METHOD, APPARATUS AND SYSTEM FOR PROCESSING ATTACK BEHAVIOR OF CLOUD APPLICATION IN CLOUD COMPUTING SYSTEM

The present invention discloses an apparatus for processing an attack behavior of a cloud application in a cloud computing system, including: a security analyzer, a security processor, and a policy manager, where the policy manager is configured to store a security determining rule and a malicious application processing rule; the security analyzer is configured to receive application behavior data sent by a security detector, determine, according to the application behavior data and the security determining rule, whether a cloud application running on a cloud host has an attack behavior, and when determining that the cloud application running on the cloud host has an attack behavior, send the application behavior data to the security processor; and the security processor is configured to invoke, according to the malicious application processing rule, an interface provided by a cloud controller in a cloud computing system, to process the cloud application having an attack behavior. In solutions of the present invention, security protection is performed based on an application level of cloud computing, which can prevent mutual attack between different applications on a same host, and reduce impact on a normal application.
