How to Implement Cybersecurity in OMNeT++

To implement the cybersecurity in OMNeT++, we have to analyze different security mechanisms, detect vulnerabilities and examine the effect of attacks by simulating a network which has security features. We can use INET framework tools which will help with simulating various point of view of network security. Here’s a step-by-step guide to implementing cybersecurity in OMNeT++ using the INET framework:

Step-by-Step Implementation:

Install OMNeT++ and INET Framework

Make sure to install both the OMNeT++ and the INET Framework.

Create a New OMNeT++ Project

Open OMNeT++ IDE: Start the OMNeT++ IDE.
Create a New Project: Go to File -> New -> OMNeT++ Project. Name your project (for instance: CyberSecuritySimulation).

Define the Network Topology

Create a new NED file to define the network topology, including hosts, switches/routers, and any distinct security devices.

Example: Cybersecurity Network Topology (CyberSecurityNetwork.ned)

package cybersecurity;

import inet.node.inet.StandardHost;

import inet.node.inet.Router;

network CyberSecurityNetwork

{

parameters:

@display(“bgb=800,400”);

submodules:

host1: StandardHost {

@display(“p=100,200”);

}

host2: StandardHost {

@display(“p=300,200”);

}

router: Router {

@display(“p=200,100”);

}

attacker: StandardHost {

@display(“p=100,50”);

}

connections allowunconnected:

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

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

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

}

Configure the Simulation

Create an initialization file of OMNeT++ to configure the simulation’s parameters.

Example: Configuration File (omnetpp.ini)

[General]

network = cybersecurity.CyberSecurityNetwork

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

# Attacker Configuration

*.attacker.numApps = 1

*.attacker.app[0].typename = “AttackerApp”

*.attacker.app[0].destAddresses = “host1”

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

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

*.attacker.app[0].sendInterval = 0.1s

# IP Address Configuration

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

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

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

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

Create IP Address Configuration Files

Create XML files to define the IP address configuration for all nodes.

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>

</config>

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

</interface>

</config>

Implement Security and Attack Logic

Execute the custom applications especially for hosts and the attacker by simulating the security mechanisms and attacks.

Example: Attacker Application (Pseudo-Code)

#include <omnetpp.h>

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

using namespace omnetpp;

using namespace inet;

class AttackerApp : public UdpBasicApp

{

protected:

virtual void initialize(int stage) override;

virtual void handleMessageWhenUp(cMessage *msg) override;

};

Define_Module(AttackerApp);

void AttackerApp::initialize(int stage) {

UdpBasicApp::initialize(stage);

if (stage == INITSTAGE_APPLICATION_LAYER) {

// Custom initialization code

}

void AttackerApp::handleMessageWhenUp(cMessage *msg) {

UdpBasicApp::handleMessageWhenUp(msg);

// Custom message handling code, e.g., sending malicious packets

}

Example: Host Application with Intrusion Detection System (IDS) Logic (Pseudo-Code)

#include <omnetpp.h>

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

using namespace omnetpp;

using namespace inet;

class HostAppWithIDS : public UdpBasicApp

{

protected:

virtual void initialize(int stage) override;

virtual void handleMessageWhenUp(cMessage *msg) override;

void detectIntrusion(cMessage *msg);

};

Define_Module(HostAppWithIDS);

void HostAppWithIDS::initialize(int stage) {

UdpBasicApp::initialize(stage);

if (stage == INITSTAGE_APPLICATION_LAYER) {

// Custom initialization code

}

void HostAppWithIDS::handleMessageWhenUp(cMessage *msg) {

// Custom message handling code

detectIntrusion(msg);

UdpBasicApp::handleMessageWhenUp(msg);

}

void HostAppWithIDS::detectIntrusion(cMessage *msg) {

// Logic to detect intrusion based on the received message

// Example: if the message frequency is too high, detect an intrusion

}

Run the Simulation

Build the Project: Right-click on project and select Build Project.
Run the Simulation: Click on the green play button in the OMNeT++ IDE to start the simulation.
