The countless advantages of cloud computing has brought a massive change to the lifestyle and the way to cope with the world today, yet the cloud has to reach maturity. However, the main barrier to its widespread adoption is the security and privacy issues. In order to create and maintain mutual trust among the customers and the cloud service providers, a well – defined trust foundation should be implemented. The data stored in the cloud remotely by individual customer or an organization, so they lost control over the data, thus creating a security dilemma. The most challenging and hot research area in cloud computing now a day is the data security and access control. An effective measure to protect cloud computing resources and services in the start is to implement an access control mechanism. In this paper the features of various access control mechanisms are discussed and a novel framework of access control is proposed for cloud computing, which provides a multi - step and multifactor authentication of a user. The model proposed is well-organized and provably secure solution of access control for externally hosted applications.
