How to Implement Ethical Hacking in OMNeT++

To implement the ethical hacking simulations in OMNeT++ encompasses location in a network atmosphere where changed categories of existences can be replicated, and protective mechanisms can be assessed. To test the security of the network protocols, assess the effectiveness of security measures and understand attack vectors used by this setup.

The given below is to mentioned steps to set up like simulation by using OMNeT++ and the INET Framework.

Step-by-Step Implementations:

Install OMNeT++ and INET Framework

To make sure to have OMNeT++ and the INET Framework installed. To download it from the separate websites and track the installation instructions.

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 like EthicalHackingSimulation.

Import INET into Your Project

Import INET: Right-click on the project in the Project Explorer, handpicked Properties. Go to Project References and squared the INET project.
Copy INET Examples: To the project for reference from the INET framework to copy example configurations.

Define the Network Topology

To express the network topology to together with potential attackers and legitimate nodes to make a fresh NED file.

Example: Ethical Hacking Network Topology (EthicalHackingNetwork.ned)

package ethicalhacking;

import inet.node.inet.StandardHost;

import inet.node.inet.Router;

network EthicalHackingNetwork

{

parameters:

@display(“bgb=800,400”);

submodules:

legitimateHost1: StandardHost {

@display(“p=100,300”);

}

legitimateHost2: StandardHost {

@display(“p=300,300”);

}

attackerHost: StandardHost {

@display(“p=500,300”);

}

server: StandardHost {

@display(“p=700,300”);

}

router: Router {

@display(“p=400,200”);

}

connections:

legitimateHost1.ethg++ <–> Eth10M <–> router.ethg++;

legitimateHost2.ethg++ <–> Eth10M <–> router.ethg++;

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

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

}

In this example:

Expressive by legitimate users to legitimateHost1 and legitimateHost2 are average hosts.
An attacker representing by attackerHost is a average host.
Target server represented by the server is an average host.
Communication among the nodes by router. It is a router facilitating.
The Eth10M channel representations a 10 Mbps Ethernet link.

Configure the Simulation

To build an OMNeT++ initialization file to configure the limits of the simulation.

Example: Configuration File (omnetpp.ini)

[General]

network = ethicalhacking.EthicalHackingNetwork

sim-time-limit = 100s

# Visualization

*.visualizer.canvasVisualizer.displayBackground = true

*.visualizer.canvasVisualizer.displayGrid = true

# Host Configuration

*.legitimateHost*.numApps = 1

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

*.legitimateHost*.app[0].destAddresses = “server”

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

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

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

*.attackerHost.numApps = 1

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

*.attackerHost.app[0].destAddresses = “server”

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

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

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

*.server.numApps = 1

*.server.app[0].typename = “UdpSink”

*.server.app[0].localPort = 5000

# UDP Configuration

*.legitimateHost*.hasUdp = true

*.attackerHost.hasUdp = true

*.server.hasUdp = true

# IP Address Configuration

*.legitimateHost1.ipv4.config = xmldoc(“legitimateHost1.xml”)

*.legitimateHost2.ipv4.config = xmldoc(“legitimateHost2.xml”)

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

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

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

Create IP Address Configuration Files

To make a XML files to state the IP address configuration for every host and the router.

Example: IP Configuration File for legitimateHost1 (legitimateHost1.xml)

</interface>

<route>

</route>

</routing>

</config>

Example: IP Configuration File for legitimateHost2 (legitimateHost2.xml)

</interface>

<route>

</route>

</routing>

</config>

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

</interface>

<route>

</route>

</routing>

</config>

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

</interface>

</config>

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

</interface>

</config>

Implement Ethical Hacking Logic

To act out unlike attacks and defences, must to implement the logic for the attacker and the monitoring/defence mechanisms.

Example: Simple Attack Simulation (Pseudo-Code)

class AttackerApp : public cSimpleModule

{

protected:

virtual void initialize() override;

virtual void handleMessage(cMessage *msg) override;

private:

void launchAttack();

};

void AttackerApp::initialize() {

// Initialization code

scheduleAt(simTime() + 1, new cMessage(“launchAttack”));

}

void AttackerApp::handleMessage(cMessage *msg) {

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

launchAttack();

scheduleAt(simTime() + 1, msg);

} else {

// Handle other messages

}

void AttackerApp::launchAttack() {

// Logic to send malicious packets

}

Example: Simple Defense Mechanism (Pseudo-Code)

class DefenseApp : public cSimpleModule

{

protected:

virtual void initialize() override;

virtual void handleMessage(cMessage *msg) override;

private:

void monitorTraffic();

void blockAttacker();

};

void DefenseApp::initialize() {

// Initialization code

scheduleAt(simTime() + 1, new cMessage(“monitorTraffic”));

}

void DefenseApp::handleMessage(cMessage *msg) {

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

monitorTraffic();

scheduleAt(simTime() + 1, msg);

} else {

// Handle other messages

}

void DefenseApp::monitorTraffic() {

// Logic to monitor network traffic

// If an attack is detected, block the attacker

if (detectAttack()) {

blockAttacker();

}

void DefenseApp::blockAttacker() {

// Logic to block the attacker’s IP address

}

bool DefenseApp::detectAttack() {

// Logic to detect an attack

return false; // Placeholder

}

Run the Simulation

Build the Project: Right-click on the project and pick Build Project.
Run the Simulation: Get on on the green play button in the OMNeT++ IDE to onset the simulation.
