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);

}

Integrate All Components into the Supply Chain Security Simulation

Incorporate the supply firewall, IDS, chain nodes, and attacker node into the network to make a complete supply chain security simulation.

@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++;

}

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.
