Preventive mechanism against DDoS attacks in MANET

Abstract

A prevention technique is proposed in this article against DDoS attacks which consume the bandwidth in modern MANETS. Since these networks are wireless and self-configuring and doesn't need a pre-existing infrastructure and have a large unpredictable node movements, security becomes one of the most vital issue to be raised into the account. The proposed approach is based on the analysis and investigations of bandwidth attacks that mainly focus on DDoS that is truly a ruthless challenge and is difficult to detect, and decreases the performance of the network. DDoS includes a group of attacker nodes and targets the victim to prevent the legitimate users from accessing the network services and resources. Intrusion prevention system are the procedures that are treated as Add-ons' of the intrusion detection system to actively defend and prevent the intrusions, that are detected by the detection procedures of the IDS. The report that is generated by the IDS after analyzing the report of the forensic analysis is the base of the proposed procedure.
