The commercial success of Cloud Computing and recent developments in Grid Computing have brought platform virtualization technology into the field of high performance computing. Virtualization offers both more flexibility and security through custom user images and user isolation. In this paper, we present an approach for combined malware detection and kernel root kit prevention in virtualized Cloud...
The use of user specific virtual machines (VMs) in Grid and Cloud computing reduces the administration overhead associated with manually installing required software for every user on every computational resource. However, a large number of user specific VMs increases the risk of security attacks. In particular, Cloud computing providers like Amazon suffer from these problems, since they offer different...
Cloud computing uses virtualization technologies to offer a non-shared use rental of computer resources with publicly accessible worker nodes. However, unlike grid computing, cloud computing as implemented by Amazon, IBM, Google and Microsoft only offers compute and storage resources from a single organization. Many of the cross-site and cross-organizational advantages offered by grid computing are...
In this paper, a novel approach for enabling Grid users to autonomously install and use custom software on demand using an image creation station is presented, while at the same time offering new security mechanisms to protect both software and data from other Grid users and external attackers. An automated dynamic firewalling mechanism enables both virtual organization and user-based network security...
In this paper, an approach to create virtual cluster environments is presented which enables fine grained service-oriented applications to be executed side by side to traditional batch job oriented Grid applications. Secure execution environments which can be staged into an existing batch job environment are created. A grid enabled workflow engine to build complex application workflows which are executed...
