NIST defined cloud computing as a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. Cloud computing is a new trend of computing paradigm that provides a set of scalable resources on demand. However, it also being a target of cyber attacks and creates risk for data privacy and protection. An Identity Management System (IDM) supports the management of multiple digital identities for authentication and authorization. This paper reviews various identity management frameworks that help making cloud environment more secure.
