Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional vulnerability scanning and prioritization methods are used, then all vulnerabilities can be identified, but the system cannot effectively prioritize which vulnerabilities to remediate first, leading to resource waste and potential security gaps

Engineering Contradiction:

Improvevulnerability remediation efficiencyVSAvoidcontextual information about attack paths

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The system segments the vulnerability assessment process into distinct components: vulnerability detection, attack path analysis, node importance evaluation, and prioritization scoring. Each component handles specific aspects independently, allowing the system to process large numbers of vulnerabilities efficiently while maintaining contextual information about their interrelationships in potential attack paths.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system introduces an intermediary attack path modeling component that connects vulnerability data with prioritization decisions. This intermediary analyzes how vulnerabilities relate to potential attacker pathways and node importance, providing contextual information that bridges the gap between raw vulnerability data and remediation prioritization without requiring direct analysis of all vulnerability combinations.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If comprehensive attack path analysis is performed on all network nodes, then accurate prioritization can be achieved, but the computational complexity and time required increase significantly

Engineering Contradiction:

Improvevulnerability prioritization accuracyVSAvoidsystem computational complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system applies local quality by focusing computational resources on analyzing specific portions of the network that are most relevant to attack paths. Instead of uniformly analyzing all network nodes, it identifies and prioritizes analysis of nodes that lie on potential attack paths or have higher importance scores, thereby maintaining accuracy while reducing overall computational complexity.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system performs preliminary actions by pre-calculating node importance metrics and potential attack path structures before conducting full vulnerability prioritization. This preliminary analysis creates a framework that guides subsequent detailed analysis, reducing the computational burden of comprehensive attack path analysis while maintaining prioritization accuracy.

Inventive Principle:

Principle #10Preliminary action

3Manufacturing precision

If manual assessment of each vulnerability is performed, then detailed analysis can be conducted, but the time and resources required become prohibitive for large networks

Engineering Contradiction:

Improvevulnerability assessment detailVSAvoidassessment time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The system implements self-service by automatically performing vulnerability assessment, attack path analysis, and prioritization without requiring manual intervention for each vulnerability. The automated system evaluates vulnerabilities, analyzes their context within potential attack paths, and generates prioritization recommendations, maintaining detailed assessment quality while dramatically reducing the time and resources required compared to manual processes.

Inventive Principle:

Principle #25Self-service

AI summary

The node exposure score generator and the attack path modeling component are configured to cooperate to analyze the actual detected vulnerabilities that exist for that network node in the network, the importance of network nodes in the network compared to other network nodes in the network, and the key pathways within the network and the vulnerable network nodes in the network that a cyber-attack would use during the cyber-attack in order to provide an intelligent prioritization of remediation actions to remediate the actual detected vulnerabilities for each network node from the network protected by a cyber security appliance.
