Cloud security and privacy model for providing secure cloud services

Cloud computing is becoming increasingly a magical solution and a widely adopted technology for delivering services over the Internet thanks to its diverse benefits, including services on demand, reducing costs, sharing and configuring computing resources, and high services scalability and flexibility. However, with the emergence of this technology, the concept of security and privacy has become a major barrier to cloud services adoption. Indeed, many research works have been done to identify cloud security and privacy issues. It is in this context that in this paper, we will provide a new cloud security and privacy model (CSPM) into layers which can be taken into account by cloud providers during all the stages of cloud services building and monitoring. This model will permit to overcome this cloud services barrier adoption and thus, to build confidence in cloud services and also to provide secure services. Finally, we will present some security threats and attacks, and propose, according to CSPM, some countermeasures.
