Research on the Information Security Problems in Cloud Calculation’s Environment

With the development of technology, cloud calculation becomes a widely used technology and is regarded as the third IT revolution following the computers and the Internet. Cloud calculation benefits ordinary users to enjoy high-end IT services by making it turn into the real basic resources through IT technology, resource sharing and high concentration. While cloud calculation offers a variety of convenience, it is very vulnerable to malicious attacks of stealing service or data because the cloud stores a large amount of valuable information about users' data, privacy information and so on. While dealing with cloud computing, confidential data can be secured from the unauthorized access and internal threats. Then only after resolving its security issues, it is able to operate successfully. This paper at first introduces the concept and characteristics of cloud calculation and then elaborates the current situation of cloud calculation's security. Then it analyzes the security risks of cloud calculation. In order to make use of the cloud benefits to full extent, these risks need to be addressed first. In this paper we present the major security issues in cloud computing. Some of the countermeasures that can be implemented are
