SAVE AND SECURE DATA ON CLOUDS

Sonia Verma and Amit Kumar Chaudhary

The use of cloud computing has increased rapidly in many organizations. Cloud computing provides many benefits in terms of low cost and accessibility of data In the cloud environment, resources are shared among all of the servers, users and individuals. So it is difficult for the cloud provider to ensure file security. As a result it is very easy for an intruder to access, misuse and destroy the original form of data.. Ensuring the security of cloud computing is a major factor in the cloud computing environment, as users often store sensitive information with cloud storage providers but these providers may be untrusted..A movement towards “multi-clouds”, or in other words, “interclouds” or “cloud-of-clouds” has emerged recently. This paper surveys recent research related to single and multi-cloud security and addresses possible solutions. This work aims to promote the use of multi-clouds due to its ability to reduce security risks that affect the cloud computing user. In this paper, we discuss security issues for cloud computing and how to secure the data over the network. So that user can build trusted applications from untrusted components will be a major aspect of secure cloud computing.
