Abstract
Event information of a computing device is obtained. The event information characterizes events occurring at the computing device. Two or more of the events are grouped into an event group. The event group defines an activity. The event group is classified to classify the activity. The activity and one or more related activities are chained into a sequence. The sequence defines a behavior. Context is added to the sequence to determine a contextual behavior. A security threat is detected based on the contextual behavior.
