Abstract: It is well-known that cloud computing has many potential advantages and many enterprise applications
and data are migrating to public or hybrid cloud. But regarding some business-critical applications, the
organizations, especially large enterprises, still wouldn’t move them to cloud. The market size the cloud computing
shared is still far behind the one expected. From the consumers’ perspective, cloud computing security concerns,
especially data security and privacy protection issues, remain the primary inhibitor for adoption of cloud
computing services. This paper provides a concise but all-round analysis on data security and privacy protection
issues associated with cloud computing across all stages of data life cycle. Then this paper discusses some current
solutions. Finally, this paper describes future research work about data security and privacy protection issues in
cloud.
Keywords: access control; cloud computing; cloud computing security; data segregation; data security; privacy
protection.
I. INTRODUCTION
Cloud Computing is a distributed architecture that centralizes server resources on a scalable platform so as to provide on
demand computing resources and services. Cloud service providers (CSP’s) offer cloud platforms for their customers to
use and create their web services, much like internet service providers offer costumers high speed broadband to access the
internet. The emerging paradigm of cloud computing provides a new way to address the constraints of limited energy,
capabilities and resources. However, security and privacy protection is a critical concern in the development and adoption
of cloud computing. To avoid system fragility and defend against vulnerabilities from cyber attacker, various cyber
security tools and techniques were developed. Compared with the traditional IT model, the cloud computing has many
potential advantages. But from the consumers’ perspective, cloud computing security concerns remain a major barrier for
the adoption of cloud computing. According to a survey from IDCI in 2009, 74% IT managers and CIOs believed that the
primary challenge that hinders them from using cloud computing services is cloud computing security issues. Another
survey carried out by Garter in 2009, more than 70% CTOs believed that the primary reason not to use cloud computing
services is that there are data security and privacy concerns. In 2009, the major cloud computing vendors successively
appeared several accidents. Amazon's Simple Storage Service was interrupted twice in February and July 2009. This
accident resulted in some network sites relying on a single type of storage service were forced to a standstill. In March
2009, security vulnerabilities in Google Docs even led to serious leakage of user private information. Google Gmail also
appeared a global failure up to 4 hours. It was exposed that there was serious security vulnerability in VMware
virtualization software for Mac version in May 2009. People with ulterior motives can take advantage of the vulnerability
in the Windows virtual machine on the host Mac to execute malicious code. Microsoft's Azure cloud computing platform
also took place a serious outage accident for about 22 hours. Serious security incidents even lead to collapse of cloud
computing vendors. As administrators’ misuse leading to loss of 45% user data, cloud storage vendor LinkUp had been
forced to close.
