Service & Application Security

Service-oriented architectures and elastic deployment models of IT-resources serve as key-enablers of modern service infrastructures in corporations, public institutions as well as the internet. The security of the cloud-platforms, infrastructures and dedicated cloud service offerings (Software-as-a-Service) available is a crucial success factor for the providers of such cloud and service offerings.

Expertise

In the year 2009, the Fraunhofer AISEC (using its former term Fraunhofer SIT) published the first comprehensive, German-language study of security in the field of cloud computing. Key results comprised of a systematic taxonomy for the analysis of security as well as guidance for the users of cloud computing services. A detailed, subsequent analysis of the market leaders in cloud computing on behalf of the Federal Office for Information Security (BSI), which ended in spring 2011, revealed deep insights into the state-of-the-art of developments and technology of the most widespread, commercial service offerings in cloud computing. In addition to this, we conduct interoperability and practical comparative analysis of these offerings with open-source solutions in our laboratory.

Fraunhofer AISEC supports customers with the conception, the design, the realization and evaluation of security and reliability related aspects, as well as the robustness of SOA and Cloud solutions. Consultation of users of cloud computing service offerings, such as small and midmarket businesses, is carried out by Fraunhofer AISEC in the areas of business process outsourcing and applications in cloud computing environments. We conduct security research and analysis and, where appropriate, develop tailored applications that enable the secure and comfortable usage of cloud computing service offerings. This includes the use of innovative technologies, which enable Security-as-a-Service, e.g. identity management in the sense of Identity-as-a-Service.
