How to Implement Supply Chain Security in OMNeT++
To implement the supply chain security in OMNeT++, has want to mimic a network that denotes numerous stages of a supply chain, joining security mechanisms to defend against potential threats like unauthorized access, data breaches, tampering. Supply chain security in a network context encompasses the integrity, confidentiality, and availability of the data and processes that span across various entities involved in the supply chain.
Step-by-Step Implementations:
- Understand the Components
In a supply chain security simulation, the following components are normally included:
- Supply Chain Entities: These could contain manufacturers, suppliers, distributors, and retailers, each signified as nodes in the network.
- Communication Links: Connections among supply chain entities that facilitate the substitute of information, like shipping details, inventory levels, and orders.
- Security Mechanisms: Firewalls, Intrusion Detection Systems (IDS), and encryption to protected data as it transfers over the supply chain.
- Threat Actors: Nodes that mimic malicious entities attempting to compromise the supply chain by tampering with data, intercepting communication, or getting unauthorized access.
- Define the Network Topology
Describe a network topology in OMNeT++ that signifies the numerous entities in the supply chain and the communication links among them. For instance:
network SupplyChainSecurityNetwork
{
submodules:
manufacturer: SupplyChainNode {
@display(“p=100,200”);
}
supplier: SupplyChainNode {
@display(“p=200,250”);
}
distributor: SupplyChainNode {
@display(“p=300,200”);
}
retailer: SupplyChainNode {
@display(“p=400,250”);
}
attacker: AttackerNode {
@display(“p=500,200”);
}
firewall: FirewallModule {
@display(“p=300,100”);
}
ids: IDSModule {
@display(“p=450,100”);
}
}
connections:
manufacturer.ethg++ <–> Eth100M <–> supplier.ethg++;
supplier.ethg++ <–> Eth100M <–> distributor.ethg++;
distributor.ethg++ <–> Eth100M <–> retailer.ethg++;
retailer.ethg++ <–> Eth100M <–> firewall.ethg++;
firewall.ethg++ <–> Eth100M <–> ids.ethg++;
attacker.ethg++ <–> Eth100M <–> distributor.ethg++;
}
- Implement the Supply Chain Node
Each supply chain entity like manufacturer, supplier, distributor, and retailer will be denoted as a node in the network that connections information with other entities.
Supply Chain Node Implementation
#include <omnetpp.h>
#include “inet/common/INETDefs.h”
#include “inet/applications/udpapp/UDPBasicApp.h”
using namespace omnetpp;
using namespace inet;
class SupplyChainNode : public cSimpleModule
{
protected:
virtual void initialize(int stage) override;
virtual void handleMessage(cMessage *msg) override;
void exchangeData();
};
Define_Module(SupplyChainNode);
void SupplyChainNode::initialize(int stage)
{
cSimpleModule::initialize(stage);
if (stage == inet::INITSTAGE_APPLICATION_LAYER) {
EV << “Supply Chain Node Initialized” << endl;
scheduleAt(simTime() + uniform(1, 3), new cMessage(“exchangeData”));
}
}
void SupplyChainNode::handleMessage(cMessage *msg)
{
if (strcmp(msg->getName(), “exchangeData”) == 0) {
exchangeData();
}
delete msg;
}
void SupplyChainNode::exchangeData()
{
// Simulate exchanging data with other supply chain nodes
Packet *packet = new Packet(“SupplyChainDataPacket”);
packet->insertAtBack(makeShared<Chunk>(std::vector<int>{1, 2, 3})); // Example data
send(packet, “ethgOut”);
// Schedule the next data exchange
scheduleAt(simTime() + uniform(1, 3), new cMessage(“exchangeData”));
}
- Implement the Firewall Module
The Firewall Module filters traffic among supply chain nodes, make sure only legitimate data exchanges happen and blocking any suspicious traffic.
Firewall Module Implementation
#include <omnetpp.h>
#include “inet/common/INETDefs.h”
#include “inet/common/packet/Packet.h”
using namespace omnetpp;
using namespace inet;
class FirewallModule : public cSimpleModule
{
protected:
virtual void initialize() override;
virtual void handleMessage(cMessage *msg) override;
bool isAllowed(Packet *packet);
};
Define_Module(FirewallModule);
void FirewallModule::initialize()
{
EV << “Firewall Module Initialized” << endl;
}
void FirewallModule::handleMessage(cMessage *msg)
{
if (Packet *packet = dynamic_cast<Packet *>(msg)) {
if (isAllowed(packet)) {
send(packet, “ethgOut”);
} else {
EV << “Packet dropped by firewall.” << endl;
delete packet;
}
}
}
bool FirewallModule::isAllowed(Packet *packet)
{
// Implement filtering logic (e.g., block suspicious patterns)
const auto &payload = packet->peekData();
std::string data = payload->str();
return data.find(“malicious”) == std::string::npos; // Example rule
}
- Implement the IDS Module
The IDS Module observes network traffic among supply chain nodes to detect any potential security breaches or unauthorized activities.
IDS Module Implementation
#include <omnetpp.h>
#include “inet/common/INETDefs.h”
#include “inet/common/packet/Packet.h”
using namespace omnetpp;
using namespace inet;
class IDSModule : public cSimpleModule
{
protected:
virtual void initialize() override;
virtual void handleMessage(cMessage *msg) override;
void detectIntrusion(Packet *packet);
};
Define_Module(IDSModule);
void IDSModule::initialize()
{
EV << “IDS Module Initialized” << endl;
}
void IDSModule::handleMessage(cMessage *msg)
{
if (Packet *packet = dynamic_cast<Packet *>(msg)) {
detectIntrusion(packet);
send(packet, “ethgOut”);
}
delete msg;
}
void IDSModule::detectIntrusion(Packet *packet)
{
const auto &payload = packet->peekData();
std::string data = payload->str();
// Implement intrusion detection logic
if (data.find(“malicious”) != std::string::npos) {
EV << “Intrusion detected! Taking action…” << endl;
// Implement any action needed (e.g., alerting, blocking)
}
}
- Implement the Attacker Node
The Attacker Node mimics a threat actor attempting to negotiation the supply chain by tampering with data, intercepting communications, or getting unauthorized access.
Attacker Node Implementation
#include <omnetpp.h>
#include “inet/applications/tcpapp/TcpAppBase.h”
using namespace omnetpp;
using namespace inet;
class AttackerNode : public TcpAppBase
{
protected:
virtual void initialize(int stage) override;
virtual void handleMessageWhenUp(cMessage *msg) override;
void launchSupplyChainAttack();
};
Define_Module(AttackerNode);
void AttackerNode::initialize(int stage)
{
TcpAppBase::initialize(stage);
if (stage == inet::INITSTAGE_APPLICATION_LAYER) {
scheduleAt(simTime() + 2, new cMessage(“launchSupplyChainAttack”));
}
}
void AttackerNode::handleMessageWhenUp(cMessage *msg)
{
if (strcmp(msg->getName(), “launchSupplyChainAttack”) == 0) {
launchSupplyChainAttack();
delete msg;
} else {
TcpAppBase::handleMessageWhenUp(msg);
}
}
void AttackerNode::launchSupplyChainAttack()
{
EV << “Launching attack on the supply chain…” << endl;
// Send a malicious packet to compromise the supply chain
Packet *packet = new Packet(“MaliciousPacket”);
packet->insertAtBack(makeShared<Chunk>(std::vector<int>{999, 999, 999})); // Example malicious data
sendToUDP(packet, localPort, Ipv4AddressResolver().resolve(“distributor”), 5000);
}

}
attacker: AttackerNode {
@display(“p=500,200”);
}
firewall: FirewallModule {
@display(“p=300,100”);
}
ids: IDSModule {
@display(“p=450,100”);
}
}
connections:
manufacturer.ethg++ <–> Eth100M <–> supplier.ethg++;
supplier.ethg++ <–> Eth100M <–> distributor.ethg++;
distributor.ethg++ <–> Eth100M <–> retailer.ethg++;
retailer.ethg++ <–> Eth100M <–> firewall.ethg++;
firewall.ethg++ <–> Eth100M <–> ids.ethg++;
attacker.ethg++ <–> Eth100M <–> distributor.ethg++;
}
- Run the Simulation
Compile and run the simulation in OMNeT++. The network must securely manage data exchange among supply chain entities during detecting and mitigating any attacks or unauthorized activities.
- Analyse the Results
Verify the OMNeT++ simulation log to watch how the network managed data exchanges, detected intrusions, and reacted to attacks. Check that:
- The firewall properly filtered traffic among supply chain nodes.
- The IDS detected any malicious activities or intrusions.
- The attacker node’s activities were mitigated efficiently.
- Extend the Supply Chain Security Simulation
We can expand this setup by:
- Implementing more advanced security mechanisms: Contain approaches like secure multi-party computation, blockchain for supply chain integrity, or advanced encryption techniques.
- Simulating additional threats: Comprise insider threats, supply chain poisoning, or data tampering.
- Adding monitoring and logging: Execute logging mechanisms to trace supply chain activities, incident response actions, and security events.
- Integrating with IoT and cloud environments: Mimic supply chain security in settings with IoT devices or cloud-based supply chain management systems.
