STUDY ON SECURITY MODEL IN CLOUD COMPUTING

Abstract

Cloud computing is new and latest trend in Information Technology for dynamic provisioning of IT capabilities. Cloud services require addressing the security during the transmission of sensitive data and critical applications to shared public cloud environments. In cloud computing there is no standard security model and framework. According to the study of various cloud security models as CSA model, Jerico forum's model, NIST Cloud Reference architecture, cloud multi-tenancy model, and NIST formal model, we have proposed a new cloud security model which has authentication through verification and validation, security components such as OTP, 2FA, and security policies- through guidelines, procedures and security controls- through privilege control.
