Abstract
A method of detecting anomalous user behavior in a cloud environment includes receiving a vector that comprises counts of actions taken by the user during a current time interval; determining whether an action count in the vector is greater than a global mean; building a scale table by combining new action skills that are above a threshold and original action skills if below the threshold; and identifying outliers when the action count is greater than the global mean multiplied by a corresponding action scale from the scale table.
