Network-Based Real-Time Connection Traceback System (NRCTS) with Packet Marking Technology

摘要

Recently the number of Internet users has very sharply increased, and the number of intrusions has also increased very much. Consequently, security products are being developed and adapted to prevent systems and networks from being hacked and intruded. Even if security products are adapted, however, hackers can still attack a system and get a special authorization because the security products cannot prevent a system and network from every instance of hacking and intrusion. Therefore, the researchers have focused on an active hacking prevention method, and they have tried to develop a traceback system that can find the real location of an attacker. At present, however, because of the Internet's diversity real-time traceback is very difficult. To overcome this problem, a traceback system is proposed in this paper that have a possibility to be adapted to the current Internet environment. The system is a Network-based Real-Time Connection Traceback System (NRCTS) that uses the packet marking technique.
