||Automatic Context-Based Policy Generation from Usage- and Misusage-Diagrams
||In systems with a very dynamic process like Industry 4.0, contexts of all
participating entities often change and a lot of data exchange happens with
external organizations such as suppliers or producers which brings concern
about unauthorized data access. This creates the need for access control
systems to be able to handle such a combination of a highly dynamic system and
the arising concern about the security of data. In many situations the
decision for access control depends on the context information of the
requester. Another problem of dynamic system is that the manual development
of access policies can be time consuming and expensive. Approaches using
automated policy generation have shown to reduce this effort.
In this master thesis we introduce a concept which combines context based
model-driven security with automated policy generation and evaluate if it
is a suitable option for the creation of access control systems and if it
can reduce the effort in policy generation. The approach makes use of usage
and misusage diagrams which are on a high architectural abstraction level
to derive and combine access policies for data elements which are located
on a lower abstraction level.
||Traceability of Telemetry Data in Hybrid Architectures
||With the rise of Software-as-a-Service products, the software development landscape transformed to a more agile and data-driven environment. The amount of telemetry data, collected from the users actions, is rapidly increasing and with it the possibilities but also the challenges of using the collected data for quality improvement purposes.
LogMeIn Inc. is a global company offering Software-as-a-Service solutions for remote collaboration and IT management. An example product is GoToMeeting which allows to create and join virtual meeting rooms.
This Master’s Thesis presents the JoinTracer approach which enables the telemetry-data-based traceability of GoToMeeting join-flows of the GoToMeeting architecture. The approach combines new mechanics and already existing traceability techniques from different traceability communities to leverage synergies and to enable the traceability of individual join-flows.
In this work, the JoinTracer approach is designed and implemented as well as evaluated regarding the functionality, performance and acceptance. The results are discussed to analyze the future development and the applicability of this approach to other contexts as well.
