| Abstract(in English) | DDoS (Distributed Denial of Service) is one of the illegal accesses. The attackers send a high volume of attack packets from a large number of machines distributed over various location to target server, and make it impossible to perform services for legitimate users. It is generally difficult to detect or reject of DDoS attack packets, but DDoS is one of the threats to reliability and security of the Internet. There have been some researches for prevention of DDoS attack based on signature of traffic pattern and anomaly for packet rate. In this paper, we propose packet filtering method against DDoS attack. In our method, we calculate and evaluate the posterior probability of the event that an arrival packet belongs to DDoS traffic with inter arrival distribution and distribution of packet attribute. Numerical examples show that the proposed method effciently detects attack packets among a large number of normal packet streams. |
