To implement the security incident management in ns3 has needs to include setup the network emulation then the security scenarios were identified, logged and responded to. This is commonly contains various components like incident detection (intrusion detection systems), logging, alerting mechanisms, and automated or manual responses to incidents. The given below are the detailed procedures on how to implement the security incident management in ns3:
Step-by-Step Implementation
Step 1: Set Up the ns3 Environment
Make sure ns3 is installed in the system.
Step 2: Define the Network Topology
Generate a network topology that contains nodes that denotes clients, servers, and possibly an attacker.
#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 (“SecurityIncidentManagementExample”);
int main (int argc, char *argv[]) {
CommandLine cmd;
cmd.Parse (argc, argv);
// Create nodes
NodeContainer clients;
clients.Create (2); // Client nodes
NodeContainer servers;
servers.Create (2); // Server nodes
NodeContainer attackerNode;
attackerNode.Create (1); // Attacker node
// Create point-to-point links
PointToPointHelper pointToPoint;
pointToPoint.SetDeviceAttribute (“DataRate”, StringValue (“10Mbps”));
pointToPoint.SetChannelAttribute (“Delay”, StringValue (“2ms”));
NetDeviceContainer devices;
devices.Add (pointToPoint.Install (NodeContainer (clients.Get (0), servers.Get (0))));
devices.Add (pointToPoint.Install (NodeContainer (clients.Get (1), servers.Get (1))));
devices.Add (pointToPoint.Install (NodeContainer (servers.Get (0), servers.Get (1))));
devices.Add (pointToPoint.Install (NodeContainer (servers.Get (1), attackerNode.Get (0))));
// Install Internet stack
InternetStackHelper stack;
stack.Install (clients);
stack.Install (servers);
stack.Install (attackerNode);
// Assign IP addresses
Ipv4AddressHelper address;
address.SetBase (“10.1.1.0”, “255.255.255.0”);
Ipv4InterfaceContainer interfaces = address.Assign (devices);
// Create and configure applications…
Simulator::Run ();
Simulator::Destroy ();
return 0;
}
Step 3: Simulate Communication
Generate applications to emulate communication among clients and servers.
Client Application:
class ClientApplication : public Application {
public:
ClientApplication () : m_socket (0) {}
virtual ~ClientApplication () {}
protected:
virtual void StartApplication () {
m_socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
InetSocketAddress local = InetSocketAddress (Ipv4Address::GetAny (), 8080);
m_socket->Bind (local);
m_socket->SetRecvCallback (MakeCallback (&ClientApplication::HandleRead, this));
Simulator::Schedule (Seconds (2.0), &ClientApplication::SendData, this);
}
virtual void StopApplication () {
if (m_socket) {
m_socket->Close ();
m_socket = 0;
}
}
private:
void SendData () {
Ptr<Packet> packet = Create<Packet> ((uint8_t*)”client-data”, 11);
m_socket->SendTo (packet, 0, InetSocketAddress (Ipv4Address (“10.1.1.1”), 8080)); // Send to server
Simulator::Schedule (Seconds (5.0), &ClientApplication::SendData, this);
}
void HandleRead (Ptr<Socket> socket) {
Ptr<Packet> packet;
Address from;
while ((packet = socket->RecvFrom (from))) {
NS_LOG_INFO (“Client received: ” << packet->GetSize ());
}
}
Ptr<Socket> m_socket;
};
Server Application:
class ServerApplication : public Application {
public:
ServerApplication () : m_socket (0) {}
virtual ~ServerApplication () {}
protected:
virtual void StartApplication () {
m_socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
InetSocketAddress local = InetSocketAddress (Ipv4Address::GetAny (), 8080);
m_socket->Bind (local);
m_socket->SetRecvCallback (MakeCallback (&ServerApplication::HandleRead, this));
}
virtual void StopApplication () {
if (m_socket) {
m_socket->Close ();
m_socket = 0;
}
}
private:
void HandleRead (Ptr<Socket> socket) {
Ptr<Packet> packet;
Address from;
while ((packet = socket->RecvFrom (from))) {
NS_LOG_INFO (“Server received: ” << packet->GetSize ());
// Process data and respond if necessary
std::string responseData = “processed-data”;
Ptr<Packet> responsePacket = Create<Packet> ((uint8_t*)responseData.c_str (), responseData.size ());
m_socket->SendTo (responsePacket, 0, InetSocketAddress::ConvertFrom (from));
}
}
Ptr<Socket> m_socket;
};
Step 4: Implement Security Incident Management Components
Logging
Create a logging mechanism to log security incidents.
class LoggingApplication : public Application {
public:
LoggingApplication () : m_socket (0) {}
virtual ~LoggingApplication () {}
protected:
virtual void StartApplication () {
m_socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
InetSocketAddress local = InetSocketAddress (Ipv4Address::GetAny (), 9090);
m_socket->Bind (local);
m_socket->SetRecvCallback (MakeCallback (&LoggingApplication::HandleRead, this));
}
virtual void StopApplication () {
if (m_socket) {
m_socket->Close ();
m_socket = 0;
}
}
private:
void HandleRead (Ptr<Socket> socket) {
Ptr<Packet> packet;
Address from;
while ((packet = socket->RecvFrom (from))) {
NS_LOG_INFO (“Log entry: ” << packet->GetSize () << ” bytes from ” << InetSocketAddress::ConvertFrom (from).GetIpv4 ());
}
}
Ptr<Socket> m_socket;
};
Intrusion Detection System (IDS)
Detect and log security incidents.
class IDSApplication : public Application {
public:
IDSApplication () : m_socket (0) {}
virtual ~IDSApplication () {}
protected:
virtual void StartApplication () {
m_socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
InetSocketAddress local = InetSocketAddress (Ipv4Address::GetAny (), 5050);
m_socket->Bind (local);
m_socket->SetRecvCallback (MakeCallback (&IDSApplication::HandleRead, this));
}
virtual void StopApplication () {
if (m_socket) {
m_socket->Close ();
m_socket = 0;
}
}
private:
void HandleRead (Ptr<Socket> socket) {
Ptr<Packet> packet;
Address from;
while ((packet = socket->RecvFrom (from))) {
std::string data = std::string ((char*) packet->PeekData ());
if (DetectIntrusion (data)) {
NS_LOG_WARN (“Intrusion detected from ” << InetSocketAddress::ConvertFrom (from).GetIpv4 ());
LogIncident (data, InetSocketAddress::ConvertFrom (from).GetIpv4 ());
} else {
NS_LOG_INFO (“Normal traffic from ” << InetSocketAddress::ConvertFrom (from).GetIpv4 ());
}
}
}
bool DetectIntrusion (const std::string& data) {
// Simplified intrusion detection logic
return data == “malicious-pattern”;
}
void LogIncident (const std::string& data, Ipv4Address sourceIp) {
Ptr<Socket> logSocket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
InetSocketAddress remote = InetSocketAddress (Ipv4Address (“10.1.1.2”), 9090); // Logging server IP
logSocket->Connect (remote);
std::string logEntry = “Intrusion detected from ” + sourceIp.ToString () + ” with data: ” + data;
Ptr<Packet> logPacket = Create<Packet> ((uint8_t*)logEntry.c_str (), logEntry.size ());
logSocket->Send (logPacket);
logSocket->Close ();
}
Ptr<Socket> m_socket;
};
Response
Create a response mechanism to handle security incidents.
class ResponseApplication : public Application {
public:
ResponseApplication () : m_socket (0) {}
virtual ~ResponseApplication () {}
protected:
virtual void StartApplication () {
m_socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
InetSocketAddress local = InetSocketAddress (Ipv4Address::GetAny (), 6060);
m_socket->Bind (local);
m_socket->SetRecvCallback (MakeCallback (&ResponseApplication::HandleRead, this));
}
virtual void StopApplication () {
if (m_socket) {
m_socket->Close ();
m_socket = 0;
}
}
private:
void HandleRead (Ptr<Socket> socket) {
Ptr<Packet> packet;
Address from;
while ((packet = socket->RecvFrom (from))) {
NS_LOG_INFO (“Response to incident from ” << InetSocketAddress::ConvertFrom (from).GetIpv4 ());
// Perform response action, such as notifying admin or blocking IP
}
}
Ptr<Socket> m_socket;
};
Step 5: Deploy Applications
Instantiate and deploy the applications on the appropriate nodes in your network:
int main (int argc, char *argv[]) {
CommandLine cmd;
cmd.Parse (argc, argv);
// Create nodes
NodeContainer clients;
clients.Create (2); // Client nodes
NodeContainer servers;
servers.Create (2); // Server nodes
NodeContainer attackerNode;
attackerNode.Create (1); // Attacker node
NodeContainer loggingNode;
loggingNode.Create (1); // Logging node
NodeContainer responseNode;
responseNode.Create (1); // Response node
// Create point-to-point links
PointToPointHelper pointToPoint;
pointToPoint.SetDeviceAttribute (“DataRate”, StringValue (“10Mbps”));
pointToPoint.SetChannelAttribute (“Delay”, StringValue (“2ms”));
NetDeviceContainer devices;
devices.Add (pointToPoint.Install (NodeContainer (clients.Get (0), servers.Get (0))));
devices.Add (pointToPoint.Install (NodeContainer (clients.Get (1), servers.Get (1))));
devices.Add (pointToPoint.Install (NodeContainer (servers.Get (0), servers.Get (1))));
devices.Add (pointToPoint.Install (NodeContainer (servers.Get (1), attackerNode.Get (0))));
devices.Add (pointToPoint.Install (NodeContainer (servers.Get (1), loggingNode.Get (0))));
devices.Add (pointToPoint.Install (NodeContainer (loggingNode.Get (0), responseNode.Get (0))));
// Install Internet stack
InternetStackHelper stack;
stack.Install (clients);
stack.Install (servers);
stack.Install (attackerNode);
stack.Install (loggingNode);
stack.Install (responseNode);
// Assign IP addresses
Ipv4AddressHelper address;
address.SetBase (“10.1.1.0”, “255.255.255.0”);
Ipv4InterfaceContainer interfaces = address.Assign (devices);
// Create and configure the Client application
for (uint32_t i = 0; i < clients.GetN (); ++i) {
Ptr<ClientApplication> clientApp = CreateObject<ClientApplication> ();
clients.Get (i)->AddApplication (clientApp);
clientApp->SetStartTime (Seconds (1.0));
clientApp->SetStopTime (Seconds (20.0));
}
// Create and configure the Server application
for (uint32_t i = 0; i < servers.GetN (); ++i) {
Ptr<ServerApplication> serverApp = CreateObject<ServerApplication> ();
servers.Get (i)->AddApplication (serverApp);
serverApp->SetStartTime (Seconds (1.0));
serverApp->SetStopTime (Seconds (20.0));
}
// Create and configure the IDS application
Ptr<IDSApplication> idsApp = CreateObject<IDSApplication> ();
servers.Get (1)->AddApplication (idsApp);
idsApp->SetStartTime (Seconds (1.0));
idsApp->SetStopTime (Seconds (20.0));
// Create and configure the Logging application
Ptr<LoggingApplication> logApp = CreateObject<LoggingApplication> ();
loggingNode.Get (0)->AddApplication (logApp);
logApp->SetStartTime (Seconds (1.0));
logApp->SetStopTime (Seconds (20.0));
// Create and configure the Response application
Ptr<ResponseApplication> responseApp = CreateObject<ResponseApplication> ();
responseNode.Get (0)->AddApplication (responseApp);
responseApp->SetStartTime (Seconds (1.0));
responseApp->SetStopTime (Seconds (20.0));
Simulator::Run ();
Simulator::Destroy ();
return 0;
}
Step 6: Simulate an Attack
To test the security mechanisms, simulate an attack from the attacker node:
class AttackerApplication : public Application {
public:
AttackerApplication () : m_socket (0) {}
virtual ~AttackerApplication () {}
protected:
virtual void StartApplication () {
m_socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
m_peer = InetSocketAddress (Ipv4Address (“10.1.1.1”), 8080); // Target server
m_socket->Connect (m_peer);
Simulator::Schedule (Seconds (3.0), &AttackerApplication::SendMaliciousPacket, this);
}
virtual void StopApplication () {
if (m_socket) {
m_socket->Close ();
m_socket = 0;
}
}
private:
void SendMaliciousPacket () {
std::string maliciousData = “malicious-pattern”; // Simplified malicious pattern
Ptr<Packet> packet = Create<Packet> ((uint8_t*)maliciousData.c_str (), maliciousData.size ());
m_socket->Send (packet);
}
Ptr<Socket> m_socket;
Address m_peer;
};
int main (int argc, char *argv[]) {
CommandLine cmd;
cmd.Parse (argc, argv);
// Create nodes
NodeContainer clients;
clients.Create (2); // Client nodes
NodeContainer servers;
servers.Create (2); // Server nodes
NodeContainer attackerNode;
attackerNode.Create (1); // Attacker node
NodeContainer loggingNode;
loggingNode.Create (1); // Logging node
NodeContainer responseNode;
responseNode.Create (1); // Response node
// Create point-to-point links
PointToPointHelper pointToPoint;
pointToPoint.SetDeviceAttribute (“DataRate”, StringValue (“10Mbps”));
pointToPoint.SetChannelAttribute (“Delay”, StringValue (“2ms”));
NetDeviceContainer devices;
devices.Add (pointToPoint.Install (NodeContainer (clients.Get (0), servers.Get (0))));
devices.Add (pointToPoint.Install (NodeContainer (clients.Get (1), servers.Get (1))));
devices.Add (pointToPoint.Install (NodeContainer (servers.Get (0), servers.Get (1))));
devices.Add (pointToPoint.Install (NodeContainer (servers.Get (1), attackerNode.Get (0))));
devices.Add (pointToPoint.Install (NodeContainer (servers.Get (1), loggingNode.Get (0))));
devices.Add (pointToPoint.Install (NodeContainer (loggingNode.Get (0), responseNode.Get (0))));
// Install Internet stack
InternetStackHelper stack;
stack.Install (clients);
stack.Install (servers);
stack.Install (attackerNode);
stack.Install (loggingNode);
stack.Install (responseNode);
// Assign IP addresses
Ipv4AddressHelper address;
address.SetBase (“10.1.1.0”, “255.255.255.0”);
Ipv4InterfaceContainer interfaces = address.Assign (devices);
// Create and configure the Client application
for (uint32_t i = 0; i < clients.GetN (); ++i) {
Ptr<ClientApplication> clientApp = CreateObject<ClientApplication> ();
clients.Get (i)->AddApplication (clientApp);
clientApp->SetStartTime (Seconds (1.0));
clientApp->SetStopTime (Seconds (20.0));
}
// Create and configure the Server application
for (uint32_t i = 0; i < servers.GetN (); ++i) {
Ptr<ServerApplication> serverApp = CreateObject<ServerApplication> ();
servers.Get (i)->AddApplication (serverApp);
serverApp->SetStartTime (Seconds (1.0));
serverApp->SetStopTime (Seconds (20.0));
}
// Create and configure the IDS application
Ptr<IDSApplication> idsApp = CreateObject<IDSApplication> ();
servers.Get (1)->AddApplication (idsApp);
idsApp->SetStartTime (Seconds (1.0));
idsApp->SetStopTime (Seconds (20.0));
// Create and configure the Logging application
Ptr<LoggingApplication> logApp = CreateObject<LoggingApplication> ();
loggingNode.Get (0)->AddApplication (logApp);
logApp->SetStartTime (Seconds (1.0));
logApp->SetStopTime (Seconds (20.0));
// Create and configure the Response application
Ptr<ResponseApplication> responseApp = CreateObject<ResponseApplication> ();
responseNode.Get (0)->AddApplication (responseApp);
responseApp->SetStartTime (Seconds (1.0));
responseApp->SetStopTime (Seconds (20.0));
// Create and configure the Attacker application
Ptr<AttackerApplication> attackerApp = CreateObject<AttackerApplication> ();
attackerNode.Get (0)->AddApplication (attackerApp);
attackerApp->SetStartTime (Seconds (3.0));
attackerApp->SetStopTime (Seconds (4.0));
Simulator::Run ();
Simulator::Destroy ();
return 0;
}
Here, we had understood how to secure the communication in the security incident network that were implemented by using ns3 implementation tool and also we plan to provide the additional details regarding the security incident management. To help you set up network Security Incident Management in the ns3 program, we’re here to offer some guidance and a quick overview. If you share your project details with us, we can provide even more support.
