Examples of Mimic Defense Application

Abstract

As the hub node of the Internet facility, the router decides on the packets forwarding path through network calculation to achieve end-to-end data transmission. It is a basic element of cyberspace; covers the core layer, convergence layer, and access layer of the entire network; and connects multiple heterogeneous networks. Therefore, its service reliability and credibility are crucial for cyberspace security. However, the current router security is not optimistic at all. Snowden revealed that “the US National Security Agency is monitoring Chinese networks and hosts through Cisco routers” [1]. The National Computer Network Emergency Response Technical Team/Coordination Center of China (known as CNCERT or CNCERT/CC) analyzed the routers of mainstream vendors, like Cisco, Linksys, NETGEAR, Tenda, and D-Link, confirming the existence of preset backdoors in their products. The investigation shows severe security problems with the routers.
