Research and Implementation of Firewall System Based on SNS Attributes

With the development of social information technology, there have been more and more services and applications deployed based on Social Network Web Services (SNS). Since traditional traffic classification based on protocols and ports cannot classify the HTTP based web service. And users of different applications cannot be classified by this way as well, which raises new challenges for traditional network security protections. A firewall filtering method based on SNS attributes model was put forward in this paper. On the basis of this method a SNS attributed firewall architecture was also developed. By analyzing the data of application layer we can specify the SNS user identification and realize access control from user to applications.
