Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manufacturer default passwords are used to control access to IoT devices, then device access control is implemented, but security effectiveness is insufficient and user safety cannot be ensured
Solution Approach 1:
The system enables IoT devices to automatically monitor their own network traffic patterns and autonomously detect intrusions by comparing current patterns against established baselines, eliminating the need for complex manual security configuration by users while maintaining high security effectiveness
Solution Approach 2:
The system continuously monitors network traffic patterns, compares them against baseline behavior, and automatically responds to deviations by blocking suspicious devices. This closed-loop feedback mechanism provides adaptive security that adjusts to changing threats without requiring user intervention
2Measurement precision
If statistical analysis of network traffic patterns is performed to detect intrusions, then intrusion detection accuracy is improved, but system complexity increases
Solution Approach 1:
The system replaces complex manual security analysis with automated statistical computing, using algorithms to continuously analyze network traffic patterns and automatically identify intrusions based on deviations from baseline behavior, thereby achieving high detection accuracy without increasing user-facing system complexity
3Reliability
If automated anomaly detection system is implemented to monitor IoT devices, then intrusion detection capability is enhanced, but computational resources and processing time increase
Solution Approach 1:
The system focuses computational resources on detecting only the most significant deviations from baseline network traffic patterns, rather than analyzing every aspect of device behavior in equal detail. This selective monitoring approach maintains high intrusion detection capability while reducing overall computational resource consumption
