To implement the network multi-attacks detection in ns3 solely depends on the behaviors it has to detect different kind of attacks by creating the mechanisms.
Provided guide will show you how to set up a simple network, simulate different types of attacks, and implement a multi-attacks detection system in ns3.
Step-by-Step Implementation:
Step 1: Set Up ns3 Environment
- Install ns3: Make sure to install the ns3. Follow the installation guide suitable for your operating system.
- Familiarize Yourself with ns3: Tutorial will help to know about the ns3’basic concepts and its simulation structure.
Step 2: Define the Network Topology
- Create a Simple Network: We can use ns3 to describe a basic network topology that involves creating nodes, setting up channels, and configuring IP addresses.
#include “ns3/core-module.h”
#include “ns3/network-module.h”
#include “ns3/internet-module.h”
#include “ns3/point-to-point-module.h”
using namespace ns3;
int main(int argc, char *argv[]) {
NodeContainer nodes;
nodes.Create(4); // Example: 4 nodes (1 server, 2 clients, 1 potential attacker)
PointToPointHelper pointToPoint;
pointToPoint.SetDeviceAttribute(“DataRate”, StringValue(“5Mbps”));
pointToPoint.SetChannelAttribute(“Delay”, StringValue(“2ms”));
NetDeviceContainer devices;
devices = pointToPoint.Install(nodes);
InternetStackHelper stack;
stack.Install(nodes);
Ipv4AddressHelper address;
address.SetBase(“10.1.1.0”, “255.255.255.0”);
Ipv4InterfaceContainer interfaces = address.Assign(devices);
Simulator::Run();
Simulator::Destroy();
return 0;
}
Step 3: Implement Multi-Attacks Detection Mechanism
- Create Multi-Attacks Detection Application: As per the given criteria or statistical analysis it has to monitor the network traffic and detect the various types of attacks by developing the application or module.
class MultiAttacksDetectionApp : public Application {
public:
MultiAttacksDetectionApp() {}
virtual ~MultiAttacksDetectionApp() {}
void SetDetectionCriteria(std::function<void(Ptr<const Packet>, Ptr<Ipv4> ipv4)> criteria) {
m_criteria = criteria;
}
private:
virtual void StartApplication() {
// Schedule the first packet inspection
Simulator::Schedule(Seconds(1.0), &MultiAttacksDetectionApp::InspectTraffic, this);
}
virtual void StopApplication() {
// Teardown code
}
void InspectTraffic() {
Ptr<Ipv4> ipv4 = GetNode()->GetObject<Ipv4>();
for (uint32_t i = 0; i < ipv4->GetNInterfaces(); ++i) {
for (uint32_t j = 0; j < ipv4->GetNAddresses(i); ++j) {
Ipv4InterfaceAddress addr = ipv4->GetAddress(i, j);
Ptr<Packet> packet = Create<Packet>(1024); // Example packet inspection
m_criteria(packet, ipv4);
}
}
// Reschedule the next inspection
Simulator::Schedule(Seconds(1.0), &MultiAttacksDetectionApp::InspectTraffic, this);
}
std::function<void(Ptr<const Packet>, Ptr<Ipv4> ipv4)> m_criteria;
};
Integrate Multi-Attacks Detection Logic: Define the logic for spotting several types of attacks. This could involve analyzing traffic patterns, packet sizes, or other criteria.
Ptr<MultiAttacksDetectionApp> detectionApp = CreateObject<MultiAttacksDetectionApp>();
detectionApp->SetDetectionCriteria([](Ptr<const Packet> packet, Ptr<Ipv4> ipv4) {
// Define detection logic for multiple attacks
Ipv4Header ipv4Header;
packet->PeekHeader(ipv4Header);
Ipv4Address srcAddress = ipv4Header.GetSource();
// Example criteria for detecting different types of attacks
if (srcAddress == Ipv4Address(“10.1.1.3”)) {
// Detected a potential DoS attack from node 3
std::cout << “Detected DoS attack from ” << srcAddress << std::endl;
} else if (packet->GetSize() > 1500) {
// Detected a potential data exfiltration attack
std::cout << “Detected data exfiltration attack” << std::endl;
} else if (srcAddress == Ipv4Address(“10.1.1.2”)) {
// Detected a potential scanning attack from node 2
std::cout << “Detected scanning attack from ” << srcAddress << std::endl;
}
});
Ptr<Node> serverNode = nodes.Get(0); // Example: Server node
serverNode->AddApplication(detectionApp);
Step 4: Simulate Different Types of Attacks
- Create DoS Attack Simulation: Cultivate an application that simulates a Denial of Service (DoS) attack.
class DoSAttackApp : public Application {
public:
DoSAttackApp() {}
virtual ~DoSAttackApp() {}
private:
virtual void StartApplication() {
// Schedule the first attack activity
Simulator::Schedule(Seconds(1.0), &DoSAttackApp::LaunchAttack, this);
}
virtual void StopApplication() {
// Teardown code
}
void LaunchAttack() {
Ptr<Packet> packet = Create<Packet>(1024); // Example DoS packet
// Simulate DoS attack (e.g., send packets to the server node)
// Reschedule attack activity
Simulator::Schedule(Seconds(0.1), &DoSAttackApp::LaunchAttack, this);
}
};
Ptr<DoSAttackApp> dosAttackApp = CreateObject<DoSAttackApp>();
Ptr<Node> attackerNode1 = nodes.Get(3); // Example: Attacker node
attackerNode1->AddApplication(dosAttackApp);
dosAttackApp->SetStartTime(Seconds(2.0));
dosAttackApp->SetStopTime(Seconds(10.0));
Create Data Exfiltration Simulation: Simulate the data exfiltration behavior by building an application.
class DataExfiltrationApp : public Application {
public:
DataExfiltrationApp() {}
virtual ~DataExfiltrationApp() {}
private:
virtual void StartApplication() {
// Schedule the first exfiltration activity
Simulator::Schedule(Seconds(1.0), &DataExfiltrationApp::ExfiltrateData, this);
}
virtual void StopApplication() {
// Teardown code
}
void ExfiltrateData() {
Ptr<Packet> packet = Create<Packet>(2048); // Example exfiltration packet
// Simulate data exfiltration (e.g., send large packet to external server)
// Reschedule exfiltration activity
Simulator::Schedule(Seconds(0.5), &DataExfiltrationApp::ExfiltrateData, this);
}
};
Ptr<DataExfiltrationApp> exfiltrationApp = CreateObject<DataExfiltrationApp>();
Ptr<Node> attackerNode2 = nodes.Get(2); // Example: Attacker node
attackerNode2->AddApplication(exfiltrationApp);
exfiltrationApp->SetStartTime(Seconds(2.0));
exfiltrationApp->SetStopTime(Seconds(10.0));
Create Scanning Attack Simulation: Build an application that simulates attack caused by network scanning.
class ScanningAttackApp : public Application {
public:
ScanningAttackApp() {}
virtual ~ScanningAttackApp() {}
private:
virtual void StartApplication() {
// Schedule the first scanning activity
Simulator::Schedule(Seconds(1.0), &ScanningAttackApp::ScanNetwork, this);
}
virtual void StopApplication() {
// Teardown code
}
void ScanNetwork() {
Ptr<Packet> packet = Create<Packet>(512); // Example scanning packet
// Simulate network scanning (e.g., send packets to different addresses)
// Reschedule scanning activity
Simulator::Schedule(Seconds(0.2), &ScanningAttackApp::ScanNetwork, this);
}
};
Ptr<ScanningAttackApp> scanningApp = CreateObject<ScanningAttackApp>();
Ptr<Node> attackerNode3 = nodes.Get(1); // Example: Attacker node
attackerNode3->AddApplication(scanningApp);
scanningApp->SetStartTime(Seconds(2.0));
scanningApp->SetStopTime(Seconds(10.0));
Step 5: Run the Simulation and Analyze Results
- Run the Simulation: Run the simulation to observe the behavior of the multi-attacks detection mechanism and the effect of different types of attacks.
detectionApp->SetStartTime(Seconds(2.0));
detectionApp->SetStopTime(Seconds(10.0));
Simulator::Run();
Simulator::Destroy();
Collect Metrics: Aggregate related metrics to determine the performance of multi-attacks detection system like the number of detected attacks, false positives, and false negatives.
Visualize Results: Using Gnuplot or Python’s Matplotlib helps us to visualize the simulation results and analyze the efficiency of your multi-attacks detection mechanism.
