Research and Analysis of Intrusion Prevention Based on Trusted in Cloud Environment

Cloud computing has a nature of dynamic, virtualization and opening since it made. All kinds of large-scale cloud security incidents makes frequent cloud environment safety has been questioned. In order to ensure the security of cloud environments, intrusion prevention technologies trusted computing ideas proposed by combining intrusion prevention framework model based on trusted computing environment under a cloud. The model departure from the principle of intrusion prevention, access to behavioral characteristics, and then gradually normalize these features determine the weight of each feature heavy user node's credibility after the draw. Then it use a variety of cloud cluster server engine to detect defense and integrated decision analysis and cluster analysis to make timely cloud fast, and change the traditional intrusion prevention for their own business, to detect the status of the defense lag for cloud users with the maximum safe limit intrusion prevention services, but also to ensure that the cloud can withstand attacks, so the cloud and cloud users bidirectional safety effects.
