Problems solved by technology

First of all, various external data source systems have uneven support for access control
Secondly, although the middleware-style access control enhancement system can provide fine-grained access control, it cannot yet support all data sources
Due to the need to shield the differences of various heterogeneous data sources, the middleware system is highly complex and has a long development cycle, which requires continuous support for new data sources

Abstract

The present invention provides a Spark-oriented access control method, the steps of which include: identifying identity information of a user accessing the Spark system, finding all relevant access control rules from an access control strategy set, and converting the access control rules into security control rules; According to the safety control rules, the logical plan of the user is safely rewritten, and the logical plan is transformed into a safe logical plan that meets the access requirements; for the external data input into the Spark system, its identity and structural information are saved; Optimize the above security logic plan, generate runnable code according to the optimized security logic plan, select and control external data through identity identification and structural information, and realize access control of Spark data processing. The invention also provides a Spark-oriented access control system.

Description

technical field [0001] The present invention relates to the field of data security technology of Spark, a big data analysis tool, in particular to a Spark-oriented access control method and system, which limits the user's access authority to the data in the data set during the data analysis process, so that the user can only follow the access control method. It is required to access specific field components in data records, and finally realize fine-grained access control of data. Background technique [0002] Big data contains great value, and big data tools to mine these values ​​become the key to controlling big data. Spark (full name: Apache Spark) has become the most popular big data tool today and has received great attention from all walks of life. Although Spark technology has made great progress in terms of performance and versatility, it still faces many problems, among which data security is a major hidden danger that needs to be solved urgently. First, the enor...
