Network security system for achieving effective management through cloud data analysis

The invention relates to the technical field of network security, in particular to a network security system capable of achieving effective management through cloud data analysis. The system comprises a data information receiving unit. According to the invention, a data content analysis unit analyzes different data contents, obtains data content types, generates data content type information, and transmits the data content type information to an abnormal address qualified data rate analysis unit, and the input end of the abnormal address qualified data rate analysis unit is connected with the output end of an abnormal address data extraction unit. According to the method and the device, the abnormal address is acquired, and the normal data rate released by the abnormal address is judged by combining the data content type information transmitted by the data content analysis unit, so that whether the abnormal address can be recovered to the normal address or not can be determined again, a network security syste
