Abstract
Detecting abnormal user behavior via temporally regularized tensor factorization. A method may include obtaining behavioral data of a plurality of users of cloud services to establish a first behavioral baseline; obtaining behavioral data for a particular user of the plurality of users to establish a second behavioral baseline; determining a first variation of behavior between the second and first behavioral baseline to determine an expected behavior; creating a tensor model for a succession of pre-determined time periods comprising multiple three-dimensional tensors; determining a temporal dependence between the multiple three-dimensional tensors; determining a temporal smoothness between the multiple three-dimensional tensors; predicting a future variation in behavior of the particular user based on a combination of the temporal dependence and the temporal smoothness, where the future variation in behavior indicates a potential security threat; and performing a remedial security action on a client device based on the predicted future variation in behavior.
