IDSaaS: Intrusion Detection System as a Service in Public Clouds

In a public cloud computing environment, consumers cannot always just depend on the cloud provider's security infrastructure. They may need to monitor and protect their virtual existence by implementing their own intrusion detection capabilities along with other security technologies within the cloud fabric. Intrusion Detection as a Service (IDSaaS) targets security of the infrastructure level of a public cloud (IaaS) by providing intrusion detection technology that is highly elastic, portable and fully controlled by the cloud consumer. A prototype of IDSaaS is described.
