Abstract: Breaking out of network worms brings a tremendous damage to the Internet. Launch the worm defense and response can improve network anti-strike capability. Tracing worm propagation path after its outbreak can reconstruct not only the earliest infected nodes but also the timing order of victims been infected. For the detection and defense of large scale Internet worm outbreaks, a convenient and safety experimental environment that capable of running real worm become an important work to observe large scale worm infection, intrusion and propagation, it can be a large scale worm testbed for forensic evidence. This paper presents a large-scale worm propagation experiments environment for tracing algorithm, which is an isolation environment that can run related experiments. To conform as much as really to the actual network, the experimental environment use virtual machine technology, simulate a large number of hosts and network equipments attend. According to the actual worm, this environment can trigger large-scale worm outbreaks within the controllable scope of human, observe propagation process of the worm, experiment detection and defense techniques, discover worm propagation characteristic such as scanning method and propagation process, real-time collect network traffic and propagation process, investigate network traffic, launch speculate algorithm for reconstructing out patient zero and propagation path of the worm. Then actual worm propagation process can be captured and compared with the results using tracing algorithm.
