Cloud computing environment is a new way in which web base enable applications provide as a service for the users with low computational cost through internet. As we store data and it also provide services in distributed environment. Cloud ease its users by providing virtualization technology of resources through internet. Cloud computing is the emerging field, due to this reason the various new techniques are still developing. At current scenario new security challenges were increases for cloud professionals. Due to lack of security in cloud computing environment user of cloud lost it trust in cloud. Multi-tenancy, elasticity, Security Performance and Optimization, etc. are various security issues in cloud computing. In this paper we will discuss some of the issue in cloud. This paper also discusses some of the existing security technique for securing a cloud and help researchers and professionals to know about various security threats.
