Abstract
Denial-of-service attacks are prevented or mitigated in a cloud compute environment, such as a multi-tenant, collaborative SaaS system. This is achieved by providing a mechanism by which characterization of 'legitimate' behavior is defined for accessor classes, preferably along with actions to be taken in the event an accessor exceeds those limits. A set of accessor 'usage profiles' are generated. Typically, a profile comprises information, such as a “request time window,” one or more “constraints,” and one or more “actions.” A request time window defines a time period over which request usage is accumulated and over which constraints are applied. A constraint may be of various types (e.g., number of transactions, defined resource usage limits, etc.) to be applied for the usage monitoring An action defines how the system will respond if a particular constraint is triggered. By applying the constraints to accessor requests, over-utilization of compute resources is enabled.
