Type Based Network Isolation Against Net Virus

The rapid development of the network brings out a large number of network viruses. The connectivity and collaboration advantages of network should be make full use in preventing against network virus. The existing isolation tools focusing on protecting the specific sub network do not fit to prevent Web-wide net virus. The paper divides the network connection into sub connections with different types and presents type-based isolation wall against net virus. The isolation wall is defined as a set of binary relation from the infected area to the susceptible area. Then the paper discusses the impact of the isolation wall on the network. Simulation test is carried out for the isolation wall. The results prove the type-based isolation in the paper is valid and causes less impact on the network which opens a new way to prevent the net viruses.
