Proxy Server Network Security Learning System

The patent introduces a proxy server as an intermediary component between clients and the protected server. The proxy server handles security filtering, query analysis, and learning functions separately from the protected server, allowing the server to maintain its primary functions while the proxy handles security resource consumption. This mediator approach resolves the contradiction by providing security protection without burdening the protected server's resources.

The system segments security functions into separate modules: the proxy server handles query filtering and blocking, while the learner module handles analysis and rule generation. This segmentation allows security functions to be distributed across different components, reducing the resource burden on any single system and enabling independent optimization of each component.

The learner module implements self-service by automatically analyzing blocked queries, identifying attack patterns, and generating new filtering rules without human intervention. The system continuously learns from encountered threats and autonomously updates its security policies, enabling evolution and adaptation to new attack types while maintaining reliable security protection.

The system establishes a feedback loop where blocked queries are analyzed by the learner module, which then generates updated rules fed back to the proxy server for improved filtering. This continuous feedback mechanism enables the system to learn from attacks and adapt its security measures, resolving the contradiction between maintaining security and achieving adaptability.
