A Worm Containment Model Based on Neighbor-Alarm

摘要

How to detect and contain worms is an open issue as worm becomes a major threat to network security nowadays. Based on the help between neighbors in social network, this paper presents a model to mitigate the rapid spread of worms, and describes its dynamic equation. Since the performance of our model depends on the trust between neighbors, a method to calculate the trust is given in this paper. TPM can protect the authenticity of trust between neighbors, and thus decrease the worm propagation. Experimental results demonstrate that this model can greatly suppress the propagation of worms.
