This paper presents a Cloud Computing Adoption Framework (CCAF) security suitable for business clouds. CCAF multi-layered security is based on the development and integration of three major security technologies: firewall, identity management and encryption based on the development of Enterprise File Sync and Share technologies. The paper explains the motivation, related work, and views on security framework. Core technologies have been explained in detail and experiments were designed to demonstrate the robustness of the CCAF multi-layered security. The breakdown of the paper includes literature, core technologies, multi-layered approach, and topics of discussion.
