Sandbox security model for Hadoop file system

Abstract

Extensive usage of Internet based applications in day to day life has led to generation of huge amounts of data every minute. Apart from humans, data is generated by machines like sensors, satellite, CCTV etc. This huge collection of heterogeneous data is often referred as Big Data which can be processed to draw useful insights. Apache Hadoop has emerged has widely used open source software framework for Big Data Processing and it is a cluster of cooperative computers enabling distributed parallel processing. Hadoop Distributed File System is used to store data blocks replicated and spanned across different nodes. HDFS uses an AES based cryptographic techniques at block level which is transparent and end to end in nature. However cryptography provides security from unauthorized access to the data blocks, but a legitimate user can still harm the data. One such example was execution of malicious map reduce jar files by legitimate user which can harm the data in the HDFS. We developed a mechanism where every map reduce jar will be tested by our sandbox security to ensure the jar is not malicious and suspicious jar files are not allowed to process the data in the HDFS. This feature is not present in the existing Apache Hadoop framework and our work is made available in github for consideration and inclusion in the future versions of Apache Hadoop.

Studying the Security and Privacy Issues of Big Data in the Saudi Medical Sector

“…The purpose of the paper is to provide an overview of the security and privacy challenges associated with big data. Gousiya et al in [19] proposed a sandbox security model for the Hadoop file system. The purpose of the paper is to provide a security mechanism for the Hadoop file system, which enables secure execution of untrusted code.…”
