Securing Cloud from Intrusion Attacks using Intrusion Detection System in Virtual Machine Environment

Abstract: 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. Traditional Intrusion Detection Systems (IDSeS) are not suitable for these environments due to their openness and limited essence. Intrusion Detection System as a Service (IDSaaS), monitors a system or a network for illegal activities in public cloud (IaaS) by providing intrusion detection technology that is portable, secure and fully controlled by the cloud service providers (CSPs). A prototype of IDS is described.
