A probe into process-level attack detection in industrial environments from a side-channel perspective

Process-level detection of cyberattacks on industrial control systems pertain to observing the physical process to detect implausible behavior. State-of-the-art techniques identify a baseline of the normal process behavior from historical measurements and then monitor the system operation in real time to detect deviations from the baseline. Evidently, these techniques are intended to be connected to the control flow to be able to acquire and analyze the necessary measurement data, which makes them susceptible to compromise by the attacker. In this paper, we approach process-level attack detection from a side-channel perspective, where we investigate the feasibility and efficacy of monitoring industrial machines through external sensors. The sensors measure physical properties of the process that are bound to change during a cyberattack. We demonstrate the viability of our approach through simulations and experiments on real industrial machines

The well in the settlement - environmental studies through insect analysis on well samples

In this paper, I present the results from analysis of subfossil insect remains in investigated wells from four settlements dating to prehistoric and medieval time in the county Uppland, southeast Sweden. The prehistoric settlements are dating from Neolithic time until Iron Age, but the majority of the investigated wells are from the first part of Iron Age and primarily the Pre Roman Iron Age and Roman Iron Age (following the time chronology by Hedeager & Kristiansen, 1985).Arkeologi E4 Upplan

Insect fossils from Breiduvik, Tjörnes

Three samples from the excavation of a Viking age pithouse in Breidavik were subsampled and investigated for the content of fossil insect remains, primarily Coleoptera (beetles)

The Macrofossil Remains : Preliminary Report on selected samples from Hrísbrú, Iceland, 2004

During excavations at Hrísbrú 2004, samples were collected for investigation on macrofossil remains, mainly insect remains. The preliminary results are presented in this report

Geologisk rapport för Vintrosa och Sanna, Örebro län

Rapporten är en sammanställning av geologin, speciellt jordarterna, runt platserna Vintros och Sanna väster om Örebro. Inför utbyggnaden av E18 mellan Örebro och Oslo, utförde Societas Archaeologica Upsaliensis (SAU) arkeologiska slutundersökningar på platserna Vintrosa och Sanna. Båda dessa platser har en speciell jordartsgeologi och en del frågor uppstod i samband utgrävningen
