However, the fast growth rate of such large data generates numerous challenges, such as the rapid growth of data, transfer speed, diverse data and security. This paper shows overview of big data, its characteristics, and stages involved, big data in cloud and security issues and challenges with big data, strengthen of big data security and some proposals to big data security.
