Implementing cyber warfare in ns3 encompasses simulating several attack scenarios, like Distributed Denial of Service (DDoS), malware propagation, and network infiltration, to reading their influence and to build moderation strategies. Now we show a step-by-step approach to execute the cyber warfare scenarios in ns3:
Step-by-Step Implementations:
- Setup ns3 Environment
To make sure to have ns3 installed and configured.
- Define the Network Topology
It embraces several nodes expressive the attackers and the target network for create a network topology. Routers, switches, servers, and client machines are comprises the network topology.
#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;
int main(int argc, char *argv[]) {
NodeContainer nodes;
nodes.Create(6); // 3 for victim network, 1 for router, 2 for attackers
PointToPointHelper pointToPoint;
pointToPoint.SetDeviceAttribute(“DataRate”, StringValue(“5Mbps”));
pointToPoint.SetChannelAttribute(“Delay”, StringValue(“2ms”));
NetDeviceContainer devices;
devices = pointToPoint.Install(nodes.Get(0), nodes.Get(1));
devices.Add(pointToPoint.Install(nodes.Get(1), nodes.Get(2)));
devices.Add(pointToPoint.Install(nodes.Get(1), nodes.Get(3)));
devices.Add(pointToPoint.Install(nodes.Get(1), nodes.Get(4)));
devices.Add(pointToPoint.Install(nodes.Get(4), nodes.Get(5)));
InternetStackHelper stack;
stack.Install(nodes);
Ipv4AddressHelper address;
address.SetBase(“10.1.1.0”, “255.255.255.0”);
Ipv4InterfaceContainer interfaces = address.Assign(devices);
// Other network setup code
Simulator::Run();
Simulator::Destroy();
return 0;
}
- Implement the Attacker Nodes
To simulate different attack behaviours to make a nodes. From multiple attacker nodes as a DDoS attack can be made-up by submerging the network with packets.
class DDoSApp : public Application {
public:
DDoSApp() {}
virtual ~DDoSApp() {}
void Setup(Ptr<Socket> socket, Address address, uint32_t packetSize, uint32_t nPackets, DataRate dataRate) {
m_socket = socket;
m_peer = address;
m_packetSize = packetSize;
m_nPackets = nPackets;
m_dataRate = dataRate;
}
private:
virtual void StartApplication(void) {
m_socket->Bind();
m_socket->Connect(m_peer);
SendPacket();
}
virtual void StopApplication(void) {
m_socket->Close();
}
void SendPacket(void) {
Ptr<Packet> packet = Create<Packet>(m_packetSize);
m_socket->Send(packet);
if (++m_packetsSent < m_nPackets) {
ScheduleTx();
}
}
void ScheduleTx(void) {
Time tNext(Seconds(m_packetSize * 8 / static_cast<double>(m_dataRate.GetBitRate())));
m_sendEvent = Simulator::Schedule(tNext, &DDoSApp::SendPacket, this);
}
Ptr<Socket> m_socket;
Address m_peer;
uint32_t m_packetSize;
uint32_t m_nPackets;
DataRate m_dataRate;
EventId m_sendEvent;
uint32_t m_packetsSent;
};
Ptr<Socket> ns3TcpSocket1 = Socket::CreateSocket(nodes.Get(3), TcpSocketFactory::GetTypeId());
Ptr<Socket> ns3TcpSocket2 = Socket::CreateSocket(nodes.Get(5), TcpSocketFactory::GetTypeId());
Ptr<DDoSApp> ddosApp1 = CreateObject<DDoSApp>();
Ptr<DDoSApp> ddosApp2 = CreateObject<DDoSApp>();
ddosApp1->Setup(ns3TcpSocket1, InetSocketAddress(interfaces.GetAddress(1), 9), 1040, 1000, DataRate(“1Mbps”));
ddosApp2->Setup(ns3TcpSocket2, InetSocketAddress(interfaces.GetAddress(1), 9), 1040, 1000, DataRate(“1Mbps”));
nodes.Get(3)->AddApplication(ddosApp1);
nodes.Get(5)->AddApplication(ddosApp2);
ddosApp1->SetStartTime(Seconds(1.0));
ddosApp1->SetStopTime(Seconds(10.0));
ddosApp2->SetStartTime(Seconds(1.0));
ddosApp2->SetStopTime(Seconds(10.0));
- Monitor and Analyze Traffic
To display and analyse network traffic by using ns3’s tracing capability. This may support to appreciate the control of the cyber warfare activities.
AsciiTraceHelper ascii;
pointToPoint.EnableAsciiAll(ascii.CreateFileStream(“cyber-warfare.tr”));
pointToPoint.EnablePcapAll(“cyber-warfare”);
Ptr<FlowMonitor> flowMonitor;
FlowMonitorHelper flowHelper;
flowMonitor = flowHelper.InstallAll();
- Implement Defensive Measures
Now we measuring to simulate defensive like firewalls or intrusion detection systems (IDS) to evaluate their usefulness beside the attacks.
class IDSApp : public Application {
public:
IDSApp() {}
virtual ~IDSApp() {}
void Setup(Ptr<Socket> socket) {
m_socket = socket;
}
private:
virtual void StartApplication(void) {
m_socket->Bind();
m_socket->Listen();
m_socket->SetRecvCallback(MakeCallback(&IDSApp::HandleRead, this));
}
virtual void StopApplication(void) {
m_socket->Close();
}
void HandleRead(Ptr<Socket> socket) {
Ptr<Packet> packet;
Address from;
while ((packet = socket->RecvFrom(from))) {
// Analyze packet for malicious activity
// Implement detection logic
}
}
Ptr<Socket> m_socket;
};
Ptr<Socket> idsSocket = Socket::CreateSocket(nodes.Get(1), TcpSocketFactory::GetTypeId());
Ptr<IDSApp> idsApp = CreateObject<IDSApp>();
idsApp->Setup(idsSocket);
nodes.Get(1)->AddApplication(idsApp);
idsApp->SetStartTime(Seconds(0.0));
idsApp->SetStopTime(Seconds(20.0));
- Run the Simulation
To observe the performance and impression of the simulated cyber warfare when to accumulate and run the simulation.
./waf configure
./waf build
./waf –run your-simulation-script
- Analyze Results
The impact of the cyber warfare activities to post-process the generated trace and pcap files to examine. For pcap, by using the tools like Wireshark and for traffic analysis, we using ns3’s flow monitor.
Over all the upstairs messages are describe in the way that to achieve the Cyber Warfare in ns3. In this, we know how to implement the Cyber Warfare in ns3 and their steps. We are suggest the ample facts and concepts just about the Cyber Warfare in ns3.
