ABSTRACT
Data security has always been a significant matter in information technology. In the cloud computing environment, it becomes mainly severe because the data is placed in different places, even anywhere in the world. Data security and privacy protection are the most critical aspects of a user’s concerns about cloud technology. The significant difference in cloud security is that the cloud user does not control the physical system. The application of security, infrastructure, and a platform is under the provider’s control. Cloud security depends on some factors that are responsible for forming the cloud more vulnerable to threats and attacks. Thus, security can be implemented into four sections namely: Cloud Security behind the Virtualization, Securing Data over the Cloud, Cloud Channel Security, and Securing Cloud System Management. In this chapter, the discussion is about the factors leading to cloud being vulnerable to threats and attacks and also on the methods and solutions to make secure cloud system.
