description: The purpose of the work is to automate the analysis of access control in heterogeneous Big Data systems. The research set the following goals: 1. To highlight the features of access control characteristic of heterogeneous Big Data processing systems. 2. Analyze the methods of access differentiation in Big Data processing systems. 3. Propose methods of automated formation of data processing graph and analysis of coordinated security policy in heterogeneous Big Data processing systems. 4. Develop and conduct experimental testing of the program prototype. In this paper the research in the field of building secure Big Data processing systems has been carried out. The key features of such systems that distinguish them from traditional RDBMS are identified. A comparative analysis of access control methods has been performed, which led to the choice of the attributive approach. Algorithms of security policy analysis and automated data life cycle graph generation are proposed. A prototype tool based on the described algorithms is developed. The results of the prototype functioning with increasing input data flow demonstrate the prospects for further development and implementation in Big Data processing systems with an improved level of protection.
