The propagation model of P2P worms can reflect the worm behaviors and identify weakness in the worm propagation which gives guidelines to worm detection and defense. To improve the security of P2P network, a mathematical model is proposed which combines dynamic quarantine and P2P churn. The SIQRW model departs from previous P2P worm models in that considering the dynamic quarantine methods and the...
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...
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...
High efficient and real-time characteristic of the signature-based approach guarantee the early detection of most known worms; while behavior-based approach searches for communication pattern of worms in accordance with their behavioral characteristics that are different from normal network traffic. To improve the detection rate and accuracy, two detection algorithms for diffuse type communication...
With more and more worms plunge into the Internet, worm-anti-worm (WAW) becomes a new active countermeasure. In this paper, a new P2P-based anti-worm is proposed. To illustrate the propagation of worms and anti-worms, TF-SEI (two-factor-SEI) model is given. By comparing our model with the traditional anti-worm model, we observe that the worm-infected hosts can approach to zero with shorter time in...
Based on pure P2P principle, a potential propagating approach of active worm which can achieve fast and self propagation performances through fragmentation mechanism is proposed in this paper. According to the features of P2P and active worm, SEI and SEIR mathematic models are given to describe the dynamical process of propagation without control and under control respectively. Simulations of these...
