An intrusion detection system against UDP flood attack and ping of death attack (DDOS) in MANET
DDoS is one of the serious attacks in the ad hoc network. Among lot many DDoS attacks, UDP flood attack and Ping of death attack are considered to be important as these two attacks may cause severe damage to the network. To provide better security to the network, efficient intrusion detection (IDS) system is required to monitor the network continuously, keeping track of malicious activities and policy violations and produce report to the network administrator. UDP flood attack and ping of death attack are given importance in this paper as they are not well addressed in the existing research works. Packet capture and packet decoder is used to identify the packets and retrieve the packet details. A threshold is set for each node that is connected to the network. If the packet flow into the node exceeds the threshold that is set then the administrator is notified about the same.
