The Smart Phone Multi-function Firewall Model Design

With the development of smart mobile-phone, the kind of the business based the mobile-phone is becoming more and more.As a result, now the security about the smart mobile-phone has become a focus of the topic.Mobile security issues focused on four aspects, including the three major kinds of business that is mobile phone to send and receive business communications business message as well as mobile network business.
