Method for detecting abnormal behaviors of operators of broadcast control system

The invention discloses a method for detecting abnormal behaviors of operators of a broadcast control system, comprising a detection system which comprises a data processing module, a TF-IDF numerical calculation module, a numerical comparison module and an alarm module, the input end of the data processing module receives operation data of operators in a time period or operation data of operators in one day, the output end of the data processing module is connected with the numerical value comparison module through the TF-IDF numerical value calculation module, and the numerical value comparison module is connected with the alarm module. According to the invention, the problem that a network security product cannot give an alarm after a hacker obtains the account authority of an operator and carries out malicious operation is solved. According to the method, the similarity between the behavior of the operator in a certain time period and the behavior of the operator in other time periods can be effectively a
