The present application relates to a kind of jurisdiction enterprise
network security management and control method,
system and computer readable storage medium, the multi-source
heterogeneous network security data of each enterprise in jurisdiction is collected, and the enterprise correlation graph is constructed;Using graph neural network constructs and learns enterprise correlation graph, obtains the
graph embedding vector of each enterprise;In the attention calculation of graph neural network, the real-time risk
score of neighbor enterprise is as input;Using large
language model, the semantic analysis of unstructured text data is carried out, the implicit correlation between enterprises and
potential risk semantics are mined, and the enterprise correlation graph is updated based on implicit correlation and
potential risk semantics;Based on the updated enterprise correlation graph,
graph embedding vector and real-time security data, the dynamic risk
score of each enterprise is calculated using fusion risk
score model;Based on dynamic risk score, risk trend is predicted, and using explainable technology, early warning information containing risk cause explanation is generated.The present application significantly improves the
network security protection capability of jurisdiction.
