摘要：A worm is a self-replicating virus that does not alter files but resides in active memory and duplicates itself. Computer virus or Worm can spread to hard disk whenever an infected computer program or system is used and the uninfected disk is accessed. Viruses or Worms are transferred between computer systems using various methods; a special virus C-Worm is different from traditional worms because of its ability to intelligently manipulate its scan traffic volume over time. The proposed project analyzes the characteristics of the C-Worm and conduct a comprehensive comparison between its traffic and nonworm traffic. The project uses the Power Spectral Density (PSD) distribution of the scan traffic volume and its corresponding Spectral Flatness Measure (SFM) to distinguish the C-Worm traffic from background traffic. Extensive performance evaluations on our proposed spectrum-based detection scheme and effectively detecting not only the C-Worm, but traditional worms as well and prevention of C-Worm using mathematical model
