The major way of attack in cyber world is cyber war. Cyber war is a form of war which takes places on computers and the Internet, through electronic means rather than physical ones. With an increasing global reliance on technology for everything from managing national electrical grids to ordering supplies for troops the security of cyber world become an important issue worldwide. In this paper, an e-epidemic SEIR (susceptible-Exposed-Infectious-Recovered) model for the transmission of worms in a computer network is developed to have a better understanding of the reason for Cyber war. An analysis of the basic reproduction number has been made. We derive global stability of a worm-free state. Furthermore, initial simulation results show the positive impact of increasing security measures on worm propagation in computer network. Efficiency of antivirus software and crashing of the nodes due to worms attack is critically analyzed.
