Emerging security challenges in cloud computing: an insight

Abstract

Cloud computing has been evolved as a new computing prototype with the aim of providing reliability, quality of service and cost-effective with no location barrier. More massive databases and applications are relocated to an immense centralized data center known as the cloud. Cloud computing has enormous benefits of no need to purchase physical space from a separate vendor instead of using the cloud, but these benefits have security threats. The resource virtualization, the data and the machine are physically absent in the cloud; the storage of data in the cloud causes security issues. An unauthorized person can penetrate through the cloud security and can cause data manipulation, data loss or theft might take place. This chapter has described cloud computing and various security issues and challenges that are present in different cloud models and cloud environment. It also gives an idea of different threat management techniques available to encounter security issues and challenges. The RSA algorithm implementation has been described in detail, and the Advance Encryption Standard policy, along with its implementation, has also been discussed. For better clarification, several reviews are conducted on the existing models.
