Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automated reinforcement learning is used to perform penetration testing, then productivity and speed of vulnerability detection are improved, but device complexity and difficulty of implementation increase

Engineering Contradiction:
Improvespeed of vulnerability detectionVSAvoidcomplexity of ARL system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary training environment that simulates production network conditions without using real production data. This intermediary layer allows the ARL agent to be trained and tested in a controlled setting, bridging the gap between simple testing and complex production environments while maintaining security and stability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary training actions in a simulated environment before deploying to production. The ARL agent undergoes extensive training on synthetic attack patterns and simulated network conditions beforehand, allowing it to be ready for rapid vulnerability detection when deployed to real systems without requiring complex real-time adaptation.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If human experts conduct penetration testing, then measurement precision and accuracy of vulnerability assessment are improved, but loss of time and productivity decrease

Engineering Contradiction:
Improveaccuracy of vulnerability assessmentVSAvoidtime required for penetration testing
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The ARL agent performs self-directed penetration testing by autonomously selecting and executing attack strategies based on learned patterns. The system serves itself by continuously learning from simulated experiences and adapting its testing approach, eliminating the need for continuous human expert intervention while maintaining high accuracy through reinforcement learning.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback loops where the ARL agent receives rewards or penalties based on the success of its penetration testing actions. This feedback mechanism allows the agent to continuously refine its vulnerability detection accuracy by learning from the outcomes of its attacks, gradually improving measurement precision through iterative optimization.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If conventional penetration testing methods are used, then ease of operation is maintained, but adaptability to evolving cybersecurity threats decreases

Engineering Contradiction:
Improvesimplicity of penetration testingVSAvoidadaptability to new threats
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The ARL system transforms static penetration testing methodologies into dynamic, adaptive processes. The agent continuously updates its attack strategies based on learned patterns from simulated threats and real-world data, allowing it to automatically adapt to evolving cybersecurity threats while maintaining operational simplicity through automated decision-making.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes key parameters of the penetration testing process by using reinforcement learning to dynamically adjust attack vectors, timing, and methods based on the target system's characteristics and observed responses. This allows the system to adapt to new threats by modifying its behavioral parameters rather than requiring complete methodological overhauls.

Inventive Principle:
Principle #35Parameter changes

4Reliability

If real-time human analysis is performed during penetration testing, then reliability of vulnerability identification is improved, but productivity and speed of testing decrease

Engineering Contradiction:
Improvereliability of vulnerability identificationVSAvoidspeed of penetration testing
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the mechanical system of human analysis with an automated ARL-based analysis system. The reinforcement learning agent automatically analyzes test results, identifies vulnerabilities, and determines their severity without human intervention, maintaining high reliability through learned patterns while dramatically increasing testing speed and productivity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The ARL system enables continuous automated analysis of penetration testing results without the interruptions inherent in human analysis. The agent continuously processes test outcomes, identifies vulnerabilities, and prepares follow-up attacks or reports without breaks, thereby maintaining reliable identification accuracy while significantly increasing the overall speed and productivity of the penetration testing process.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

Systems, apparatuses, methods, and computer program products are disclosed for determining a security vulnerability of a computer system. An example method includes initializing a policy based on initial policy data. The example method further includes selecting an action based on the policy and executing, by agent circuitry, the action in the environment. The example method further includes, subsequent to executing the action in the environment, receiving an observation of the environment and determining an updated state from the set of states based on the observation. The example method further includes determining, by the policy, a reward based on the updated state and updating the policy based on the updated state.
