Network Radar System

NetRadar System is an important research subject in the area of Internet Security.It's aim is to detect the foundational terminals of and the route to a certain aimed Intranet;to scan the softwares that run on the terminals;to find the services which are provided by the terminals;to determine the vulnerabilities of the services and the distribution of the vulnerabilities.Ater all the above have fmished,the NetRada system attacks the vital terminals or the vulnerable terminals and controls them automatically. The article primarily describes the implementation of the Route Detection Module of the Internet Topology Sub-System,the Internet Vulnerabilities Scanning Sub-System,and the Remote Control Module of Attack and Control Sub-System in the circumstances of Windows 2000 and the Microsoft Visual C++6.0.The article focuses on the five important technologies we used,including the Router Detection technology,the Os Identification technology, the Port Identification technology,the Trojan horse technology and the Ports-Reflection technology. The article highlights the implementation of how to detect the route to an aimed Intranet by Traceroute,how to determine the Operating System by the Tcp/Ip stacks fingerprints,how to find the users information of the common OS,how to realize the Port Scan by multi-thread, how to find the vulnerabilities of a terminal,and how to control a remote system by the Trojan horse.
