Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security measures are tailored to each specific system configuration, then security effectiveness is improved, but development time and cost increase
Solution Approach 1:
The patent creates a standardized security measure template that can be copied and applied to different system configurations. The template includes predefined security requirements, measures, and evaluation criteria that can be reused across multiple systems, reducing development time while maintaining effectiveness through systematic adaptation to specific system characteristics
Solution Approach 2:
The patent enables customization of security measures by changing parameters such as system requirements, threat levels, and measure priorities within the standardized template framework. This allows the same template to be adapted to different system configurations by adjusting parameters rather than creating entirely new security measures from scratch
2Reliability
If security measures are tailored to each specific system configuration, then security effectiveness is improved, but cost increases
Solution Approach 1:
By creating a reusable security measure template, the patent eliminates the need to develop security measures from scratch for each system. The template can be copied and adapted to multiple systems, significantly reducing development costs while maintaining security effectiveness through systematic customization
Solution Approach 2:
The patent develops a universal security measure template that can be applied to multiple different system configurations. This multi-functional approach allows a single template to serve various system types by adjusting parameters, reducing overall development costs across multiple security projects
3Reliability
If comprehensive security measures are implemented, then security effectiveness is improved, but system complexity increases
Solution Approach 1:
The patent segments comprehensive security measures into modular components within the template structure. Each security measure is broken down into discrete, manageable elements that can be independently selected, evaluated, and implemented based on specific system requirements, reducing overall system complexity while maintaining comprehensive security coverage
Solution Approach 2:
The patent applies different levels of security measures to different parts of the system based on local requirements and threat assessments. The template enables customization of security intensity for specific system components, ensuring comprehensive security where needed while avoiding unnecessary complexity in less critical areas

AI summary
According to one embodiment, an information processing device ranks one or more security measures technologies to be ranked. The information processing device includes processing circuitry configured to operate as an influence information obtaining unit, a requirements information obtaining unit and a ranking unit. The influence information obtaining unit obtains influence information indicating correspondence between the one or more security measures technologies and an influence on a system when each of the one or more security measures technologies is introduced into the system. The requirements information obtaining unit obtains requirements information indicating system requirements of the system. The ranking unit ranks the one or more security measures technologies based on a degree of satisfaction of the system requirements indicated in the requirements information, using the requirements information and the influence information.
