International Journal of Computer Science Trends and Technology (IJCST) – Volume 5 Issue 2, Mar – Apr 2017RESEARCH ARTICLEOPEN ACCESSDetection of ICMP Flood DDoS AttackHarshita [1], Ruchikaa Nayyar [2]Department of Information TechnologyIGDTUWNew Delhi - IndiaABSTRACTThe term denial of Service (DOS) refers to form an attacking computers over a network. The denial of service attack is anexplicit attempt by an attacker to prevent the legitimate users not to access the services. When this attack is made at a largeramount that is by using multiple computers than it’s known as Distributed Denial of Service Attack (DDoS) [1]. An attackercan use many techniques for denial of service like flooding technique is to flood a network and reduce the legitimate userbandwidths to disrupt the services of the users. In DDoS attack, the attacker try to interrupt the services of a server and utilizesits CPU and Network. Flooding DDOS attack is based on a huge volume of attack traffic which is termed as a Flooding basedDDOS attack. Flooding-based DDOS attack attempts to congest the victim's network bandwidth with real-looking but unwantedIP data. Due to which Legitimate IP packets cannot reach the victim because of lack of bandwidth resource [5]. ICMP FLOODinitiated by sending a large number of ICMP packets to a remote host. As a result, the victimized system’s resources will beconsumed with handling the attacking packets, which eventually causes the system to be unreachable by other clients. In thisresearch firstly, we detect the ICMP Flood by using various methods and tools and find out what are the different parameters onwhich ICMP flood DDoS attack happens.Keyword:- Denial of Service (DoS), Distributed Denial of Service (DDoS), ICMP, Echo Request.I. INTRODUCTIONDenial of Service Attack (DoS) and Distributed Denial ofService Attack (DDoS) have become a major threat to presentcomputer networks. DDoS is a kind of attack in whichattacker target the victim network resources such asbandwidth, memory etc. so that victim may stop respondinglegitimate users [2]. DoS and DDoS attacks attempts to makea machine unavailable for the authorized users. In DoS orDDoS attacks attacker used to send bogus requests to intendedusers to make the services unavailable to the authorized usersor just crashes the system means attacker used to overload orflood the target machine. DDoS attacks are a global threat andnot limited to any specific industry verticals. The largestDDoS attack of 2015 was measured more than 240 gigabitsper second and persisted for 13 hours. [15]A. The main purpose to perform DDoS attack is to effectthe following are1) Consumption of computational resources, such asbandwidth, disk space, or processor time.2) Disruption of configuration information, such asrouting information.3) Disruption of state information, such as unsolicitedresetting of TCP sessions.4) Disruption of physical network components.B. DDoS attacks are divided mainly into three types1) Volume based attacks: Volume based attacks includesUDP, ICMP flood attack. In this attack, attacker’s aim is toISSN: 2347-8578Saturates the bandwidth of the victim’s side. Here bandwidthmeans the no of data or packets send per second. So thebandwidth of attacker must be higher than bandwidth of thevictim. Bandwidth is measured in bits per second. [6]2) Protocol based attack: Protocol attack includes SYNFlood, Ping of Death attack, Smurf Attack. In this type ofattacks attacker used to consumes the actual resources ofserver and this is measured in packet per second. [6]3) Application Layer attacks: The goal of Applicationlayer attack is to crash the web servers means consumes theapplication resources or services making it unavailable toothers or legitimate users. These attacks are very hard todetect and mitigate. Magnitude is measured in request persecond. [6]In a DDoS Attack many applications pounds the targetbrowser or network with fake requests that makes the system,browser, network or the site slow, useless and disabled orunavailable. DDoS attack mainly focuses on the exhaustion ofnetwork, services resources and applications therebyrestricting the legitimate users from accessing their system ornetwork resources.C. Techniques of DDoS attackThere are many techniques are used to overload a systemthese are given below.1) Bandwidth Consumption: In bandwidthconsumption many techniques are used i.e.Many/large packets, ICMP flood, UDP Flood, Forgesource address2) SYN Flooding Attackswww.ijcstjournal.orgPage 199

Internet Control Message Protocol FloodICMP is a flooding attack. In ICMP flood attacks, the attackeroverwhelms the targeted resource with ICMP echo request(ping) packets, large ICMP packets, and other ICMP types tosignificantly saturate and slow down the victim's g.1 ICMP Flood attackICMP stands for Internet Control Message Protocol. It’smostly used in networking technology. ICMP is aconnectionless protocol. ICMP mainly used for diagnosticpurposes, error reporting or querying any server but nowattackers are using ICMP protocol for sending payloads. TheICMP Flood –the sending of an abnormally large number ofICMP packets of any type can overwhelm the target serverthat attempts to process every incoming ICMP request.An Internet Control Message Protocol (ICMP) flooding attack(Schubaet al., 1997) comprises of a stream of ICMP ECHOpackets generated by the attackers and aimed at the victim.The victim replies to each ICMP request, consuming its CPUand network resources. The Smurf Attack (Alomariet al.,2012) is a reflector attack. The attacker directs a stream ofICMP ECHO requests to broadcast addresses in intermediarynetworks, spoofing the victim’s IP address in their sourceaddress fields. A multitude of machines then reply to thevictim, overwhelming its network.E. ICMP packet formatFig.2 ICMP packet formatIn the given below ICMP format the first two columnsdetermine whether an ICMP query message or an errormessage. ICMP error messages are not sent in response to anICMP error. When an ICMP error is sent, it always sends theIP header and the datagram that caused the error. So thereceiving unit gets to associate the error with the process. Sowhen a type 0 (echo reply) is sent, the reply will no longer bea Type 8 (echo request).The last field of the ICMP format talks about thechecksum. This field is used for error checking. Before anICMP message is transmitted, the checksum is computed andis inserted into the field. So at the receiving end the checksumis calculated again and verified against the checksum field. Ifany mismatch is found, then it confirms that an error orchange has occurred.F. PING commandPING stands for Packet Internet Groper. It is the commandwhich is used for testing the connection between two networknodes by sending packets and nothing in response. Nodes canbe in any connection LAN, MAN, WAN. We can ping bothwith IP address and domain name. Format of Ping commandis: Ping domain name/IP address Ping operates by sending Internet Control Message Protocolecho request packet to the server and waits for the reply. TTLvalue stands for time to live. The standard TTL value canreduce up to 30. If the number of routers between host anddestination increases by 30 then its time out.G. How ICMP flood DDoS attack happens:ICMP Flood attacks exploit the Internet Control MessageProtocol (ICMP), which enables users to send an echo packetto a remote host to check whether it’s alive. More specificallyduring a DDoS ICMP flood attack the agents send largevolumes of ICMP ECHO REQUEST packets (‘‘ping’’) tothe victim. These packets request reply from the victim andthis has as a result the saturation of the bandwidth of thevictim’s network connection. During an ICMP flood attackthe source IP address may be spoofed. Attacker use IPspoofing in order to hide their true identity, and this makes thetrace back of DDoS attacks even more difficult.1) Practical demonstration of ICMP flood: Here wetook 3 machine where 2 are virtual machine and 1physical machine. Windows 8 as current machine.Kali Linux as Attacker machine. Windows 7 astarget machine. To carry put ICMP flood we need towrite a command hping3 - -flood –V –i eth0 IPaddress of target machine DDoS Implementation:Check the network utilization of system beforeISSN: 2347-8578www.ijcstjournal.orgPage 200

RELATED WORKAs research is going on how to avoid DDoS attacks but thereare currently no successful defence against DDoS attack. Butthere are numerous safety measures that can be taken by thehost to prevent DDoS flooding attacks. Attack preventionmethods try to stop all Well Known signature based andbroadcast based DDoS attacks from being launched in the firstISSN: 2347-8578place or edge routers, keeps all the machines over Internet upto date with patches and fix security holes. Attack preventionschemes are not enough to stop DDoS attacks because thereare always vulnerable to novel and mixed attack types forwhich signatures and patches are not exist in the database.According to Sandeep, Ranjeet, in “study measure of DOS &DDOS”- Smurf Attack and Preventive measures configureindividual host and routers not to respond to ping requests orbroadcasts [1]. In the article, titled “DDA- An approach tohandle DDOS attack”, authors conducted the survey aboutDDoS attack. They discussed the various kind of DDoS suchas protocol based, volume based, Application layer based [2].A survey of defence Mechanisms against Distributed Denialof Service Flooding attack, uses hop count filteringmechanisms. In this mechanism, information about a sourceIP address and its corresponding hops from the destination arerecorded in a table at destination site when the destination isnot under attack. Once the attack alarm is raised, the victiminspects the incoming packet’s source IP address and theircorresponding hops to differentiate the spoofed IP packets [4].History-based IP filtering (HIP) is another filteringmechanism that has been proposed by Peng et al in order toprevent DDoS attacks. If we use History-based IP filtering,and if the attacker knows that the IP packet filter is based onprevious connections, they could mislead the server to beincluded in the IP address database. Victim can filterBandwidth attack traffic according to the history they hadmade. However any large Scale DDOS attack that cansimulates normal traffic behaviour will defeat suchMechanism [5]. According to M.A. Vinoth kumar and R.Udaya kumar, Identifying and Blocking high And low rateDDOS ICMP Flooding, they formed an algorithm in which ifHigh rate DDOS algorithm if (I Rate A Band) Block IP andPort Alert DDOS attack to all IPS. But the limitation is wecannot block ICMP port no because ICMP Port no is 0. ICMPdo not use any port number [12]. ICMP trace back has beenproposed by Bellovin, according to this mechanism everyRouter samples the forwarding packets with a low probability(1 out of 20,000) and Sends an ICMP trace back message tothe destination. If enough trace back messages are gathered atthe victim, the source of traffic can be found by constructing achain of Trace back messages. A major issue of this approachis the validation of the trace back Packets. Although the PKIrequirement prevents attackers from generating false ICMPTrace back messages, it is unlikely that every router willimplement a certificate-based Scheme. We can setup ourserver to ignore the pings so that our server won’t consumeBandwidth replying the thousands of pings that the server isreceiving [8]. According to “DDoS Attack Algorithm usingICMP flood”—researcher proposed an algorithm in whichthey use different perimeters. It has been tested in virtuallysimulated environment using 5 virtual machines connected tolocal ISP broadband network connection. This algorithmassumes that attacker and the victim present on the samenetwork. To perform the DoS attack they use differentparameters. 1. No. of packets. 2. Packet size. 3. No ofmachines required for attack. 4. IP address of target machine.www.ijcstjournal.orgPage 201

International Journal of Computer Science Trends and Technology (IJCST) – Volume 5 Issue 2, Mar – Apr 2017But researchers already define the number of machines theyuse i.e.5, but we can’t predefined number of machines, itdepends on bandwidth of data. [13]However, this research work is based on detecting the ICMPecho request that can cause flooding attack and based onanalysis have to limit the bandwidth of the ICMP packet ifbandwidth of an attacker is lesser than the target than noattack takes place. So we have to limit the bandwidth of theICMP packet. So we can limit the threshold value up to 1000bits/sec, if any ICMP packet exceeds this value than routerwill discard this value with its own.III.Fig. 6 Government sitesMETHODOLOGYIt is a process to proceed towards my research.

ICMP creates andsends messages to the source IP address indicating thata gateway to the Internet that a router, service or host cannotbe reached for packet delivery. Any IP network device has thecapability to send, receive or process ICMP messages. Butnow-a-days attacker uses ICMP packet for attack purpose.Attacker sends ping request to victim machine to checkwhether the victim machine is alive or not. If machine is alive,then reply back otherwise RTO. Attacker gathers manyinformation from ping command i.e. Victim machine IPaddress, O.S, Default packet size. Attacker uses theseparameters for DDoS attack. Attacker send the abnormalsequence of ICMP packets to the victim machine to choke it.The future scope is to propose an algorithm using the up givenparameters for the ICMP flood DDOS Detection.ACKNOWLEGMENTThis study is proposed by reviewing different research papersand after reviewing them we got new idea for detecting ICMPflood DDoS attack by exploring the new parameters.REFRENCES[1] [1]Sandeep, Ranjeet,A study measure of DOS &DDOS- Smurf Attack and Preventive measures,International Journal of Computer Science andInformation Technology 2014[2] Virendra Kumar yadav ,Munesh Chandra Trivedi,B.M Mehtre, DDA an approach to handle DDOS(Ping flood) Attack, Journal of Computer science2014.[3] Ankita Mangotra, Vivek Gupta, Review paper onDDoS, International Journal of Advances in ScienceandTechnology (IJAST) Volume 2 Issue3(September 2014).[4] Samantaghavi Zargar, James Joshi, David Tipper, ASurvey of Defence mechanism against DDOSFlooding Attacks, IEEE Communication survey2013.[5] Kartikey Agarwal, Dr. Sanjay Kumar Dubey,network Security: Attacks and Defence, InternationalJournal of Advance Foundation and Research inScience & Engineering (IJAFRSE) Volume 1, Issue3, August 2014.[6] Shakti Arora, Arushi Bansal, Survey on preventionMethods on DDoS Attacks, International Journal ofAdvance Research in Computer Science andSoftware Engineering, Volume 4 Issue 7 July 2014.[7] Khadijah Wan Mohd Ghazali and Rosilah HassanISSN: 2347-8578.www.ijcstjournal.orgPage 205

Denial of Service Attack (DoS) and Distributed Denial of Service Attack (DDoS) have become a major threat to present computer networks. DDoS is a kind of attack in which attacker target the victim network resources such as bandwidth, memory etc. so that victim may stop responding legitimate users [2]. .

1.2 DDoS attack characteristics DDoS attacks involve using a large number of devices to flood a victim. With an increased number of exploited machines, the amount of resources available to the attacker is far higher. Some relevant DDoS attacks are: HTTP flood: simple attack but requires a large number of resources. An attacker

ICMP is often used to determine if a computer in the Internet is responding. To achieve this task, an ICMP echo request packet is sent to a computer. If the computer receives the request packet, it will return an ICMP echo reply packet. In a smurf attack, attacking hosts forge ICMP echo requests having the victim's address as the source address and
