Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If software containers allow access to host ports for network connectivity, then the application can communicate with external networks, but the application becomes vulnerable to external malicious entities

Engineering Contradiction:

Improvenetwork connectivityVSAvoidvulnerability to malicious entities

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a security intermediary layer that sits between the containerized application and the host network ports. This intermediary monitors and controls network traffic, allowing legitimate communication while blocking malicious entities. The security layer acts as a mediator that preserves network connectivity while filtering out harmful factors before they reach the application.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements preliminary security measures by scanning container configurations before deployment to identify exposed ports and potential vulnerabilities. Security policies are established in advance, and the system proactively blocks malicious traffic before it can exploit vulnerabilities, rather than reacting after an attack occurs.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If applications are configured to expose ports for external access, then network functionality is enabled, but exposure vulnerabilities occur due to incorrect configurations

Engineering Contradiction:

Improvenetwork functionalityVSAvoidconfiguration security

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements a feedback mechanism that continuously monitors container port configurations and compares them against security policies. When misconfigurations are detected, the system provides feedback to administrators and automatically remediates issues by blocking vulnerable ports or adjusting firewall rules, ensuring configuration security is maintained alongside network functionality.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs self-service security hardening by automatically scanning container configurations, identifying exposed ports, and applying security policies without requiring manual intervention. The platform autonomously detects and remediates configuration vulnerabilities, maintaining security while preserving necessary network functionality.

Inventive Principle:

Principle #25Self-service

3Productivity

If containerized applications are deployed with broad network access, then service functionality is enhanced, but the risk of data leakage and malware spread increases

Engineering Contradiction:

Improveservice functionalityVSAvoiddata leakage and malware spread

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent segments network access by implementing granular security policies that control which specific ports and protocols each container can access. Instead of allowing broad network access, the system divides network permissions into fine-grained segments based on application requirements, enabling necessary service functionality while minimizing exposure that could lead to data leakage or malware spread.

Inventive Principle:

Principle #1Segmentation

4Measurement precision

If security scanning and monitoring are implemented for container ports, then vulnerability detection is improved, but system complexity increases

Engineering Contradiction:

Improvevulnerability detectionVSAvoidsecurity system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent implements a universal security platform that performs multiple functions through a single integrated system. The same infrastructure that deploys and manages containers also handles security scanning, port monitoring, and vulnerability detection. This multi-functional approach improves vulnerability detection capabilities while avoiding the additional complexity that would result from separate dedicated security tools.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method and system for protecting an application from unsecure network exposure. The method includes identifying an at-risk application, wherein identifying the at-risk application further comprises determining that the application is configured incorrectly; identifying at least one port through which the at-risk application is accessible when the at-risk application is determined to be configured incorrectly; and determining, based on the identified at least one port through which the at-risk application is accessible, whether an exposure vulnerability exists, wherein the exposure vulnerability is an unapproved exposure of at least one of the at least one port to external resources.
