Comparative analysis on security mechanisms in cloud

Cloud computing confers benefits to its customers but regardless of all the advantages, information security is one of the major concerns on cloud paradigm. Information security challenge rises from the fact that consumer of public cloud services has no access to physical servers while utilizing different cloud services. Several security mechanisms such as access control, privacy management and trust management are used to enhance security at cloud epitome. This research discuses several techniques proposed by different researchers related to different security mechanisms for cloud platform. A brief comparison of all identified techniques is presented based on the criteria identified by National Institute of standards and technology for good practices and quality assessment of security mechanisms.
