TY - THES A1 - Boneder, Stefan T1 - Evaluation and comparison of the security offerings of the big three cloud service providers Amazon Web Services, Microsoft Azure and Google Cloud Platform N2 - There is little to no research and literature available comparing the security offerings of different cloud providers, with security apparently being an afterthought in the decision making process when choosing a Cloud Service Provider (CPS) That is an issue this paper addresses by performing an evaluation of the security offerings of the three big Amazon Web Services (AWS), Microsoft Azure and Google Cloud Platform (GCP). Data and information are gathered and compared, about which security features are present in the Cloud Security Posture Management (CSPM) solution, as well as in classic cloud computing services. The collected data is then used to calculate a score for each CSP's performance in the categories Virtual Machine, Container and CSPM. The weights for these calculations are chosen for two use-cases. One use-case represents organizations with mature cloud security postures and focuses more on feature completeness, while the other use-case places a bigger focus on providing secure default congurations for organizations without mature cloud security posture. The results are grouped tightly together, indicating that all three evaluated CPSs have security oerings of relatively similar qualities. That said, Azure takes the top place for Virtual Machine Security and their CSPM solution, which has the advantage of oering multi-cloud support, which it's competitors don't. GCP places rst for Container security and Serverless Computing Security. Finally, for IAM solutions in the cloud, all three evaluated CSPs are tied for first place, offering simlar functionalities.
