Konferensbidrag (refereegranskat)abstract
- Trends show that cyber attacks targeting critical infrastructures are increasing, but security research for protecting such systems are challenging. There is a gap between the somewhat simplified models researchers at universities can sustain contra the complex systems at infrastructure owners that seldom can be used for direct research. There is also a lack of common datasets for research benchmarking. This paper presents a national experimental testbed for security research within supervisory control and data acquisition systems (SCADA), accessible for both research training and experiments. The virtualized testbed has been designed and implemented with both vendor experts and security researchers to balance the goals of realism with specific research needs. It includes a real SCADA product for energy management, a number of network zones, substation nodes, and a simulated power system. This environment enables creation of scenarios similar to real world utility scenarios, attack generation, development of defence mechanisms, and perhaps just as important: generating open datasets for comparative research evaluation.

- Bioactivity of cod (Gadus morhua) and chicken (Gallus domesticus) protein hydrolysates before and aft er in vitro gastrointestinal (GI) digestion was investigated using yeast Saccharomyces cerevisiae as a model organism. Both hydrolysates were exposed to in vitro GI digestion prior to cellular exposure to simulate digestion conditions in the human body and therefore investigate the role of modulations in the GI tract on the cell response. The effect of digested and undigested hydrolysates on intracellular oxidation, cellular metabolic energy and proteome level was investigated. No diff erence in the eff ect on intracellular oxidation activity was obtained between cod and chicken hydrolysates, while higher aff ect on intracellular oxidation was provided by digested hydrolysates, with relative values of intracellular oxidation of cod of (70.2 +/- 0.8) and chicken of (74.5 +/- 1.4) % than by undigested ones, where values of cod and chicken were (95.5 +/- 1.2) and (90.5 +/- 0.7) %, respectively. Neither species nor digestion had any eff ect on cellular metabolic energy. At proteome level, digested hydrolysates gave again signifi cantly stronger responses than undigested counterparts; cod peptides here also gave somewhat stronger response than chicken peptides. The knowledge of the action of food protein hydrolysates and their digests within live cells, also at proteome level, is important for further validation of their activity in higher eukaryotes to develop new functional food ingredients, such as in this case chicken and cod muscle-derived peptides.
