Hybrid IP Traceback Involving Path Reconstruction Using QoS
Jeevaa Katiravan, N. Duraipandian · 2014
Extensive increase in internet usage in this present situation has increased the threats to the security of the network. Illegitimate user's causes damage to the resources, thereby hindering the service rendered to the users. Defending against DoS attacks requires not only mitigating its effect but also to identify the corresponding source of attack. This process is called IP traceback. In this paper we enumerate a hybrid IP traceback involving both packet marking and packet logging. During the process of tracing back the attack source if any router or node goes down positive feedback is not possible. We use link state routing method and OSPF routing protocol to overcome such a hindrance. Also ISP (Internet Service Provider) sets constraints to monitor our network thereby identifying the attackers easily and increasing the security.
