Malware diffusion behavior analysis in the internet and its immune protection strategies

Malware has become the main threat to security of computer and networks. The Internet is the main channel for malware diffusing. According to the diffusing behaviour of malware on the Internet, this research designed a multi-agent simulation model of the malware diffusing. This model took the Internet as a complex network, distinguished large-scale nodes and general nodes in the Internet. It is studied how the autonomous general hosts´ learning ability and malware´s upgrade influence in the diffusing behaviour of malware. The results showed that ability of large-scale nodes controlling malware to diffuse and learning ability of general hosts played a decisive role in the control of malware diffusing. According to the simulation results, some immune protection strategies to resist malware are presented.
