How to Start ICMP Attack Projects Using OMNeT++
To start an Internet Control Message Protocol (ICMP) attack project in OMNeT++, we follow below steps:
Steps to Start ICMP attack Project in OMNeT++
- Understand the ICMP Attack
- ICMP Attack Definition: Internet Control Message Protocol (ICMP) attacks utilise the ICMP packets for interrupting network functionality. Below is a general instances:
- Ping Flood: To devastate a target, transmit continuous ICMP Echo demands.
- Smurf Attack: Spoofs an IP address and transmits ICMP packets to a propagate address to trigger several replies for overflowing the victim.
- ICMP Redirect: It supports to change the routing tables to transmit traffic via malicious paths.
- Set Up the OMNeT++ Environment
- Install OMNeT++: We should download and install the new version of OMNeT++ IDE on the system.
- Install INET Framework:
- INET framework offers supports to replicate the network protocols with ICMP.
- We adhere to INET installation instructions for combining it including OMNeT++.
- Define Project Scope
- Attack Type:
- Smurf, or ICMP Redirect, Ping Flood.
- Network Topology:
- Nodes: Specify the kinds of nodes such as attackers, victims, routers.
- Connections: Make use of Ethernet, wireless, or hybrid sets up.
- Metrics to Measure:
- CPU/memory usage of victim nodes.
- Packet delivery rate.
- Network latency.
- Plan the Project Workflow
Step 4.1: Design Network Topology
- Exploit the INET Framework or a custom network pattern:
- Nodes: Attacker, victim, intermediary routers.
- Connections: Replicate the behavior of realistic network to utilise links.
- Protocols: IP and ICMP.
Step 4.2: Implement ICMP Attack
- Prolong or alter the PingApp module of INET for replicating the malicious behavior.
- Example:
- Transmit a high frequency of ICMP Echo Requests (Ping Flood).
- Spoof source IPs address for a Smurf attack.
Step 4.3: Configure Defense Mechanisms (Optional)
- Launch the defense approaches like:
- Filtering according to the spoof detection.
- Rate restrictive ICMP packets.
- Coding Steps
Step 5.1: Customize the ICMP Attack
- Fine-tune INET PingApp module for making behavior of attack.
- Sample Code for an ICMP Flood:
#include <omnetpp.h>
#include “inet/common/INETDefs.h”
#include “inet/applications/pingapp/PingApp.h”
using namespace inet;
class IcmpFloodApp : public PingApp {
protected:
virtual void initialize(int stage) override;
virtual void sendPing() override;
};
Define_Module(IcmpFloodApp);
void IcmpFloodApp::initialize(int stage) {
PingApp::initialize(stage);
if (stage == INITSTAGE_APPLICATION_LAYER) {
EV << “ICMP Flood Attack Initialized\n”;
}
}
void IcmpFloodApp::sendPing() {
for (int i = 0; i < 10; ++i) { // Send 10 packets in quick succession
EV << “Sending ICMP flood packet\n”;
PingApp::sendPing();
}
}
Step 5.2: Configure Network Nodes
- In the .ned file, describe the attacker and target nodes:
network IcmpAttackNetwork {
submodules:
attacker: StandardHost;
victim: StandardHost;
router: Router;
connections:
attacker.ethg++ <–> EthernetLink <–> router.ethg++;
router.ethg++ <–> EthernetLink <–> victim.ethg++;
}
- Simulation Configuration
- Specify the simulation metrics using the .ini configuration file:
[Config IcmpAttack]
network = IcmpAttackNetwork
**.attacker.pingApp.destAddr = “victim”
**.attacker.pingApp.startTime = 1s
**.attacker.pingApp.stopTime = 10s
**.attacker.pingApp.sendInterval = 0.01s # High frequency for flood
- Run and Visualize
- Utilise OMNeT++ IDE to execute the simulation.
- Monitor:
- The victim node’s resource consumption like CPU, memory.
- Network congestion and packet loss.
- Extend the Project
- We need to execute more advanced ICMP attacks such as Smurf:
- Make use of transmission addresses and spoofed packets.
- Launch the detection mechanisms for:
- Pattern matching for excessive ICMP traffic.
- Rate restricting or obstructing ICMP Echo demands.
- Metrics and Analysis
- Estimate:
- Network performance before and in the course of the attack.
- Measure the execution defense mechanisms’ success rate.
- Tools:
- Make use of OMNeT++’s data collection or external tools such as Wireshark for analysis.
- Document and Present
- It offers more comprehensive details that has:
- Objectives.
- Implementation details like topology, attack mechanism.
- Outcomes for charts, logs, and metrics.
- Conclusions and potential countermeasures.
In the conclusion, we all know about how to start and simulate the ICMP Attack Projects and how to analyse their performance using OMNeT++ tools through given methods. Further specific insights like coding, configuring the .ned.file or executing the simulation will be offered.
