked. Instead of implementing complex real-time analysis of container components, the system creates simplified signature copies that represent the security state of container images, making verification straightforward and reducing system complexity while maintaining high security reliability.
3Reliability
If security verification is performed on container images before deployment, then security reliability is improved, but deployment time increases
Solution Approach 1:
The patent performs security verification through digital signature generation before container images are deployed to host platforms. By completing the verification action preliminarily during the image creation phase, the system ensures security reliability is established upfront, allowing for faster deployment since verification doesn't need to be repeated at deployment time. The preliminary signing action prevents time loss during actual deployment.
Data Source
AI summary
Examples described herein relate to a security management system to secure a container ecosystem. In some examples, the security management system may protect one or more entities such as container management applications, container images, containers, and/or executable applications within the containers. The security management system may make use of digital cryptography to generate digital signatures corresponding to one or more of these entities and verify them during the execution so that any compromised entities can be blocked from execution and the container ecosystem may be safeguarded from any malicious network attacks.
