Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional penetration-testing tools are used, then security testing functionality is provided, but ease of operation deteriorates due to constant tuning and configuration management requirements
Solution Approach 1:
The system performs self-configuration by automatically discovering the target system architecture, identifying vulnerabilities, and adapting test sequences without requiring manual tuning. The penetration testing framework autonomously manages its own configuration based on real-time system analysis.
Solution Approach 2:
The system dynamically adjusts testing parameters and configuration settings based on the analyzed system characteristics. Configuration parameters are automatically modified to match the specific target environment, eliminating the need for manual configuration management.
2Adaptability or versatility
If traditional penetration-testing tools are used, then basic security testing is provided, but coverage of attack surface deteriorates due to inability to provide specific path of attack
Solution Approach 1:
The attack surface is segmented into discrete attack paths and vulnerability categories. The system divides the comprehensive security testing into specific, manageable attack sequences that can be independently analyzed and executed, improving coverage without overwhelming complexity.
Solution Approach 2:
The system performs preliminary analysis of the target system architecture before executing penetration tests. By pre-identifying potential attack vectors and system weaknesses, the framework can tailor the testing sequence to cover the most relevant attack paths specific to each target.
3Reliability
If comprehensive penetration testing is implemented, then security coverage is improved, but resource requirements worsen for small companies with limited IT resources
Solution Approach 1:
The system implements risk-based testing that focuses on the most critical attack paths and vulnerabilities relevant to the specific target system. Rather than exhaustively testing every possible vulnerability, the framework performs partial testing concentrated on high-risk areas, achieving reliable security assessment with reduced resource consumption.
4Productivity
If manual security expert involvement is used, then accurate security assessment is provided, but productivity deteriorates due to inability to scale
Solution Approach 1:
The system replaces manual expert analysis with automated artificial intelligence algorithms that perform security assessment. The AI framework substitutes human experts' mechanical analysis process with computational algorithms that can scale indefinitely without additional resource requirements.
Solution Approach 2:
The system creates virtual models and digital twins of the target system architecture to perform penetration testing. By copying the system structure into a virtual environment, the framework enables scalable automated testing without requiring physical access or expert intervention for each test scenario.

AI summary
In one aspect, a distributed security-testing infrastructure is used for attack-tree modeling for penetration testing. An API framework, fully distributed and scalable, is used to access the attack-tree modeling based on attack trees, or decision trees, to emulate attacker behavior and decisions taken during an attack. The API framework allows developers to implement the security tools into existing software to perform actions based on desired conditions as defined by the nodes of the attack tree. For example, APIs can be used along with if/else-type statements to create advanced threat models that react based on given conditions to test multiple paths through the attack tree. Nodes of the attack tree are configured to perform actions based on the output of previous attacks in other nodes. This flexible design allows for the easy modification of the threat modeling system to test new scenarios.
