Management of sensitive data on NoSQL databases

Abstract: Nowadays, NoSQL databases are winning popularity through all the e-commerce related sites and it is becoming a tendency to migrate from a relational model to others without schema. NoSQL databases are more flexible since they allow an easier adaptation of the database structure and the capability of refactoring the schema on the fly for any project without having to stop the database service and evolving the database schema. Finally, the query optimization is designed to manage large amounts of data, whereas on relational databases it is more focused on operations rather than on data. In this paper, we intend to make a demonstration on how security can be implemented on the database layer focusing on the permissions of users, this could be applied to databases where some fields can contain sensitive data that certain users should not have access to. We also test the capability of trimming determined fields of a database to have a more secure environment. For this implementation, we have chosen MongoDB for its schema less property and the lack of internal mechanisms to automatically apply Access Control Rules. In this paper, the user restrictions are implemented using a Role-Based Access Control model on MongoDB. This means that a user can be granted one or more roles previously defined, where each role would have authorizations defined to make operations in specific databases, collections or documents.
