Research for the arithmetic of cloud computing intrusion detection

The cloud computing security is very important. The intrusion detection method based on clustering has become one of the main research methods in intrusion detection at present stage. The intrusion detection system model of cloud environment is put forward. FCM clustering algorithm also has been widely used in the field of intrusion detection. However, FCM algorithm of intrusion detection in a cloud environment has some questions. For this defect of Fuzzy C-means clustering algorithm, the improved algorithm based on sample contribution is put forward.
