Abstract: In order to ensure the security of cloud computing environment, a multi-level?intrusion detection model for?cloud computing based on immune algorithm is proposed. In view of the cloud architecture, non-adaptive immune layer is deployed in the user terminal, and the detection of risk of intrusion behaviors is carried on based on the dendritic cell algorithm; adaptive immune layer and immune memory layer are deployed in the data center of a cloud computing. Using the improved dynamic clonal selection algorithm the known and unknown intrusion behaviors are identified and resisted. The experimental results show that the model can both resist the invasion behaviors and conduct real-time monitoring of the entire cloud computing environment, is an effective cloud computing security model.
