In cloud computing environment access policies will define certain restrictions on the behavior of cloud users which are part of the cloud ecosystem. With rapid development in recent technologies like cloud computing, Internet of things, grid computing many cooperating processes which are belonging to different enterprises need to exchange their data as well as services. So in this regard, security and privacy are the major concerns in developing such communications. We need to develop appropriate secured access policies to keep user data safe which is there on the cloud server. This paper implements access control model based on cloud user attributes and roles. SS-ABAC (Secured Scalable Attribute Based Access Control) is proposed where to access or to perform operations on the object is based on roles and attributes of the subject entity as well as environmental condition and simulation of experimental result shows that our model will reduce unauthorized access to cloud data and also minimizes access to services hosted by the cloud service provider. .
