Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If integrated web security solutions with API protection are introduced, then security coverage against API attacks is improved, but device complexity and implementation burden increase
Solution Approach 1:
The patent combines web application firewall (WAF) functions with API security protection into a single integrated security device. The device simultaneously handles HTTP/HTTPS traffic inspection and API request validation, merging previously separate security functions into one unified system that reduces implementation complexity while maintaining comprehensive security coverage.
Solution Approach 2:
The security device is designed to perform multiple functions including web application firewall operations, API security protection, bot mitigation, and DDoS defense within a single platform. This multi-functional approach allows organizations to deploy one universal security solution rather than multiple separate tools, reducing overall system complexity.
2Reliability
If hash verification tool is deployed for API security, then API attack detection capability is improved, but system resource consumption increases
Solution Approach 1:
The system performs preliminary actions by pre-registering API specifications, endpoints, and authentication methods in the hash verification tool before actual API traffic arrives. This advance preparation creates ready-to-use verification rules that enable rapid real-time validation without requiring intensive computational resources during live traffic processing.
Solution Approach 2:
The patent replaces complex manual API security verification processes with automated hash-based validation mechanisms. Instead of requiring intricate rule-based inspection of each API request, the system uses cryptographic hash verification to efficiently authenticate API endpoints and parameters, significantly reducing computational overhead.
3Reliability
If comprehensive API security verification is performed, then security against data breaches is improved, but processing time for legitimate requests increases
Solution Approach 1:
The security verification process applies different levels of inspection to different parts of API traffic. Critical authentication parameters and sensitive data fields receive rigorous hash verification, while non-critical request elements undergo lighter validation. This differentiated approach maintains strong security against data breaches while minimizing processing time for legitimate requests.

AI summary
Disclosed is a security method for client application programming interface (API) security that is performed by a security device including a service provider and a hash verification tool. The security method may comprise: registering, by the service provider, the API in the hash verification tool; storing, by the hash verification tool, the API, an identifier (ID) of the API, and a hash; and transmitting, by the hash verification tool, the ID and the hash to the service provider.
