Data security policy device and system based on artificial intelligence

The invention provides a data security policy device and system based on artificial intelligence, the device comprises a data acquisition module, a data analysis module, a data monitoring module and a security policy adjustment module, the data acquisition module is used for acquiring key data such as user access records, network traffic and system logs; the data analysis module combines the collected key data with a risk knowledge base, generates a safety performance index and presets a safety performance baseline; the data monitoring module is used for monitoring safety performance indexes and safety performance baselines in real time, and generating a safety alarm if abnormity is found; and the security policy adjustment module is used for formulating or updating security parameters according to the acquired security alarm. According to the method, the unknown security threats are identified by analyzing the user access records, the abnormity of the network flow and the sensitive words of the system logs,
