Challenges and Security Issues of Distributed Databases
Neha Gupta, Rashmi Agrawal · 2017
Not only structured query language (NoSQL) has inherited the security issues of traditional relational database management systems along with its own due to the enhanced features of the NoSQL databases. NoSQL databases are always prone to security attacks due to the unstructured nature of data and the distributed computing environment. In NoSQL database environment, the nodes are distributed to enable parallel computing that increases the attack surface, which results in providing more complexity for security. NoSQL databases were designed to handle large datasets to meet the requirement of data analytics, and less emphasis was given on security during the design phase. NoSQL databases provide a very thin layer of security, and to make NoSQL databases secure, the user has to overcome the below-mentioned security threats. NoSQL databases segment data horizontally and share them across multiple servers. NoSQL databases lack confidentiality and integrity, and to safeguard integrity in these databases is a major concern.
