How to Start Intrusion Attacks Projects Using OMNeT++

To stimulate an Intrusion Attack project in OMNeT++ has includes the replicating for malicious activities in the network and examines the system’s response. Intrusions attacks can be aim at the network layers, exploit vulnerabilities, or disrupt services, create a relevant topic for intrusion detection and prevention system (IDS/IPS) research.

Here’s a step-by-step guide to create an Intrusion Attack Simulation using OMNeT++:

Steps to Start Intrusion Attacks Projects Using OMNeT++

  1. Understand Intrusion Attacks
  • Types of Intrusion Attacks:
    1. DoS/DDoS Attacks: The attack is overloading the system or network by congestion.
    2. MITM (Man-in-the-Middle): Interrupting and modify the communications for MITM.
    3. Spoofing Attacks: Imitating the legitimate node for spoof attacks.
    4. Data Exfiltration: Unauthorized access in transfer the data for exfiltration.
    5. Eavesdropping: Passive interception for packets in the eavesdropping.
  • Objective:
    • Intrusion environment for replicate the network.
    • Estimate the effect for network performance.
    • Optionally, validate the intrusion detection or prevention approaches.
  1. Set Up OMNeT++ and INET Framework
  • Install OMNeT++: Download and set up OMNeT++ from the official website.
  • Install INET Framework:
    • INET delivers help for the general protocols and intrusion scenarios, has involves the TCP, UDP, and IP.
  1. Define Project Scope

Step 3.1: Choose the Intrusion Scenario

  • Examples:
    • Packet Injection: Attacker injects the malicious packets.
    • Traffic Overload: Replicates the DoS attack for a congestion overload.
    • Data Tampering: The tampering modifies the legitimate communication.
    • Unauthorized Access: Bypassing the network security for unauthorized access.

Step 3.2: Metrics

  • Measure:
    • Latency and throughput.
    • Detection rate if IDS is implemented.
    • Packet delivery ratio.
  1. Design Network Topology

Describe a basic topology by legitimate nodes, an attacker node, and observe the node (for IDS/IPS).

Example .ned File:

network IntrusionAttackNetwork {

submodules:

attacker: StandardHost;       // Intrusion node

client: StandardHost;         // Legitimate client

server: StandardHost;         // Target server

monitor: StandardHost;        // IDS/IPS node

router: Router;               // Router connecting all nodes

connections allowunconnected:

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

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

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

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

}

  1. Implement the Intrusion Attack

Step 5.1: Create an Intrusion Module

Write a alter module we replicate an attacker generating malicious traffic.

Example Code: Packet Injection Attack

#include <omnetpp.h>

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

using namespace omnetpp;

using namespace inet;

class IntrusionAttacker : public cSimpleModule {

protected:

virtual void initialize() override;

virtual void handleMessage(cMessage *msg) override;

void sendMaliciousPacket();

};

Define_Module(IntrusionAttacker);

void IntrusionAttacker::initialize() {

// Schedule the first malicious packet

scheduleAt(simTime() + uniform(0.1, 0.2), new cMessage(“sendMalicious”));

}

void IntrusionAttacker::handleMessage(cMessage *msg) {

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

sendMaliciousPacket();

// Repeat attack every 0.05 seconds

scheduleAt(simTime() + 0.05, msg);

}

}

void IntrusionAttacker::sendMaliciousPacket() {

auto pkt = new Packet(“MaliciousPacket”);

pkt->addTag<MacAddressReq>()->setDestAddress(MacAddress::BROADCAST_ADDRESS); // Broadcast malicious traffic

send(pkt, “out”);

EV << “Malicious packet sent to the network.\n”;

}

Step 5.2: IDS/IPS Module (Optional)

  • Enhance the track node we find and log malicious activity.

Example IDS Module:

class IntrusionDetector : public cSimpleModule {

protected:

virtual void handleMessage(cMessage *msg) override;

};

Define_Module(IntrusionDetector);

void IntrusionDetector::handleMessage(cMessage *msg) {

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

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

// Simple rule-based detection (e.g., detect “MaliciousPacket”)

if (strcmp(pkt->getName(), “MaliciousPacket”) == 0) {

EV << “Intrusion detected: ” << pkt->getName() << “\n”;

}

delete pkt;

}

  1. Configure the Simulation

Example .ini File Configuration:

[Config IntrusionSimulation]

network = IntrusionAttackNetwork

# Legitimate client configuration

**.client.numApps = 1

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

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

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

**.client.app[0].sendInterval = 2s

# Server configuration

**.server.numApps = 1

**.server.app[0].typename = “UdpSink”

# Attacker configuration

**.attacker.numApps = 1

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

# IDS configuration

**.monitor.numApps = 1

**.monitor.app[0].typename = “IntrusionDetector”

# Simulation time

sim-time-limit = 100s

  1. Run the Simulation
  • Launch the simulation in OMNeT++.
  • Observe:
    • Legitimate communication among the client and server for the process.
    • Created the Malicious congestion through the attacker.
    • IDS finding the logs if implemented.
  1. Analyze Results

Metrics to Evaluate:

  1. Packet Delivery Ratio (PDR):
    • Rate of legitimate packets effectively are delivered in the server.
  2. Latency:
    • Calculate the delay caused through congestion for malicious.
  3. Intrusion Detection Rate:
    • Accuracy for IDS in recognizing the malicious packets for IDR.

Visualization:

  • Use OMNeT++’s built-in tools we observe the congestion models.
  • Create a graph view the effect for the network.
  1. Enhance the Project

Step 9.1: Simulate Advanced Attacks

  • Distributed Intrusion: Use several attacker nodes we replicate the synchronized attacks.
  • MITM: Interrupt the replicate and tampering by legitimate congestion.
  • DoS: Overcome the server by congestion of DoS.

Step 9.2: Explore Defense Mechanisms

  • Rate Limiting: Finding the received packets for mitigates the DoS.
  • Anomaly Detection: Utilized their statistical technique we find the unusual congetion designs
  • Encryption: Avoid the MITM and eavesdropping attacks.

Step 9.3: Add Mobility

  • Use INET’s mobility modules we replicate the dynamic network such as mobile nodes.

Example Output

  • Before Attack: General congestion flows among the client and server.
  • During Attack: Intrusion packets are disrupting the legitimate traffic.
  • IDS Logs: Logs intrusion efforts and warnings the network for the IDS.
