The Multi-fractal Nature of Worm and Normal Traffic at Individual Source Level

Worms have been becoming a serious threat in web age because worms can cause huge loss due to the fast-spread property. To detect worms effectively, it is important to investigate the characteristics of worm traffic at individual source level. We model worm traffic with the multi-fractal process, and compare the multi-fractal property of worm and normal traffics at individual source level. The results show that the worm traffic possesses less multi-fractal property.
