Publikation Blockchain as an enabler for cybersecurity use case: electronic health records in Switzerland(Sun SITE, Informatik V, RWTH Aachen, 2020) Moriggl, Pascal; Asprion, Petra; Kramer, Fabienne; Asprion, Petra; Bāliņa, Signe; Forbrig, Peter; Kampars, Jānis; Kirikova, Mārīte; Møller, Charles; Morichetta, Andrea; Roelens, Ben; Sandkuhl, KurtIn the application of Electronic Health Records (EHR), cybersecurity is an essential control and needs to be strongly considered to fulfill data protection requirements. Regarding cybersecurity needs in Healthcare, blockchain-based technologies seem promising due to the inherent security features. Therefore, this study investigates in cybersecurity requirements for EHR and whether a blockchain-based solution can cover these. There are already approaches which apply Blockchain for EHR, but these do not explicitly consider cybersecurity, which forms the research gap. As a unit of analysis, 'Hyperledger Sawtooth' as an enterprise blockchain platform was used. The results showed that Hyperledger Sawtooth performs quite well regarding the coverage of cybersecurity-relevant requirements for EHR. However, there are 'natural' divergences concerning specific cybersecurity attributes between blockchain-based and non-blockchainbased systems. The outcome of this study is a generic assessment tool which can be used to assess the coverage of cybersecurity requirements for both blockchainbased and non-blockchain-based EHR systems.04B - Beitrag KonferenzschriftPublikation Blockchain as Enabler for Cybersecurity in the Context of Electronic Health Records(Hochschule für Wirtschaft FHNW, 2019) Kramer, Fabienne; Asprion, PetraAfter the introduction of Bitcoin, the interest in Blockchain increased tremendously. In addition to Blockchain’s first application in cryptocurrencies, other applications and promising ideas for applications have emerged. Blockchain is also suitable for cybersecurity applications. With the connection of cybersecurity to healthcare, Blockchain has great potential due to the sensitive data being processed in this sector. In the area of electronic health records, cybersecurity is an important aspect because of the need to comply with regulations, especially on data protection. Cyber-attacks are becoming more frequent and more complex. These attacks are often successful and have major financial consequences. Due to the sensitivity of the data, cybersecurity is especially important in the healthcare sector. Cyberattacks are particularly serious in healthcare and therefore a major problem. Moreover, there is a potential that Blockchain can bring improvements in cybersecurity. For these reasons, this study was carried out. This study investigates the coverage of cybersecurity relevant requirements to electronic health record systems by Blockchain. Additionally, a system not based on Blockchain is considered for comparison....11 - Studentische Arbeit
