How to Start Intrusion Attacks Projects Using NS3

To Simulate Intrusion attacks in NS-3 has contains the creating a network in which malicious nodes attempt to exploit vulnerabilities, disrupt communication, or compromise data. Intrusion attacks can be involving the DoS, data interception, unauthorized access, or malware injection.

Here’s how to start an Intrusion Attack project in NS-3:

Steps to Start Intrusion Attacks Projects Using NS3

  1. Set Up NS-3
  • Install NS-3:

./waf configure

./waf build

  • Verify the installation:

./waf –run hello-simulator

  1. Understand Intrusion Attacks
  • Intrusion Categories:
    • Passive Attacks: The passive attacks are Overhearing and traffic analysis.
    • Active Attacks: The active attacks are DoS, packet injection, unauthorized data access.
  • Common Intrusion Techniques:
    • Manipulating vulnerabilities in protocols.
    • We Gaining the unauthorized access to resources.
    • The flooding a network to interrupt service.
  1. Define the Network Topology
  • Network Setup:
    • Legitimate Nodes: The generally communicating are clients and servers.
    • Attacker Node: It Performs the intrusion attacks.
  • Example Topology:

NodeContainer clients, servers, attacker;

clients.Create(2);  // Two legitimate clients

servers.Create(1);  // One server

attacker.Create(1); // One attacker

PointToPointHelper p2p;

p2p.SetDeviceAttribute(“DataRate”, StringValue(“10Mbps”));

p2p.SetChannelAttribute(“Delay”, StringValue(“2ms”));

// Connect nodes

NetDeviceContainer clientToServer = p2p.Install(NodeContainer(clients, servers.Get(0)));

NetDeviceContainer attackerToServer = p2p.Install(NodeContainer(attacker.Get(0), servers.Get(0)));

  1. Assign IP Addresses
  • Install the Internet stack and allocate IP addresses.

InternetStackHelper stack;

stack.Install(clients);

stack.Install(servers);

stack.Install(attacker);

Ipv4AddressHelper address;

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

address.Assign(clientToServer);

address.SetBase(“10.1.2.0”, “255.255.255.0”);

address.Assign(attackerToServer);

  1. Simulate Legitimate Traffic
  • Enhance the general communication among clients and the server.
  • Example: UDP Traffic

uint16_t port = 9;

UdpEchoServerHelper echoServer(port);

ApplicationContainer serverApp = echoServer.Install(servers.Get(0));

serverApp.Start(Seconds(1.0));

serverApp.Stop(Seconds(10.0));

UdpEchoClientHelper echoClient(Ipv4Address(“10.1.1.1”), port);

echoClient.SetAttribute(“MaxPackets”, UintegerValue(50));

echoClient.SetAttribute(“Interval”, TimeValue(Seconds(0.1)));

echoClient.SetAttribute(“PacketSize”, UintegerValue(512));

ApplicationContainer clientApps = echoClient.Install(clients);

clientApps.Start(Seconds(2.0));

clientApps.Stop(Seconds(10.0));

  1. Simulate Intrusion Attacks
  • Intrusion Scenarios:
    • Eavesdropping: We Seizure their packets among nodes.
    • DoS Attack: Overcome the server through traffic.
    • Packet Injection: Addition the malicious packets into their network.

6.1 Eavesdropping

  • Seizure their packets passing through the attacker node.

void Eavesdrop(Ptr<const Packet> packet) {

NS_LOG_UNCOND(“Captured Packet: ” << *packet);

}

 

Ptr<NetDevice> attackerDevice = attacker.Get(0)->GetDevice(0);

attackerDevice->TraceConnectWithoutContext(“PhyRxEnd”, MakeCallback(&Eavesdrop));

6.2 DoS Attack

  • Transfer a large number of packets to the server.

void DosAttack(Ptr<Node> attacker, Ipv4Address targetAddress, uint16_t port) {

Ptr<Socket> socket = Socket::CreateSocket(attacker, TypeId::LookupByName(“ns3::UdpSocketFactory”));

InetSocketAddress remote = InetSocketAddress(targetAddress, port);

socket->Connect(remote);

for (int i = 0; i < 1000; ++i) {

Simulator::Schedule(MilliSeconds(i), [=]() {

Ptr<Packet> packet = Create<Packet>(1024);  // Example DoS packet

socket->Send(packet);

});

}

}

Simulator::Schedule(Seconds(3.0), &DosAttack, attacker.Get(0), Ipv4Address(“10.1.1.1”), 9);

6.3 Packet Injection

  • Addition the malicious packets into the communication.

void PacketInjection(Ptr<Node> attacker, Ipv4Address targetAddress, uint16_t port) {

Ptr<Socket> socket = Socket::CreateSocket(attacker, TypeId::LookupByName(“ns3::UdpSocketFactory”));

InetSocketAddress remote = InetSocketAddress(targetAddress, port);

socket->Connect(remote);

 

Ptr<Packet> maliciousPacket = Create<Packet>((uint8_t*)”MALICIOUS”, 9);

socket->Send(maliciousPacket);

}

Simulator::Schedule(Seconds(4.0), &PacketInjection, attacker.Get(0), Ipv4Address(“10.1.1.1”), 9);

  1. Enable Packet Tracing
  • Used this PCAP tracing we seizure their packets for examine in Wireshark.

PointToPointHelper p2p;

p2p.EnablePcapAll(“intrusion-attack”);

  1. Run the Simulation
  • We Compile and execute the simulation:

./waf –run intrusion-attack

  • Analyze the generated .pcap files.
  1. Analyse the Attack
  • Open the .pcap files in Wireshark:

wireshark intrusion-attack-0-0.pcap

  • Utilizing their filters we recognize their malicious activity:
    • UDP Flood: udp && ip.dst == <server IP>
    • Injected Packets: Look for custom payloads.
  1. Implement Detection and Mitigation
  • Detection:
    • We observe the packet rates and flag anomalies.
    • Sample:

void MonitorTraffic(Ptr<const Packet> packet) {

static std::map<Ipv4Address, int> packetCounts;

Ipv4Header ipv4Header;

packet->PeekHeader(ipv4Header);

packetCounts[ipv4Header.GetSource()]++;

if (packetCounts[ipv4Header.GetSource()] > 100) {

NS_LOG_UNCOND(“Potential Attack from: ” << ipv4Header.GetSource());

}

}

  • Mitigation:
    • Traffic incoming their rate limits.
    • Filter malicious packets according to content or source IP.
  1. Evaluate Metrics
  • Calculate the attack’s effect:
    • Throughput: The throughput degradation caused by the attack.
    • Packet Delivery Ratio (PDR): The impact of legitimate traffic.
    • Latency: It Delay due to resource exhaustion.
  • Utilized their FlowMonitor for detailed analysis:

FlowMonitorHelper flowmon;

Ptr<FlowMonitor> monitor = flowmon.InstallAll();

  1. Extend the Simulation
  • Testing by multiple attack scenarios such as intensity, techniques.
  • Replicate the mitigation methods such as firewalls or intrusion detection systems (IDS).
