A Security Audit Module for HBase

Abstract

NoSQL databases provide us with highly available and highly scalable data storage solutions. During the operation on huge amounts of data, security issues have become more and more important. Security audit is an important feature for NoSQL database security. An audit module will monitor and record users’ accessing activity on the database. Thus we can identify risks such as illegal operations, right violation, etc. We designed a security audit module to enhance security for HBase. We get accessing information by defining hook function in coprocessor. Then we implement a flexible set of rules to filter logs. The evaluation shows that the system can record required accessing information thus improves security of HBase.
