Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent creates a simulated environment that copies real-world network conditions, devices, and vulnerabilities. This simulation allows automated agents to practice and learn penetration testing techniques without requiring human experts for every test, thereby reducing time consumption while maintaining detection accuracy through realistic scenario replication.

Inventive Principle:

Solution Approach 1:

The patent develops a multi-functional automated agent system that can perform various penetration testing tasks across different network environments and vulnerability types. This universal agent replaces the need for multiple specialized human experts, reducing resource requirements while maintaining comprehensive security knowledge through integrated learning capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The simulated environment copies complex real-world security scenarios, allowing automated agents to acquire security knowledge through repeated practice and learning. This eliminates the need for expensive human expert resources while preserving comprehensive security insights through realistic scenario replication and automated knowledge accumulation.

Solution Approach 1:

The patent implements preliminary training of automated agents in simulated environments before deploying them to real systems. This preliminary action allows agents to develop accurate vulnerability detection capabilities through extensive practice, enabling rapid real-world testing without sacrificing accuracy since the agents have already learned thorough detection patterns in advance.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent enables continuous automated penetration testing through reinforcement learning agents that can operate without interruption. The agents continuously learn from each test result and improve their detection accuracy over time, maintaining high precision even at rapid speeds through uninterrupted learning and adaptation cycles.

Inventive Principle:
Principle #20Continuity of useful action

4Object-affected harmful factors

If simulated environments are used for training, then testing cost and risk are reduced, but realism and applicability to production networks may worsen

Engineering Contradiction:
Improvetesting riskVSAvoidapplicability to production networks
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent uses simulated environments for preliminary training of automated agents before deployment to production networks. This staged approach allows agents to learn basic penetration testing skills safely in simulation, then gradually transition to more realistic environments, ensuring both low training risk and high production applicability through progressive adaptation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements dynamic training environments that can adjust their realism level based on agent development stage. Early training uses simplified simulations for safety, while later stages introduce progressively more complex and realistic scenarios, optimizing both risk reduction and production network applicability through adaptive environment complexity.

Inventive Principle:

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.
