With the emergence of cloud computing being the new trend in information technologies, it has posed a serious threat to the security, resulting in the deterioration of the effectiveness of traditional protection mechanisms. No standard security model or framework can be found in cloud computing when it deals with the transmission of sensitive data and critical applications. Due to the security reasons in cloud computing environment, the users have lost their trust in cloud. There are various security issues in cloud computing like multi- tenancy, elasticity, Security Performance and Optimization, etc. Some of the issues will be reviewed in this paper. This paper will also discuss the existing security techniques in order to secure cloud and make the researchers and professionals aware about various security threats.

Cloud Computing, Security Issues, Security Techniques.
