Abstract


In response to a variety of network security threats , network security solutions have been developed , firewall, anti-virus technology , intrusion detection , virtual private network technology, honeypot / honeynet technology . Honeypot / honeynet technology belongs to the category of active defense , \captured . Honeynet is to use multiple honeypot constitutes a hacker trapping network architecture . Traditional Honeynet technology for the camouflage of the host operating system has been more mature , but still larger defects due to the constraints of the hardware conditions on network features camouflage . In this paper, the network processor has a powerful network packet processing capabilities as the Honeynet gateway , the Honeynet network efforts to improve the ability to camouflage . First in the introduction part of the main features of the computer network topology and performance analysis, network camouflage system based on network processor built on this basis , leads to the system to use when making network masquerading several key technologies : routing lookup algorithm , routing protocols , network performance camouflage, network equipment operating system camouflage . The third chapter of the actual hardware configuration of the network processor board routing lookup algorithm selection are discussed ; fourth chapter discusses several technical points required by the OSPF routing protocol on the network processor , including the LSA database , regional , interface state machine and the neighbor state machine ; Chapter current QoS system and strategy brief introduction, combined with the characteristics of network processor computing a RED algorithm implementation ; sixth detail in Chapter remote operating system detection methods , as well as packet types may be used , on this basis, leads disguised means of network equipment ( routers and switches) OS fingerprinting ; in the end of the six chapters previously discussed several technical points were verified by experiments.
