Research on Building the Credibility Evaluation's Indicator System of Cloud End User’s Behavior

The development of cloud computing technology and the popularization of cloud services have a great impact on the industry. On the one hand, cloud technology enhances network's operation efficiency and reduces the cost. On the other hand, the cloud resource can be accessed by any network equipment. It increases the chances that the identity of user is misrepresented and then led to many security problems. Therefore, the actual needs of security can't be fully satisfied with controlling the malicious user access to the cloud resource by login authentication that relies solely on current user identity. User is the requester and provider of cloud resources. User behavior's credibility relates to the safety of cloud directly. So it's very important to evaluate user behaviors whether it can be trusted or not on cloud. In this paper, we studied influence factors of user behavior credibility based on behavior data analysis and then carried on a thorough discussion about evaluation indicators of user behavior credibility.
