Worms: How to stop them?

While a very short paper, it covers an approach that is quite common, namely accurate network worm detection.

These days, networked computers are omnipresent in our day-today life. Their importance in world security in light of recent events related to terrorism is unprecedented. There is no need to belabor the potential havoc that a malicious hand can fix on our lives, upon gaining access to critical computer installations of defense systems or the Internet. Therefore such infrastructure should be protected from being compromised by villains. One of the various ways in which computer systems can be compromised is by deploying a worm.

This research deals with issues such as, when to "cry worm!", proposes models to stop their spread without human intervention, provides simple mathematical models for the proposals, if possible, and provides simulations to test the proposed models. This paper gives a concise overview of the proposed model and shows some of the prelimenary results of the simulations developed.
