Abstract:
Problem statement:
Distributed Denial of Service (DDoS) is a serious threat to the internet world
that denies the legitimate users from being access the internet by blocking the
service. Approach: In this study, we
proposed a novel approach, Geographical Division Traceback (GDT) for efficient
IP traceback and DDoS defense methodology. DDoS attack is one of the most
serious and threatening issue in the modern world web because of its notorious
harmfulness and it causes the delay in the availability of services to the
intended users. Results: Unless like
a traditional traceback methodology, GDT proposes a quick mechanism to identify
the attacker with the help of single packet which imposes very less
computational overhead on the routers and also victim can avoid receiving data
from the same machine in future. This mechanism for IP Traceback utilizes the
geographical information for finding out the machine which was responsible for
making the delay was proposed. The IP packet consists of the subspaces details
in which the path denotes. It helps to make sure whether the packet travels in
the network and falls within any one of the subspaces. The division of subspaces
leads to the source of attack system. Conclusion/Recommendations:
This method possesses several advantageous features such as easy traversing to
the attacker and improves the efficiency of tracing the attacker system.
Key words: Network
