Abstract:

According to the characteristics of virtual machine, an exception detection strategy based on context clustering is proposed, which uses a new clustering initial center selection strategy to aggregate virtual machine instances with similar context running environment. Then, the local anomaly factor algorithm that affects space is improved incrementally, and a context anomaly detection model is constructed for each contextual cluster. The real-time acquisition virtual machine is matched to the corresponding context anomaly detection model according to the context information contained. The corresponding context anomaly detection model can incrementally detect the newly collected virtual machine instance. Several numerical experiments show that the proposed anomaly detection model and recognition algorithm are effective and efficient.
