How to Implement Cyber Law in OMNeT++

To implement the cyber law in OMNeT++, inside the network we have to enforce the rules and regulations by simulating it to make sure security, privacy, and compliance with legal standards. Using modeling network policies, monitoring and response mechanisms that reflect legal requirements, we can simulate the effects of cyber laws because OMNeT++ does not have in-built support for legal frameworks.

However, OMNeT++ is primarily a network simulator. Here’s a step-by-step approach to help you to get started:

Step-by-Step Implementation:

Install OMNeT++ and INET Framework

Make certain, you have OMNeT++ and the INET Framework installed.

Create a New OMNeT++ Project

Open OMNeT++ IDE: Start the OMNeT++ IDE.
Create a New Project: Go to File -> New -> OMNeT++ Project. Name the project (e.g., CyberLawSimulation).

Define the Network Topology

State the network topology that has hosts, routers, and a monitoring and enforcement node by creating a new NED file.

Example: Cyber Law Network Topology (CyberLawNetwork.ned)

package cyberlaw;

import inet.node.inet.StandardHost;

import inet.node.inet.Router;

network CyberLawNetwork

{

parameters:

@display(“bgb=800,400”);

submodules:

host1: StandardHost {

@display(“p=100,200”);

}

host2: StandardHost {

@display(“p=300,200”);

}

router: Router {

@display(“p=200,100”);

}

monitoring: StandardHost {

@display(“p=200,300”);

}

connections allowunconnected:

host1.ethg++ <–> Eth10M <–> router.ethg++;

host2.ethg++ <–> Eth10M <–> router.ethg++;

monitoring.ethg++ <–> Eth10M <–> router.ethg++;

}

Configure the Simulation

Configure the parameters of the simulation by generating initialization file of OMNeT++.

Example: Configuration File (omnetpp.ini)

[General]

network = cyberlaw.CyberLawNetwork

sim-time-limit = 200s

# Visualization

*.visualizer.canvasVisualizer.displayBackground = true

*.visualizer.canvasVisualizer.displayGrid = true

# Host Configuration

*.host*.numApps = 1

*.host*.app[0].typename = “UdpBasicApp”

*.host*.app[0].destAddresses = “host2”

*.host*.app[0].destPort = 5000

*.host*.app[0].messageLength = 1024B

*.host*.app[0].sendInterval = 1s

# Monitoring and Enforcement Node Configuration

*.monitoring.numApps = 1

*.monitoring.app[0].typename = “CyberLawApp”

# IP Address Configuration

*.host1.ipv4.config = xmldoc(“host1.xml”)

*.host2.ipv4.config = xmldoc(“host2.xml”)

*.router.ipv4.config = xmldoc(“router.xml”)

*.monitoring.ipv4.config = xmldoc(“monitoring.xml”)

Create IP Address Configuration Files

Allocate the IP address configuration for each node by making XML files.

Example: IP Configuration File for host1 (host1.xml)

</interface>

</config>

Example: IP Configuration File for host2 (host2.xml)

</interface>

</config>

Example: IP Configuration File for router (router.xml)

</interface>

</interface>

</config>

Example: IP Configuration File for monitoring (monitoring.xml)

</interface>

</config>

Implement Cyber Law Logic

Execute an application that monitor network traffic, verify the policy violations, and takes proper actions by simulating cyber law enforcement.

Example: Cyber Law Application (Pseudo-Code)

#include <omnetpp.h>

#include <inet/applications/udpapp/UdpBasicApp.h>

#include <fstream>

#include <unordered_set>

using namespace omnetpp;

using namespace inet;

class CyberLawApp : public UdpBasicApp

{

protected:

std::ofstream logFile;

std::unordered_set<std::string> blockedIPs;

int maxPacketSize;

virtual void initialize(int stage) override;

virtual void handleMessageWhenUp(cMessage *msg) override;

void monitorTraffic(cMessage *msg);

void logIncident(const std::string &incident);

void enforcePolicy(cMessage *msg);

};

Define_Module(CyberLawApp);

void CyberLawApp::initialize(int stage) {

UdpBasicApp::initialize(stage);

if (stage == INITSTAGE_APPLICATION_LAYER) {

logFile.open(“cyberlaw_log.txt”);

maxPacketSize = 1024; // Example policy: max packet size

}

void CyberLawApp::handleMessageWhenUp(cMessage *msg) {

monitorTraffic(msg);

enforcePolicy(msg);

if (blockedIPs.find(msg->getSenderModule()->getFullPath()) == blockedIPs.end()) {

UdpBasicApp::handleMessageWhenUp(msg);

} else {

// Drop the packet if the sender IP is blocked

delete msg;

}

void CyberLawApp::monitorTraffic(cMessage *msg) {

// Monitor traffic and detect policy violations

if (strcmp(msg->getName(), “udpPacket”) == 0) {

if (msg->getByteLength() > maxPacketSize) {

logIncident(“Policy violation: Packet size exceeds limit”);

enforcePolicy(msg);

}

void CyberLawApp::logIncident(const std::string &incident) {

// Log the incident details to a file

logFile << incident << ” at ” << simTime() << “\n”;

}

void CyberLawApp::enforcePolicy(cMessage *msg) {

// Implement policy enforcement logic

// Example: block the sender IP or drop the packet

blockedIPs.insert(msg->getSenderModule()->getFullPath());

delete msg; // Example: drop the packet

}

Implement Logging and Analysis on Hosts

Hosts can also log precise events and send logs to the monitoring node.

Example: Host Application with Logging (Pseudo-Code)

#include <omnetpp.h>

#include <inet/applications/udpapp/UdpBasicApp.h>

#include <fstream>

using namespace omnetpp;

using namespace inet;

class LoggingHostApp : public UdpBasicApp

{

protected:

std::ofstream logFile;

virtual void initialize(int stage) override;

virtual void handleMessageWhenUp(cMessage *msg) override;

void logEvent(const std::string &event);

};

Define_Module(LoggingHostApp);

void LoggingHostApp::initialize(int stage) {

UdpBasicApp::initialize(stage);

if (stage == INITSTAGE_APPLICATION_LAYER) {

logFile.open(“host_log.txt”);

}

void LoggingHostApp::handleMessageWhenUp(cMessage *msg) {

// Log specific events

logEvent(“Sending packet: ” + std::string(msg->getName()));

UdpBasicApp::handleMessageWhenUp(msg);

}

void LoggingHostApp::logEvent(const std::string &event) {

// Log the event details to a file

logFile << event << ” at ” << simTime() << “\n”;

}

Run the Simulation

Build the Project: Right-click on project and pick Build Project.
Run the Simulation: Start the simulation by clicking on the green play button in the OMNeT++ IDE.
