Abstract
Service-Oriented Architecture (SOA) has introduced a phenomena of system's interaction with maximum users. With the development of high speed Internet services, the use of remote devices and software has rapidly increased. It has opened new gateways for renting out resources. The Cloud Service Chain is a process of ownership transfer of a service at different levels by different service providers. The concept of service chain poses novel challenges related to security, trust and privacy of data. In this chapter, we are introducing a mechanism of access control for Cloud service chains. We have discussed the realization of Role-Based Access Control (RBAC) to services of Federated-Cloud. When services are purchased in bundle, separate SLA is signed for each. We are also going to introduce a dynamic Role-Level Agreement (RLA) for such type of access control to services. The RLA will be an aggregated SLA for different services in a role. This will be helpful for service providers and the customers to sign a single document for a bundle rather than having separate one for every service.
