Cloud computing is a technology that has brought revolution in IT industry because of its performance ,availability, accessibility etc.It doesn't require any new infra structure and it maximize the capacity of new personnel or licensing new software. It provides big storage for data and computation power is very fast and it is serving large amount of customers. It necessarily shift the database and application to the large data base centers which is known as cloud where data is not completely secure. Because of which companies do not prefer to deploy their business to cloud even when it offer so many things. The data security in cloud is one of the major issue we are facing in the implementation of the cloud. So we present a paper in which we provide a solution for the security of cloud.We try to give complete security i.e from the data owner to the cloud and from cloud to the user of data. We use the classification of data on the basics of 3 parameter presented by the user i.e Confidentiality (C), Integrity(I) and Availability(A).The strategy followed to protect the data utilizes various measures such as the SSL (Secure Socket Layer) 128-bit encryption and can also be raised to 256-bit encryption ,the MAC (Message Authentication Code) is used for integrity check of data, searchable encryption and division of data in cloud for storage.
