  7. Abstract:
  8. attacks have become such a serious problem that according to the recent security firms’ reports, more than five thousands attacks are launched per day, whichcould lead to lots of damage and loss of online businesses. When a P2P system has millions of concurrently active peers, there is the risk that an attacker misuses these clients, or diverts their generated traffic to launch DDoS attack.As we will see, since BitTorrent has gained more popularity among other P2P protocols,and ithas the most number of concurrent active users,it may lead to destructivedamagesif exploited by attackers for lunching DDoS attack. Thus, we have focused on DDoS detection over this protocol.In this study, first,we have implementedcurrent DDoS techniques by exploiting BitTorrent network, and after that wehave introduced a crawler-based detection mechanism that is able to act more efficiently in comparison to most of the existing prevention methods without changing the protocol or client/server side’s programs, neglecting whether participating peers use protocol encryption or not. Wehave simulated P2P DDoS attacks and DDoS detection inan environmentconsists of severalcustomized virtual machines. Generally, this crawler will detect P2P DDoS attacks by crawling swarmsand evaluating peers’ reaction in response to some BitTorrenthandshakes.In comparison to other conventional approaches in collecting peers, we have used some new approaches to provide the crawler with moreparticipating peers. All used techniques, have helped this crawler to gain satisfactory resultsin detecting DDoS attacks, over the BitTorrent network
