Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hardware-based security systems are used for threat detection and mitigation, then device reliability is improved, but processing capability for computationally complex threats deteriorates
Solution Approach 1:
The system divides the network into multiple zones with different security requirements and processes packets differently based on their destination zone. Fast-path processing handles routine packets quickly, while deep-path processing performs comprehensive analysis only when needed, segmenting the processing workload to improve overall productivity without sacrificing reliability.
Solution Approach 2:
The system dynamically adjusts processing depth and methodology based on real-time conditions, including packet characteristics, network state, and threat intelligence. The controller can reprogram network nodes to change processing behavior on-the-fly, allowing the system to adapt its productivity to match the complexity of threats encountered while maintaining reliable security coverage.
2Productivity
If more computing resources are allocated to threat detection, then processing capability is improved, but scalability to high data rates deteriorates
Solution Approach 1:
The system segments processing into fast-path and deep-path modes, allowing most packets to traverse with minimal processing while only suspicious or zone-specific packets receive intensive analysis. This segmentation enables the system to scale to high data rates without requiring proportional increases in computing resources for all packets.
Solution Approach 2:
The controller provides centralized intelligence that can reprogram multiple network nodes to perform different security functions based on current threats and traffic patterns. This multi-functionality allows the same hardware infrastructure to adapt to varying processing demands, improving scalability while maintaining high processing capability where needed.
3Measurement precision
If comprehensive packet analysis is performed for all packets, then measurement precision for threat detection is improved, but processing speed deteriorates
Solution Approach 1:
The system dynamically selects between fast-path and deep-path processing based on packet characteristics, destination zone, and current threat intelligence. This dynamic approach ensures comprehensive analysis (high precision) is applied only when necessary, while routine packets receive expedited processing, maintaining both precision and speed.
Solution Approach 2:
Different processing depths are applied to different packets based on their specific characteristics and destination zones. Critical zones receiving enhanced scrutiny while less sensitive zones use standard processing, optimizing the balance between detection precision and processing speed for each local context.
4Adaptability or versatility
If dynamic reprogramming of network nodes is implemented, then adaptability to new threats is improved, but device complexity deteriorates
Solution Approach 1:
The controller acts as an intermediary that centralizes the complexity of dynamic reprogramming. Individual network nodes receive simplified reprogramming instructions from the controller rather than implementing complex adaptive logic themselves. This distributes complexity to the controller, which has full visibility and coordination capabilities, reducing the burden on individual nodes while maintaining system-wide adaptability.
