Research On Cloud Computing Risk Assessment System

In recent years,with the continuous progress of information and communication technology,information technology has been and will further affect the economic and social development of all countries in the world,at the same time changing people's production and life style.Big data continues to heat up and subvert the traditional business model.Cloud computing to accelerate the floor,network resources,business resources,user resources in the application mode to change the traditional IT architecture services.Cloud computing system of multi tenant,resource sharing,data storage and carrying non localized type of business diversification to the data center brings endless possibilities,but also brings new security challenges and risks.The risk assessment system is an important tool for system safety management,through the security identification and comprehensive risk assessment of information system,and is designed to eliminate or reduce the risk,which makes the system to reduce the risk to an acceptable level,greatly enhance the security of information system.Therefore,it has become an important method to enhance the security of the cloud computing system by using the risk assessment,which has become an important method to improve the security of the cloud computing system,and become a hot research topic in the cloud computing security.Based on the cloud computing risk evaluation system as the research object,and the common aspects of cloud computing system and around the risk assessment technology,modeling method of cloud computing system and implementation of technology tools have done a lot of research.Finally,based on AHP based cloud computing system,puts forward a risk assessment model for OpenStack cloud computing system,and on the basis of the design and implementation of a risk evaluation system for cloud computing system.The system of collecting,processing and computing of cloud computing system by monitoring information and log data,and the model checking and evaluation system for the calculation of the overall security risk assessment of the whole cloud,so as to provide decisionmaking basis for cloud computing security system.After testing and optimization,the system can be more accurate,comprehensive and realtime reflect the current security risks of cloud computing system,has an important practical significance to solve the information security problem in the new IT environment.
