According to the idea about constructing a CDC(center for disease control),the deployment and response mechanism of CDC-based benign worms are designed,with the process of using CDC-based benign worms to counteract the propagation of worms modeled and simulated.

Strategy of fast and light-load friendly worm propagating;

A diffusing balance-tree-based friendly worm propagation strategy is proposed, and the auto-generation rules and survivability enhancements are also given to account for the expansibility and the stability.

The network simulation system SSFNet is deeply analyzed and improved to meet the requirements of the study of anti-worm counter-attack.

This paper considers a new active counter-measurement called anti-worm which is also a kind of self-propagating code that can trav.

Research of policy defending against P2P worm based on benign worm

Through analyzing the characteristics of the Internet worm, considered with the topology characteristics of e-mail and P2P networks, this dissertation uses the benign worm as the major tool to study policies against e-mail worm and P2P worm in depth, main functions include:1.

First, this paper introduces three basic worms propagation models and analyzes four situations after the introduction of benign worm.

This paper proposes a new kind of anti-worm called P2P anti-worm which propagates using P2P techniques.

The mature friendly worms,memory friendly worms and bacterin friendly worms are defined based on the biological immune principles,and the uew transi- tion relations between host states are created.
