	We describe the data analysis structure that is integrated into the Karabo framework [1] to support scientific experiments and data analysis at European XFEL GmbH. The photon science experiments have a range of data analysis requirements, including online (i.e. near real-time during the actual measurement) and offline data analysis. The Karabo data analysis framework supports execution of automatic data analysis for routine tasks, supports complex experiment protocols including data analysis feedback integration to instrument control, and supports integration of external applications. The online data analysis is carried out using distributed and accelerator hardware (such as GPUs) where required to balance load and achieve near real-time data analysis throughput. Analysis routines provided by Karabo are implemented in C++ and Python, and make use of established scientific libraries. The XFEL control and analysis software team collaborates with users to integrate experiment specific analysis codes, protocols and requirements into this framework, and to make it available for the experiments and subsequent offline data analysis.

Cyber security aspects are often not thoroughly addressed in the design of light source SCADA system. In general the focus remains on building a reliable and fully-functional ecosystem. The underlying assumption is that a SCADA infrastructure is a closed ecosystem of sufficiently complex technologies to provide some security through trust and obscurity. However, considering the number of internal users, engineers, visiting scientists, students going in and out light source facilities cyber security threats can no longer be minored. At the European XFEL, we envision a comprehensive security layer for the entire SCADA infrastructure. There, Karabo [1], the control, data acquisition and analysis software shall implement these security paradigms known in IT but not applicable off-the-shelf to the FEL context. The challenges are considerable: (i) securing access to photon science hardware that has not been designed with security in mind; (ii) granting limited fine-grained permissions to external users; (iii) truly securing Control and Data acquisition APIs while preserving performance.
