Abstract
A Distributed denial of Service attacks(DDoS) is one of the major threats in the cyber network and it attacks the computers flooded with the Users Data Gram packet. These types of attacks causes major problem in the network in the form of crashing the system with large volume of traffic to attack the victim and make the victim idle in which not responding the requests. To detect this DDOS attack traditional intrusion detection system is not suitable to handle huge volume of data. Hadoop is a frame work which handles huge volume of data and is used to process the data to find any malicious activity in the data. In this research paper anomaly detection technique is implemented in Map Reduce Algorithm which detects the unusual pattern of data in the network traffic. To design a proposed model, Map Reduce platform is used to hold the improvised algorithm which detects the (DDoS) attacks by filtering and sorting the network traffic and detects the unusual pattern from the network. Improvised Map reduce algorithm is implemented with Map Reduce functionalities at the stage of verifying the network IPS. This Proposed algorithm focuses on the UDP flooding attack using Anomaly based Intrusion detection system technique which detects kind of pattern and flow of packets in the node is more than the threshold and also identifies the source code causing UDP Flood Attack.
Highlights
Distributed Denial of Service (DDOS) attack is a distributed, huge scale coordinated attempt of flooding the cyber net with an enormous amount of packets which is difficult for victim network to handle so the victim is unable to provide the services to its users and the network performance is greatly reduced
DDOS attacks are classified into different types such as HTTP flood attack, Users Datagram Packet (UDP) flood attack, ping of death attack In this research paper we have taken a type of attack UDP flooding attack which comes under the classification of distributed of denial of service
Threshold value is set for the UDP Packets, if UDP packets are exceeds the Threshold values the UDP attack will be detected
Summary
DDOS attack is a distributed, huge scale coordinated attempt of flooding the cyber net with an enormous amount of packets which is difficult for victim network to handle so the victim is unable to provide the services to its users and the network performance is greatly reduced. TCP SYN flood: This attack is caused by an attacker sends a lot of ordinary SYN segments to fill up resources causing a service to be denied for its connections In this attack huge amount of UDP packets are sent to random ports on the victims side. In this research paper the Map Reduce Improvised Counter Based algorithm is used to detect the UDP flooding attack. In Reduce phase has detection algorithm which is used to detect (Alkasassbeh, 2016)[6] the UDP Flooding attack based on the threshold value. We set the Hadoop [7]environment which has Map (Shweta Tripathi1, 2013) Reduce programming model which has two stages In first stage this algorithm which separates the UDP packets from the network. STEP 8: If UDP_PACKET > THRESHOLD Notify UDP_FLOOD_ATTACK STEP 9: Stop
