Distributed denial of service (DDoS) attacks on the Internet have become an immediate problem. As DDoS streams do not have common characteristics, currently available intrusion detection systems (IDS) cannot detect them accurately. As a result, defend DDoS attacks based on current available IDS will dramatically affect legitimate traffic. In this paper, we propose a distributed approach to defe...

This is undoubtedly what happened among staphylococci in the early days of penicillin. When exposure to a drug-antibiotic or synthetic-is followed by resistance in a previously se...
