Abstract : Recently, the evolution of technology has given rise to the Big Data phenomenon. Thus, the NoSQL Big Data management system emerged and demonstrated its efficacy in managing such data. Graph databases, favored for their capability to handle complex relationships in connected data, are a type of NoSQL database. Nevertheless, securing its data against unauthorized access is a challenging problem. Therefore, this thesis investigates recent solutions for securing graph databases. We propose two security approaches that rely on views while supporting query rewriting and the utilization of contextual information. The first approach is the Materialized Views-Based Access Control (MVAC) which relies on materializing the views and then applying Access Control Policies whenever needed. The second approach is the Extended Materialized Views-Based Access Control (EMVAC) which enforces Access Control Policies on the views prior to materializing them. Experimental results demonstrate that the former conserves storage space at the cost of responsiveness, whereas the latter enhances responsiveness at the cost of storage space.
