A Review of Critical Security Challenges in SQL-based and NoSQL Systems from 2010 to 2019

Abstract

Database security has become a very critical issue for organizations and agencies that deploy databases as major data stores for their operations. The ever-increasing data volumes to be stored, maintained and manipulated, the changing user and operational requirements, and the advancement in cloud platforms and hardware have contributed to the consistent change in trends around database research and development which are in many cases directed towards the engineering of innovative data models, techniques and systems that could help overcome the security challenges already established in the existing database management systems. This paper is an articulation of the critical security threats, challenges and vulnerabilities of two widely used database management systems (DBMS): the NoSQL and SQL-based DBMS respectively. The period under review is from 2010-2019, is perceived as a decade that recorded outstanding changes in data and database engineering respectively.
