The MATE (Man-At-The-End) model, in which an attacker has access to the target software and/or hardware environment to be exploited and the ability to observe and modify that environment, poses unique challenges for both defense and offense. The CheckMATE workshop focuses on exploration of both offensive and defensives techniques under this model. CheckMATE will provide a discussion forum for researchers and industrial practitioners that are exploring theorentical, practical, and emperical studies in this interesting area of security.

The numerous γ-aminobutyric acid type A receptor (GABAAR) subtypes are differentially expressed and mediate distinct functions at neuronal level. In this study we have investigated GABAAR-mediated modulation of the spontaneous activity patterns of primary neuronal networks from murine frontal cortex by characterizing the effects induced by a wide selection of pharmacological tools at a plethora of activity parameters in microelectrode array (MEA) recordings. The basic characteristics of the primary cortical neurons used in the recordings were studied in some detail, and the expression levels of various GABAAR subunits were investigated by western blotting and RT-qPCR. In the MEA recordings, the pan-GABAAR agonist muscimol and the GABABR agonist baclofen were observed to mediate phenotypically distinct changes in cortical network activity. Selective augmentation of αβγ GABAAR signaling by diazepam and of δ-containing GABAAR (δ-GABAAR) signaling by DS1 produced pronounced changes in the majority of the activity parameters, both drugs mediating similar patterns of activity changes as muscimol. The apparent importance of δ-GABAAR signaling for network activity was largely corroborated by the effects induced by the functionally selective δ-GABAAR agonists THIP and Thio-THIP, whereas the δ-GABAAR selective potentiator DS2 only mediated modest effects on network activity, even when co-applied with low THIP concentrations. Interestingly, diazepam exhibited dramatically right-shifted concentration-response relationships at many of the activity parameters when co-applied with a trace concentration of DS1 compared to when applied alone. In contrast, the potencies and efficacies displayed by DS1 at the networks were not substantially altered by the concomitant presence of diazepam. In conclusion, the holistic nature of the information extractable from the MEA recordings offers interesting insights into the contributions of various GABAAR subtypes/subgroups to cortical network activity and the putative functional interplay between these receptors in these neurons.

In Deutschland sichert der Staat durch gesetzlich verankerte Versicherungen seine Burger gegen existenzielle Risiken. Dazu gehoren die Krankheit (Krankenversicherung), der Einkommensverlust im Alter (Rentenversicherung), das Gesundheitsrisiko durch einen Arbeitsunfall oder eine Berufskrankheit (Unfallversicherung), die Arbeitslosigkeit (Arbeitslosenversicherung) und die Pflegebedurftigkeit (Pflegeversicherung). Die Burger brauchen sich gegen diese Risiken im Prinzip nicht freiwillig, z. B. durch Privatversicherungen, abzusichern, die indes zunehmende Bedeutung gewinnen. Die Durchfuhrung der gesetzlich abgesicherten Risiken uberlasst der Staat mehreren offentlich-rechtlichen Institutionen, deren Ausgestaltung im Wesentlichen von den Sozialpartnern (Vertreter der Arbeitgeber und Arbeitnehmer) bestimmt wird und denen der Staat gesetzliche Vorgaben macht, die er auch kontrolliert.
