In this paper, a delayed worm propagation model with birth and death rates is discussed. The number of system reinstallations may be increased when the hosts get unstable (infected or quarantined). In view of such situation, dynamic birth and death rates are introduced. Afterwards, the stability of the positive equilibrium is studied. Through the theoretical analysis, it is proved that the model is...
Due to the vulnerability of computer system, Internet worm is still greatly threatenning network security. It is found that the spread of worm regularly change because of the different space distributions of hosts and this phenomenon is defined as diurnal pattern. Based on diurnal pattern, two worm propagation models, namely simple diurnal forced model and complicated diurnal forced one, are constructed...
In this paper, a worm propagation model with pulse quarantine strategy is proposed to control the spread of the worm. This model which combines both the pulse quarantine and the constant quarantine strategy not only describes the propagation of the worm well and but also makes the infections eradicated effectively. Here, we show that there exits a stable infection-free periodic solution of the system...
A chaotic worm propagation model is proposed to analyze early worm propagation process in this paper. Worm propagation is very complex, whose major transitions are between regular cycles and irregular, possibly chaotic epidemics. This paper deals with a discrete mathematical model of early worm propagation systems: Chaotic Susceptible-Infected (CSI) model. In the CSI model, three threshold values...
P2P worm based on loopholes spreading in peer-to-peer network is a serious security threat. According to the characteristics of P2P worms, a signature-behavior-based P2P worm detection approach detecting the known P2P worm based on characteristic string matching is proposed. In addition, this method can also detect unknown P2P worms based on behavior. This method is mainly composed of the technology...
Due to the features of interaction between malicious codes, the cooperation becomes more and more common. In this paper, cooperation between worm and virus is discussed in detail, and a cooperation model named CM model is proposed to describe the dynamical process of propagation. Results of simulation and mathematic analysis show that the propagation performance is significantly improved with the...
We proposed a worm detection and defense system named bot-honeynet in this paper, which combines the best features of honeynet, anomaly detection and botnet. The combination of honeynet and anomaly detection system offers a tradeoff between false positive and false negative rates. The control mechanism of botnet can help our system control all the honeypots in the bot-honeynet. Bot-honeynet is designed...
