TRESPASS DETECTING SYSTEM IN A CLOUD COMPUTING SERVICE, CAPABLE OF DETECTING UNPERMITTED TRESPASSING

摘要

PURPOSE: A trespass detecting system in a cloud computing service is provided to detect trespassing between service providers and trespassing between internal VMs(Virtual Machine) by making the trespass detecting system suited to a cloud environment.;CONSTITUTION: If a traffic value of a VM(10) exceeds a threshold value, a beginning level detector(11) generates a beginning level warning of the VM. If the beginning level warning is the same as a black list of a local database, a trespass detection determiner(20) determines trespassing and generates a hyper warning. A trespass detection manager(30) receives the beginning level warning and the hyper warning. The beginning level warning and the hyper warning include a state value including a supercritical value and the usage of a memory, a CPU, and a storage. The beginning level detector exists in the VM and the beginning level warning is transmitted to the trespass detection manager.;COPYRIGHT KIPO 2013;[Reference numerals] (10) Virtual machine; (11) Beginning level detector; (12) Beginning level warning generator; (13) User environment setting applicator; (14) Analyzer; (20) Trespass detection determiner; (21) Warning correlator; (22) Trespass detection generator; (23) Format converter; (30) Trespass detection manager; (31) Warning collector; (32) User environment setter; (33) Warning processor; (34) Notifier; (41) Local database; (42) Global database; (AA) Cloud provider 2; (BB) Physical machine; (CC) Cloud provider 1; (DD,FF) Virtual interface; (EE,GG) Guest OS; (HH) Hypervisor(virtual machine monitor); (II) Hardware;
