While cloud computing is gaining popularity, diverse security and privacy issues are emerging that hinder the rapid adoption of this new computing paradigm. And the development of defensive solutions is lagging behind. To ensure a secure and trustworthy cloud environment it is essential to identify the limitations of existing solutions and envision directions for future research. In this paper, we have surveyed critical security and privacy challenges in cloud computing, categorized diverse existing solutions, compared their strengths and limitations, and envisioned future research directions.

“…In the case of SaaS, the applications are usually easily reached through a thin client interface, such as a web browser. [34] stated that cloud computing types include private, public, hybrid, and community. The private cloud is devoted to a single organization in providing the different services necessary for its working.…”

Firms need cloud computing adoption for strategic and competitive goals, generating business value, and at last gaining competitive advantage. This study reviews the literature regarding cloud computing and IT governance, and presents a research model along with its hypotheses formulation to examine the factors impacting cloud computing perceived importance in several Arab firms, specifically Jordan, Saudi Arabia and United Arab Emirates by using the integration of Technology Acceptance Model (TAM) model and Technology-Organizational-Environmental (TOE) framework as adapted from [1]. 329 returned surveys from top, middle-level IT managers, and IT employees from the operational level of the studied firms were analyzed using the structural equation modeling technique. The study found relative advantage, compatibility, complexity, organizational readiness, top management commitment, and training and education as important variables for impacting cloud computing adoption using perceived ease of use and perceived usefulness as mediating variables. The model explained 61%, 63%, and 74% of cloud computing adoption for perceived usefulness, perceived ease of use and perceived importance respectively.

Cloud computing is a major trend and a fast growing phenomena in the IT world. Organizations working in different sectors such as education or business are becoming more interested in moving their applications to the cloud to boost their infrastructure resources; increase their applications' scalability and reduce costs. This boost in demand for cloud services led to the need for clouds to federate, in order to flawlessly deliver the required computation power and other services. In addition, there is major trend in delegating identity management tasks to identity providers in order to reduce cost. Managing identity and access control across different domains is a challenge. This paper proposes a framework for managing identity in federated clouds based on the use of a Security Assertion Markup Language (SAML) Agent. The agent acts as an interface for a cloud identity manager where it sends and receives identity assertion requests from and to other clouds in the federation. In addition, the agent assigns roles to users using identity attributes received in assertions and cloud's internal role mapping rules. For testing the agent's capability to scale and sustain load, a prototype implementation was developed. Performance evaluation results demonstrate the viability of the proposed framework.
