Recently non-relational databases known as NoSQL have become most popular forhandling a huge amount of data. Many organizations move from relational databases towardsNoSQL databases due to the growing popularity of cloud computing and big data. NoSQLdatabase is designed to handle unstructured data like documents, e-mails, and social mediaefficiently. It uses distributed and cooperating devices to store and retrieve data. As a largenumber of people storing sensitive data in NoSQL databases, security issues become criticalconcerns. NoSQL has many advantages like scalability and availability, but it suffers from somesecurity issues like weak authorization mechanisms. This paper reviews the different models ofNoSQL databases and the security issues concerning these databases. In addition, we present theexisting access control models in different NoSQL databases.
