A cascading threat detection method for internet of things automation rules

This invention relates to the field of Internet of Things (IoT) technology and is a cascading threat detection method for automated rules in IoT. It utilizes a large language model to parse rule text, extract semantic elements, and construct a semantic representation model. A semantic alignment model is built to measure the functional similarity of different rules in a rule set. A TAP rule heterogeneous graph is constructed, establishing explicit and implicit relationships respectively. A dual-attention context encoder is constructed to obtain rule embedding representations containing semantic dependency information. A global relation attention mechanism is introduced to measure the importance of explicit and implicit relation spaces under different node types. The invention determines whether cascading threat paths exist in the rule set and generates threat detection results. This invention can automatically parse rule semantics, construct explicit and implicit dual-relation graph models, and utilize multi-layer graph neural networks to achieve multi-hop inference, thereby comprehensively detecting potential rule-cascading threats.
