Abstract
Cloud computing is now among the most extensively used mean for resource sharing as SaaS, PaaS, and IaaS. Computing Scenarios have been emerged into cloud computing instead of distributed computing. It has provided an efficient and flexible way for dynamic services meeting needs and challenges of the time in cost effective manners. Virtual environments provided the opportunity to migrate traditional systems to the cloud. Cloud service providers and Administrators generally have full access on Virtual Machines (VMs) whereas tenants have limited access on respective VMs. Cloud Admins as well as remote administrators also have full access rights on respective resources and may pose severe insiders threats on which tenants haven shown their concerns. Securing these resources are the key issues. In this paper, available practices for cloud security are investigated and a self-managed framework is introduced to mitigate malicious insider threats posed to these virtual environments.
