Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If agents collect and report data from compute assets in real-time, then anomaly detection capability is improved, but data processing complexity increases
Solution Approach 1:
The system segments data processing into multiple components: agents collecting data from compute assets, a data platform receiving and storing data, and a graph processing system analyzing relationships. This segmentation allows each component to handle specific tasks independently, reducing overall processing complexity while maintaining real-time anomaly detection capability through distributed architecture.
Solution Approach 2:
The data platform acts as an intermediary between agents and the graph processing system. It receives raw data from agents, performs initial processing and validation, stores data in a structured format, and then feeds processed data to the graph processing system. This intermediary layer simplifies the interaction between components and reduces processing complexity by pre-processing data before analysis.
2Measurement precision
If the system monitors cloud environments in real-time, then threat assessment accuracy is improved, but computational resources consumed increase
Solution Approach 1:
The system uses graph processing to analyze only the most critical relationships and patterns among compute assets, rather than processing all possible data combinations. By focusing on high-value relationships (such as data flow paths, dependency chains, and communication patterns) and using sampling techniques for graph traversal, the system achieves accurate threat assessment while reducing computational resource consumption.
Solution Approach 2:
The system dynamically adjusts monitoring parameters and graph processing depth based on detected anomalies and threat levels. When normal operation is detected, the system uses lighter processing parameters; when anomalies are detected, it increases processing intensity focused on relevant areas. This dynamic parameter adjustment maintains threat assessment accuracy while optimizing computational resource usage.
3Reliability
If polygraphs are generated for anomaly detection, then system security is improved, but data storage requirements increase
Solution Approach 1:
The system extracts only the essential information needed for security monitoring from compute assets - specifically, data about relationships, communication patterns, and operational contexts. By focusing on extracting relational data rather than all raw data, the system generates useful polygraphs for anomaly detection while minimizing data storage requirements.
Solution Approach 2:
The graph data structure serves multiple functions: storing relationships between compute assets, enabling anomaly detection, supporting threat assessment, and facilitating compliance monitoring. This multi-functionality reduces the need for separate specialized storage structures, thereby reducing overall data storage requirements while maintaining system security.
