IP spoofing is one of the major threats in the network security. Hackers use this to hide their identity or to perform an attack. IP spoofing used for many attacks like denial of service, SYN flooding and man in the middle attacks etc. It is necessary to capture or block the spoofers to defend against these attacks. Different IP traceback mechanisms are used for finding the spoofers identity. There is still not a widely supported mechanism to capture or block the spoofers because of the challenges in the deployment and cost. Here I propose a method for finding out spoofers with the help of path backscatter messages. They are ICMP error messages triggered by spoofing traffic helps to find the location of the spoofer based on the available information. By this method we can find the malicious node in the network .A trust based mechanism is proposed to mark this as a malicious node and isolate it from the network. And this node will not be taken for further communications in the network. This can be done with the help of the internet service providers (ISP) of the network. By using the path backscatter and trust value it may be the most useful mechanism to block spoofers and securing the network.
