Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized security system is implemented to manage security operations and validate device identities, then network security and reliability are improved, but device complexity and system overhead increase
Solution Approach 1:
The security system is segmented into a centralized security server that handles complex security operations (certificate validation, anomaly detection, patch distribution) and lightweight security agents deployed on individual network devices. This segmentation allows the complex security functionality to be centralized while keeping individual device complexity low.
Solution Approach 2:
A centralized security server acts as an intermediary between network devices and the computing system, mediating security operations such as certificate validation, anomaly detection, and patch distribution. This intermediary handles the complexity of security management centrally, reducing the burden on individual devices while maintaining high security standards.
2Reliability
If security operations are centralized to prevent anomalous behavior and validate identities, then security reliability is improved, but processing time and operational delays increase
Solution Approach 1:
Security credentials such as certificates and security policies are pre-configured and distributed to network devices before they need to perform operations. The centralized security server validates these credentials in advance and maintains updated security databases, so that during actual operations, validation can be performed quickly using pre-prepared security information.
Solution Approach 2:
The patent replaces traditional manual security validation mechanisms with automated electronic verification systems. The centralized security server automatically validates device identities, detects anomalies, and distributes patches through electronic communication, eliminating the need for manual security checks and significantly reducing validation time while maintaining reliability.
3Reliability
If automated patch installation is implemented to secure network devices, then security maintenance is improved, but device autonomy and manual control are reduced
Solution Approach 1:
The centralized security server automatically performs security maintenance tasks including detecting vulnerable devices, downloading appropriate security patches, and installing them on network devices without requiring manual intervention. The security agents on individual devices cooperate with this automated process by receiving and applying patches, enabling self-service security maintenance that improves reliability while minimizing the need for manual operational control.
