The idea behind Cloud Computing is to deliver Infrastructure-, Platform-and Software-as-a-Service (IaaS, PaaS and SaaS) over the Internet on an easy pay-per-use business model. The Hochschule Furtwangen University (HFU) is running their own private cloud infrastructure, called Cloud Infrastructure and Application CloudIA. The targeted users of the CloudIA(More)
Cloud computing delivers on-demand services with ???exibility and scalability on a simple pay-per-use basis. However, major concerns regarding to security and privacy hinder a broad adoption by users, especially small- and medium-sized enterprises (SMEs). This is because existing guidelines, IT standards and laws on security and privacy do not take virtual(More)
Classic intrusion detection mechanisms are not flexible enough to cope with cloud specific characteristics such as frequent infrastructure changes. This makes them unable to address new cloud specific security issues. In this paper we introduce the cloud incident detection system Security Audit as a Service (SAaaS). It is built upon intelligent autonomous(More)
The idea behind Cloud Computing is to deliver Infrastructure-as-a-Services and Software-as-a-Service over the Internet on an easy pay-per-use business model. To harness the potentials of Cloud Computing for e-Learning and research purposes, and to small-and medium-sized enterprises, the Hochschule Furtwangen University establishes a new project, called(More)
—One characteristic of a cloud computing infrastructure are their frequently changing virtual infrastructure. New Virtual Machines (VMs) get deployed, existing VMs migrate to a different host or network segment and VMs vanish since they get deleted by their user. Classic incidence monitoring mechanisms are not flexible enough to cope with cloud specific(More)

The idea behind cloud computing is to deliver Infrastructure-, Platform- and Software-as-a-Service (IaaS, PaaS and SaaS) over the network on an easy pay-per-use business model. In this paper, we present our work, Virtual Cluster as a Service (ViteraaS), that provides on-demand high performance computing for research projects, and e-Learning and teaching(More)
Security is still a major concern in Cloud computing, especially the detection of nefarious use or abuse of cloud instances. One reason for this, is the ever-growing complexity and dynamic of the underlying system design and architecture. To be able to detect misuse of cloud instances, this work presents an anomaly detection system for Infrastructure as a(More)
Cloud computing is a type of distributed computing approach for IT Sector that leverages in efficient pooling of on-demand, self-managed virtual Infrastructures consuming them as a service by applications/organizations which would save thousands of dollars on CapEx and OpEx. To adopt this new cloud technology main concern for the consumers is the cloud(More)
