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:
To make sure to have OMNeT++ and the INET Framework installed. To download it from the separate websites and track the installation instructions.
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:
To build an OMNeT++ initialization file to configure the limits of the simulation.
Example: Configuration File (omnetpp.ini)

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)
<config>
<interface>
<name>eth0</name>
<address>192.168.1.1</address>
<netmask>255.255.255.0</netmask>
</interface>
<routing>
<route>

<netmask>0.0.0.0</netmask>
<gateway>192.168.1.254</gateway>

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

<netmask>255.255.255.0</netmask>

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

<address>192.168.1.254</address>
<netmask>255.255.255.0</netmask>

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
}
