Assessing the Security of Big Data Systems

This article considers the problem of assessing the security of big data systems. The authors define the main aspects of big data systems as an object of security assessment and analyze the known assessment methods, including methodologies for assessing the security of information systems (ISs). Based on the obtained results, a new evaluation method is proposed that takes into account factors such as the state of the access control system in the heterogeneous systems under consideration and the number of privileged users. A mathematical formalization of the assessment is proposed, the main stages of its implementation are described, and a test example is presented.
