How to implement DDoS attack in ns3

To Implement a Distributed Denial of Service (DDoS) attacks in ns3, we need to configure the network topology with multiple attacking node that transfer an enormous amount of traffic to a target node. Here are the procedures on how to implement the DDoS attacks in ns3:

Step-by-Step Implementation:

1. Set Up ns3 Environment:
   • Make sure ns3 is installed
   • Include all required libraries.
2. Create a New ns3 Script:
   • Create a new script file in the scratch directory of ns3, e.g., ddos_attack.cc.
3. Include Necessary Headers:
   • Include the necessary ns3 headers in your script.
4. Define Network Topology:
   • Configure a network topology that contains multiple attacker nodes and one victim node.
5. Install Applications:
   • To simulate the DDoS attack by downloading traffic-generating applications on the attacker nodes.
6. Run the Simulation:
   • Set the simulation time and run the simulation using Simulator::Run() and Simulator::Destroy().

Example

Here, we provide sample reference for DDoS attacks in ns3:

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/point-to-point-module.h”

#include “ns3/applications-module.h”

using namespace ns3;

NS_LOG_COMPONENT_DEFINE (“DDoSAttack”);

int main (int argc, char *argv[])

{

// Set up logging

LogComponentEnable (“DDoSAttack”, LOG_LEVEL_INFO);

// Create nodes

NodeContainer attackerNodes;

attackerNodes.Create (5); // Create 5 attacker nodes

NodeContainer victimNode;

victimNode.Create (1); // Create 1 victim node

// Create point-to-point links

PointToPointHelper pointToPoint;

pointToPoint.SetDeviceAttribute (“DataRate”, StringValue (“5Mbps”));

pointToPoint.SetChannelAttribute (“Delay”, StringValue (“2ms”));

NetDeviceContainer devices;

for (uint32_t i = 0; i < attackerNodes.GetN (); ++i)

{

devices.Add (pointToPoint.Install (attackerNodes.Get (i), victimNode.Get (0)));

}

// Install the internet stack

InternetStackHelper stack;

stack.Install (attackerNodes);

stack.Install (victimNode);

// Assign IP addresses

Ipv4AddressHelper address;

address.SetBase (“10.1.1.0”, “255.255.255.0”);

Ipv4InterfaceContainer interfaces = address.Assign (devices);

// Install applications on attacker nodes

uint16_t port = 9; // Discard port (RFC 863)

for (uint32_t i = 0; i < attackerNodes.GetN (); ++i)

{

OnOffHelper onoff (“ns3::UdpSocketFactory”, InetSocketAddress (interfaces.GetAddress (i + 1), port));

onoff.SetAttribute (“DataRate”, StringValue (“1Mbps”));

onoff.SetAttribute (“PacketSize”, UintegerValue (1024));

onoff.SetAttribute(“OnTime”,StringValue(“ns3::ConstantRandomVariable[Constant=1]”));

onoff.SetAttribute(“OffTime”,StringValue(“ns3::ConstantRandomVariable[Constant=0]”));

ApplicationContainer app = onoff.Install (attackerNodes.Get (i));

app.Start (Seconds (1.0));

app.Stop (Seconds (10.0));

}

// Install a packet sink on the victim node to receive packets

PacketSinkHelpersink(“ns3::UdpSocketFactory”, InetSocketAddress (Ipv4Address::GetAny (), port));

ApplicationContainer sinkApp = sink.Install (victimNode.Get (0));

sinkApp.Start (Seconds (0.0));

sinkApp.Stop (Seconds (10.0));

// Run simulation

Simulator::Run ();

Simulator::Destroy ();

return 0;

}

Explanation:

At this point, we provide the descriptions for the process that are

1. Nodes and Links:
   • Created 5 attacker nodes and 1 victim node.
   • Configured point-to-point links between each attacker node and the victim node.
2. Applications:
   • Used OnOffHelper to generate traffic from attacker nodes to the victim node.
   • Set a high data rate and constant on-time to simulate a DDoS attack.
   • Installed a PacketSink on the victim node to receive and log incoming traffic.
3. Running the Simulation:
   • The simulation runs for 10 seconds, during which the attacker nodes send continuous traffic to the victim node.

Finally, we had learned about how DDoS attacks implemented and executed in ns3 simulation tool. We also provide and support further information about how DDoS attacks implement in other tools.

We share original project ideas on Distributed Denial of Service (DDoS) attacks in ns3 simulation.
