摘要: It is well understood that not all vulnerabilities are or can become potential worms. However, the characteristics lead to a vulnerability being used in worm poorly described and modeled. To facilitate evaluating new announcements create descriptive risk landscape, we introduce mathematical description for vulnerability’s “wormability,” use of propagation. This model provides an interrelation between exploit required leverage vulnerability, size nature vulnerable population, time intervals publication current time, general landscape on Internet as whole. Using this model, provide measure possibility several becoming worms near-future along with explanations why some inherently “wormable.”
