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.en330 - Wirtschaft04B - Beitrag Konferenzschrift80-91
