With the extended SEIR model, namely E-SEIR, three aspects of information security policies (i. e., immunization, information security training,and user recovery support) are investigated in terms of their impacts on the email virus propagation. The results show that the E-SEIR model is suitable to reflect the propagation pattern of email virus, and may also be used in anti-virus policies simulation and evaluation.展开更多
