Abstract: System and method for categorizing a plurality of network resources. Collected properties of a network resource are analyzed to determine applicability of various predefined categories to that network resource. At least one category from among the predefined categories is assigned to that network resource according to a determination of applicability of the at least one category to the network resource. A resource-specific time interval for re-categorizing each one of the network resources is dynamically adjusted based on a plurality of previous categorization results for that network resource, such that different network resources will be associated with correspondingly different re-categorization intervals.

Abstract: Disclosed are system, method and computer program product for adaptive control of actions of a user on a computer system. The system monitors one or more actions of the user, applies restriction rules to detect prohibited user actions, and blocks prohibited actions that violate at least one restriction rule. The system also collects information on allowed actions of the user and corresponding system events, analyzes in real-time the collected information about system events corresponding to the allowed actions to detect anomalous actions that did not violate any of the restriction rules, but caused abnormal increase in the usage of certain system resources. When an anomalous action is detected, the system identifies restriction rules that are associated with the detected anomalous action and edits these rules or creates new restriction rules to include the anomalous action prohibited to the user.
