Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If machine learning-based detection engines are used, then detection accuracy is improved, but the ability to tune the solution rapidly deteriorates due to substantial time and effort required for retraining and deploying ML models
Solution Approach 1:
The system segments the detection engine into multiple independent components: pattern-matching algorithms for rule-based detection, ML-based detection for anomaly detection, and a configuration system that manages detection parameters. This segmentation allows the pattern-matching and configuration components to be tuned rapidly without retraining the ML models, thus maintaining detection accuracy while improving adaptability.
Solution Approach 2:
The system implements dynamic configuration capabilities that allow security operators to adjust detection parameters, thresholds, and rules in real-time without retraining ML models. The configuration system enables dynamic modification of detection sensitivity, event correlation rules, and response thresholds, allowing rapid adaptation to emerging threats while preserving the trained ML model performance.
2Ease of operation
If manual configuration is used for detection rules, then granular detection control is achieved, but the difficulty to maintain, test, and update detection logic increases
Solution Approach 1:
The system incorporates automated testing and validation feedback mechanisms that verify detection rule configurations before deployment. The configuration system provides feedback on potential conflicts, performance impact, and validation results, allowing operators to maintain granular control while reducing the complexity of maintenance and updates through automated verification.
Solution Approach 2:
The system enables self-service configuration capabilities where security operators can independently configure, test, and deploy detection rules without requiring extensive manual intervention or complex coordination. The automated testing framework and configuration management system allow operators to self-validate their configurations and rapidly update detection logic.
3Productivity
If pattern-matching algorithms are used to evaluate events, then detection rules can be applied systematically, but performance deteriorates due to high volume and variety of events requiring external calls for additional data
Solution Approach 1:
The system performs preliminary event filtering, scoring, and enrichment before pattern-matching evaluation. Events are pre-processed to extract relevant features, assign risk scores, and enrich with contextual data in advance of the pattern-matching stage, reducing the need for external calls during systematic rule evaluation and improving overall performance.
Solution Approach 2:
The system introduces an event scoring and filtering intermediary layer between raw event generation and pattern-matching evaluation. This intermediary processes events to identify high-priority candidates, filter low-risk events, and prepare optimized event representations, reducing the computational burden on pattern-matching algorithms and minimizing external data calls.
4Extent of automation
If ML models are used for detection, then automated detection is achieved, but the ability to understand why an alert is registered deteriorates due to the opaque nature of ML models requiring full-cycle investigation
Solution Approach 1:
The system merges ML-based automated detection with rule-based detection and event correlation capabilities. By combining multiple detection approaches, the system maintains automated detection while providing interpretable results through rule explanations, event correlation context, and configurable detection logic that security operators can understand and investigate.
Solution Approach 2:
The system introduces an intermediary explanation layer that translates ML model decisions into interpretable formats. This intermediary provides detection rationale, highlights relevant events and patterns, and offers configurable explanation levels that help security operators understand alert reasons without requiring full-cycle investigations, bridging the gap between automated detection and human interpretability.
