Computer viruses remain the information security threat for business and result a devastating effect on business continuity and profitability. In order to deploy antivirus countermeasures, it is necessary to understand and explore the computer virus propagation. This research explored further the users who contact with media and discuss information security controls, including management and technical. First, we propose the computer viruses propagation model and analysis from system viewpoint. Second, we explore and evaluate the effectiveness of preventive countermeasures. Finally, we suggest several considerations for manager to practice. The simulation results show that users contact with media for network had a significant effect on infection rate and policy enforcement has powerful influence than firewall on restrain infection rate. Based on these results, we suggest: (1) information security management policy development takes precedence over the physical security; (2) it is very important to identify all assets, define the classification of assets, and identify security roles and responsibilities of employees; (3) it is necessary to audit regularly the configurations and the parameters of security techniques; (4) the operating system and the application software on hosts and servers should be updated and patched regularly; (5) the removable storage and removable/mobile access media should be restricted.

“…Based on the fact that some virus can infect an arbitrary vulnerable computer through random scanning, the homogeneous models regard the propagation network as fully connected, such as the 1-n-n-1 type D-SEIR malicious propagation model proposed by Mishra et al [3], SCIR model and SEIRS model proposed by Guillén et al [4,5], SLAR model by Dong et al [6], SIP model proposed by Abazari et al [7], SVEIR model proposed by Upadhyay et al [8], and SLBS model proposed by Yang et al [9,10]. Instead, the heterogeneous model assumes that the virus could only spread between the direct topological neighbors.…”

The rapid propagation of computer virus is one of the greatest threats to current cybersecurity. This work deals with the optimal control problem of virus propagation among computers and external devices. To formulate this problem, two control strategies are introduced: (a) external device blocking, which means prohibiting a fraction of connections between external devices and computers, and (b) computer reconstruction, which includes updating or reinstalling of some infected computers. Then the combination of both the impact of infection and the cost of controls is minimized. In contrast with previous works, this paper takes into account a state-based cost weight index in the objection function instead of a fixed one. By using Pontryagin's minimum principle and a modified forward-backward difference approximation algorithm, the optimal solution of the system is investigated and numerically solved. Then numerical results show the flexibility of proposed approach compared to the regular optimal control. More numerical results are also given to evaluate the performance of our approach with respect to various weight indexes.

“…Particularly the classic epidemic models, such as SIRS [3][4][5] model, SEIRS model [6], and SEIQRS model [7,8], are used to investigate the spreading law of computer viruses due to the common feature between the computer virus and the biological virus. Some computer virus models with infectivity in both seizing and latent computers have been also proposed by Yang et al [9][10][11][12][13].…”

A delayed computer virus model with antidote in vulnerable system is investigated. Local stability of the endemic equilibrium and existence of Hopf bifurcation are discussed by analyzing the associated characteristic equation. Further, direction of the Hopf bifurcation and stability of the bifurcating periodic solutions are investigated by using the normal form theory and the center manifold theorem. Finally, numerical simulations are presented to show consistency with the obtained results.
