    Methods to secure services in an untrusted environment
    (Software Engineering 2011 – Fachtagung des GI-Fachbereichs Softwaretechnik, 2011) Huber, Matthias; Müller-Quade, Jörn
    Software services offer many opportunities like reduced cost for IT infrastructure. They also introduce new risks, for example the clients lose control over their data. While data can be secured against external threats using standard techniques, the service providers themselves have to be trusted to ensure privacy. In this paper, we examine methods that can increase the level of privacy a service offers without the need to fully trust the service provider.

    Towards a run-time model for data protection in the cloud
    (Modellierung 2018, 2018) Mann, Zoltan; Metzger, Andreas; Schoenen, Stefan
    The protection of sensitive data in the cloud is a challenge of increasing importance. It is made particularly difficult by the complex and dynamic interactions of many entities (hardware and software, as well as organizations and individuals). A model-based approach can be used to reason about these interactions and their impact on data protection during deployment and at run time. The basis for such an approach is a model of all relevant socio-technical cloud entities, which is created during deployment and kept alive at run-time to support adaptations. In this paper, we focus on the meta-model of this model. The meta-model is created during design and instantiated during deployment. We discuss what entities must be present in the meta-model to allow reasoning about data protection. In particular, we discuss to what extent the results of previous cloud modeling efforts can be reused and what extensions are necessary because of the particular requirements of data protection.

    Using Open Source Based Distributed Agents to Perform Digital Investigation in Virtual Environments
    (INFORMATIK 2017, 2017) Spiekermann, Daniel; Keller, Jörg; Eggendorfer, Tobias
    To solve the challenges of digital investigation in virtual environments, we propose the use of distributed agents to ensure valid and continuous network traffic observations in these environments. As one of the most relevant new evolution in information technology, cloud computing demands a flexible and highly dynamic infrastructure, provided by the virtualization of systems, networks and storage. However investigating computer related crime in these environments a necessity. Current techniques like computer or network forensic investigation are not suitable for these environments. The migration of virtual machines changes the environment permanently, thus every running investigation is aggravated. Our approach of open source based, distributed agents is able to implement viable investigations in these virtual environment.
