How to Start Eavesdropping Attack Projects Using OMNeT++

To create an eavesdropping attack simulation project in OMNeT++ includes the designing the behavior for an attacker node which interrupts and logs network communication among other nodes. This project is related for analysis the security vulnerabilities and mitigation approaches in networks. Below is a step-by-step guide for implementation process:

Steps to Start Eavesdropping Attack Projects Using OMNeT++

  1. Understand Eavesdropping Attacks
  • Definition: Eavesdropping happens after the attacker interrupts communication among two parties deprived of authorization.
  • Simulation Goals:
    • Design the network transmission for susceptible to eavesdropping.
    • Apply the attacker nodes that passively attend for the congestion.
    • Estimate the effect and recognize the mitigation methods.
  1. Set Up the OMNeT++ Environment
  • Install OMNeT++: Download and setting the OMNeT++ from the official website.
  • Install INET Framework:
    • INET has handled the network protocols for sample TCP, UDP, Ethernet needed for this project.
  1. Define the Project Scope

Step 3.1: Attack Scenario

  • Transmission among the two legitimate nodes for sample Client and Server.
  • An attacker node interrupts transmission deprived of modifying the packets.

Step 3.2: Metrics

  • Measure:
    • Number of interrupted for congestion.
    • Potential data are leaked.
    • Performance overhead caused through the attack.
  1. Design Network Topology

State a simple topology through three nodes: a client, a server, and an attacker. The attacker tracks the connection among the client and server.

Example .ned file:

network EavesdroppingNetwork {

submodules:

client: StandardHost;

server: StandardHost;

attacker: StandardHost;  // Passive eavesdropper

router: Router;

connections:

client.ethg++ <–> EthernetLink <–> router.ethg++;

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

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

}

  1. Implement Eavesdropping Behavior

Step 5.1: Modify Attacker Behavior

Build a module we replicate the attacker passively capturing packets:

#include <omnetpp.h>

#include “inet/common/packet/Packet.h”

using namespace omnetpp;

using namespace inet;

class Eavesdropper : public cSimpleModule {

protected:

virtual void initialize() override;

virtual void handleMessage(cMessage *msg) override;

};

Define_Module(Eavesdropper);

void Eavesdropper::initialize() {

EV << “Eavesdropper initialized. Listening to traffic…\n”;

}

void Eavesdropper::handleMessage(cMessage *msg) {

// Log intercepted packets

Packet *packet = check_and_cast<Packet *>(msg);

EV << “Intercepted packet: ” << packet->getName() << “\n”;

// Optionally forward the packet (to remain passive)

send(msg, “out”);

}

Step 5.2: Attach Eavesdropper to the Attacker Node

In the .ned file, connect the eavesdropper’s outcome port we replicate the passive behavior:

attacker.applications[0].typename = “Eavesdropper”;

  1. Simulate Legitimate Traffic

Step 6.1: Configure Client and Server Applications

Use INET’s TcpApp or UdpBasicApp for client-server communication.

Client Configuration:

**.client.numApps = 1

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

**.client.app[0].destAddress = “server”

**.client.app[0].startTime = 1s

**.client.app[0].messageLength = 512B

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

Server Configuration:

**.server.numApps = 1

**.server.app[0].typename = “UdpSink”

  1. Configure Simulation

Enhance the parameters for the attacker and network in the .ini file:

[Config EavesdroppingSimulation]

network = EavesdroppingNetwork

# Attacker configuration

**.attacker.numApps = 1

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

# Network link properties

*.router*.datarate = 100Mbps

*.router*.delay = 1ms

  1. Run the Simulation
  • Start the simulation in the OMNeT++ IDE.
  • Observe:
    • Legitimate transmission among the client and server.
    • Logs are created through the eavesdropper display the interrupted packets.
  1. Analyze Results
  • Estimate the eavesdropper’s success in seizing the data.
  • Metrics to analyze:
    • Number of packets interrupted based on the outcomes.
    • Kinds for interrupted data such as headers, payloads.
  1. Enhance the Project

Step 10.1: Simulate Encryption

  • Launch the encode for protect the transmission:
    • Improve the module to encode the data previously transmitting and decode the receivers.
  • Examine on how the encode mitigates eavesdropping.

Step 10.2: Implement Detection

  • Enhance the intrusion detection mechanisms we classify the eavesdropping behavior:
    • Track the abnormal congestion at the switches/routers.
    • Anomaly detection used for the machine learning.

Step 10.3: Simulate Advanced Eavesdropping

  • Enhance the attacker module to:
    • The congestion are specific the filter for sample packets with specific IPs.
    • Repeat or Alter the interrupted packets such as for active eavesdropping.

Example Output

  • Packet Logs: The attacker logs are the terms and contents for the intercepted packets.
  • Network Impact: Resource utilization is due to the attack or for examines the delays.
