Data security in cloud computing

Cloud computing is a blossoming and rapidly evolving model, with new features and capabilities being announced regularly. Security of cloud-based applications and data is one of the key concerns of cloud customers. Secure software and secure software life cycle management are fundamental to the protection of cloud services. The information security of cloud systems rest on the classical principles of confidentiality, availability, and integrity, but applied to distributed, virtualized, and dynamic architectures. This paper presents an analysis of data security issues in a cloud environment. Solution exist for a few. Analysis of these solutions can be used to determine the lacunae in the data security issues.
