    IT-Risikomanagement von Cloud-Dienstleistungen im Kontext des IT-Sicherheitsgesetzes
    (HMD Praxis der Wirtschaftsinformatik: Vol. 54, No. 1, 2017) Adelmeyer, Michael; Petrick, Christopher; Teuteberg, Frank
    Neben den Vorteilen von Cloud-Diensten ergeben sich durch ihren Einsatz häufig Risiken für die IT-Sicherheit von Unternehmen. Durch das am 12. Juni 2015 verabschiedete Gesetz zur Erhöhung der Sicherheit informationstechnischer Systeme sollen Betreiber Kritischer Infrastrukturen dazu verpflichtet werden, ihre IT besser vor Cyber-Attacken zu schützen. In diesem Kontext gilt es zu klären, welche Anforderungen Cloud-Betreiber als Dienstleister Kritischer Infrastrukturen umzusetzen haben oder inwiefern diese per Definition des IT-Sicherheitsgesetzes als Betreiber Kritischer Infrastrukturen angesehen werden können. Im Rahmen des IT-Risiko- und Sicherheitsmanagements bei Kritischen Infrastrukturen entstehen bei der Auslagerung von (zentralen) Prozessen und Funktionen zudem Unklarheiten, wie der Einsatz von Cloud-Dienstleistungen zu bewerten ist und welcher Handlungsbedarf auf die Cloud-Betreiber zukommt, zum Beispiel durch das geforderte Mindestsicherheitsniveau der IT-Systeme. In dem Beitrag werden ein Anforderungskatalog an Cloud-Dienstleistungen zur Umsetzung des IT-Sicherheitsgesetzes auf Grundlage von Experteninterviews entwickelt sowie Implikationen für das IT-Risikomanagement von Cloud-Dienstleistungen dargestellt. Abschließend werden Handlungsempfehlungen für Cloud-Betreiber und Betreiber Kritischer Infrastrukturen gegeben.AbstractAlongside the benefits of cloud computing IT security risks arise from the use of cloud services. The German act to increase the safety of information technology systems, which was issued on June 12, 2015, requires critical infrastructures to improve the protection of their IT against cyber-attacks. In this context, the requirements cloud operators have to implement as service providers of critical infrastructures, or whether they can be viewed as operators of critical infrastructures by definition of the IT security law, have to be clarified. Furthermore, concerning the IT risk management of critical infrastructures, questions arise when outsourcing (central) processes and functions to the cloud. Regarding this, the overall use of cloud services and the actions cloud operators have to take, for example in order to meet the required minimum level of safety of IT systems, have to be assessed. In this article, a requirements catalog for cloud services and service providers to implement the requirements of the IT security law is developed on the basis of expert interviews. Furthermore, implications for the IT risk management of cloud services and recommendations for cloud providers and critical infrastructures are presented.

    MANTRA: A Graph-based Unified Information Aggregation Foundation for Enhancing Cybersecurity Management in Critical Infrastructures
    (Open Identity Summit 2023, 2023) Fuxen, Philipp; Hackenberg, Rudolf; Heinl, Michael P.; Ross, Mirko; Roßnagel, Heiko; Schunck, Christian H.; Yahalom, Raphael
    The digitization of almost all sectors of life and the quickly growing complexity of interrelationships between actors in this digital world leads to a dramatically increasing attack surface regarding both direct and also indirect attacks over the supply chain. These supply chain attacks can have different characters, e.g., vulnerabilities and backdoors in hardware and software, illegitimate access by compromised service providers, or trust relationships to suppliers and customers exploited in the course of business email compromise. To address this challenge and create visibility along these supply chains, threat-related data needs to be rapidly exchanged and correlated over organizational borders. The publicly funded project MANTRA is meant to create a secure and resilient framework for real-time exchange of cyberattack patterns and automated, contextualized risk management. The novel graph-based approach provides benefits for automation regarding cybersecurity management, especially when it comes to prioriization of measures for risk reduction and during active defense against cyberattacks. In this paper, we outline MANTRA’s scope, objectives, envisioned scientific approach, and challenges.

    Towards Resilient Critical Infrastructures – Motivating Users to Contribute to Smart Grid Resilience
    (i-com: Vol. 20, No. 2, 2021) Egert, Rolf; Gerber, Nina; Haunschild, Jasmin; Kuehn, Philipp; Zimmermann, Verena
    Smart cities aim at improving efficiency while providing safety and security by merging conventional infrastructures with information and communication technology. One strategy for mitigating hazardous situations and improving the overall resilience of the system is to involve citizens. For instance, smart grids involve prosumers—capable of producing and consuming electricity—who can adjust their electricity profile dynamically (i. e., decrease or increase electricity consumption), or use their local production to supply electricity to the grid. This mitigates the impact of peak consumption periods on the grid and makes it easier for operators to control the grid. This involvement of prosumers is accompanied by numerous socio-technical challenges, including motivating citizens to contribute by adjusting their electricity consumption to the requirements of the energy grid. Towards this end, this work investigates motivational strategies and tools, including nudging, persuasive technologies, and incentives, that can be leveraged to increase the motivation of citizens. We discuss long-term and side effects and ethical and privacy considerations, before portraying bug bounty programs, gamification and apps as technologies and strategies to communicate the motivational strategies to citizens.
