The Internet of Things (IoT) is one of the most discussed and tackled topics in the field of computer science research. Some of the researchers are also looking to the future of the world with this technology. Due to significant research and development that has taken place on the Internet of Things, various vulnerabilities have been observed that IoT should be kept as a technology subject. As a result, many attacks against the IoT were invented before its commercial implementation. In this thesis project, we seek to study in-depth the existing security techniques. Indeed, traditional security mechanisms such as firewalls, intrusion detection, and prevention systems are deployed at the Internet level are used to protect the network from external attacks. Such mechanisms must be adapted to secure the Internet of the new generation. Many security techniques have been proposed in the literature, where an in-depth analysis must be initiated to adapt some of them in the context of the IoT. As soon as the objects can include simple sensors, medical devices, cars, planes, and even nuclear reactors and other objects which can pose risks to human life, the solutions proposed must respond in particular to the restrictions and constraints posed by this type of network.

In recent years, Cloud Computing and Big Data have been considered as the most attractive areas that are revolutionizing the IT world. Cloud Computing paradigm has recently appeared that allows running proprietary or difficult portable a pplications outside their original software environment on one or more virtual hardware platforms. Therefore, we are to developing such techniques which makes it possible to secure communication between the communicating Cloud entities. These techniques mu st take into account several factors due to the data transmitted in this type of environment is proprietary and of significant size. Conventional data security techniques are not suitable for today's cloud usage. Hence, the main research of this thesis is to define an adaptable architecture with the aim to propose a scalable system that supports cloud services. The main objective of this thesis is to define feasible security solutions dedicated to the Cloud computing context in order to robustly protect dat a stored in the Cloud. We are more precisely looking for working on NoSQL databases.
