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 tenant applications or application classes, preferably along with actions to be taken in the event a request to execute an application is anticipated to exceed defined workflow limits. A set of application profiles are generated. Typically, a profile comprises information, such as a request defined by one or more request variables, one or more “constraints,” one or more “request mappings,” and one or more “actions.” A constraint is a maximum permitted workload for the application. A request mapping maps a request variable to the constraint, either directly or indirectly. The profile information defines how a request is mapped to a workload to determine whether the request is in policy or, if not, what action to take.

First claim

The invention claimed is:

1. A method of minimizing application-level denial-of-service attacks with respect to compute resources in a multi-tenant shared infrastructure, the method comprising:
profiling anticipated application behavior in response to one or more requests to generate an application profile having at least one workload constraint, the application profile including a mapping of a request type to a workload and a workload limit;
upon receipt of a request, and prior…
