How to Start Intrusion Detection System Projects using OMNeT++

To creating an Intrusion Detection System (IDS) project using OMNeT++ has includes the designing for replicating the execution systems we finding the unauthorized assigns or malicious activities in a network. The IDS projects can be concentrating the finding particular attacks and examine the designs or enhancing the accuracy and efficiency of finding the mechanisms.

Here’s a step-by-step demonstrate the Intrusion Detection System for under steps for followed:

Steps to Start Intrusion Detection System Projects using OMNeT++

Step 1: Understand Intrusion Detection Systems

Key Types of IDS:

  1. Network-Based IDS (NIDS):
    • Observe the network traffic for malicious activity.
  2. Host-Based IDS (HIDS):
    • Follow on the activities on a precise system or device.

Detection Methods:

  • Signature-Based: Matches identified the attack patterns for based on the signature.
  • Anomaly-Based: Classifies the deviations from the normal behaviour.
  • Hybrid: Associates the signature and anomaly-based finding on the hybrid.

Common Use Cases:

  • Finding the DDoS, MITM, or spoofing attacks.
  • Observing the IoT networks for anomalies.
  • Securing the wireless networks against unauthorized assigns.

Step 2: Define the Project Scope

Focus on a specific IDS application:

  • Attack Detection: Replicate the particular attacks and calculates the IDS efficiency for finding the attacks.
  • Traffic Analysis: Observe the normal vs. anomalous traffic patterns.
  • Machine Learning: Used the Machine learning and AI we improve the detection accuracy.
  • Wireless Network IDS: Finding the intrusions in Wi-Fi or IoT environments.

Example Problem Statement:

  • For sample: “Design and evaluate an anomaly-based intrusion detection system to detect DDoS attacks in a wireless sensor network.”

Step 3: Prepare the OMNeT++ Environment

  1. Install OMNeT++:
    • Download and set up OMNeT++.
  2. Install INET Framework:
    • INET offers the networking protocols and tools for replicating the wired and wireless networks.
  3. Optional Add-Ons:
    • Castalia: Intended for IoT and wireless sensor networks.
    • SimuLTE: Designed for LTE/5G network simulations.

Step 4: Develop the Network Model

Define Topology:

  • Nodes:
    • It contains the nodes for clients, servers, routers, and potential attackers.
  • IDS Nodes:
    • It placed the IDS modules on key nodes such as routers, gateways.

Traffic Models:

  • Replicate the normal traffic such as HTTP requests, file transfers.
  • Enhance the malicious congestion for sample high-volume traffic for DDoS attacks, spoofed packets.

Step 5: Implement the IDS

Signature-Based IDS:

  1. Pattern Matching:
    • Build a database of identified the attack signatures.
    • Execute the logic and we associate the incoming traffic against signatures.

Anomaly-Based IDS:

  1. Baseline Behaviour:
    • Train the system on normal traffic designs for baseline behaviours.
  2. Detection Logic:
    • Flag deviations from the baseline as potential intrusions.

Hybrid IDS:

  • Combined the above techniques for additional robust finding.

Attack Simulation:

  • DDoS:
    • Replicate the attackers creating the high traffic volumes.
  • Man-in-the-Middle (MITM):
    • Man-in-the-Middle replicate the interruption and tampering of packets.
  • Packet Spoofing:
    • Transmit the packets through forged source IPs.

Step 6: Configure the Simulation

Edit the omnetpp.ini File:

  • Network Settings:
    • Describe the node count of traffic types and connection parameters.
  • IDS Parameters:
    • Setting the thresholds for anomaly findings or signature matching.
  • Attack Parameters:
    • Configure the attack types of durations and intensities.

Example Configuration:

[General]

network = IDSNetwork

sim-time-limit = 100s

*.gateway.enableIDS = true

*.gateway.idsType = “AnomalyBased”

*.attacker.trafficRate = 500kbps

*.logger.outputFile = “traffic_log.pcap”

Step 7: Run Simulation Scenarios

Example Scenarios:

  1. Attack Detection:
    • Replicate the normal and attack traffic we calculate the IDS accuracy for finding.
  2. Anomaly Threshold Testing:
    • Validate the different thresholds for finding anomalies.
  3. Performance Analysis:
    • Calculate the IDS performance below the various traffic loads.

Step 8: Analyze Results

Key Metrics:

  • Detection Accuracy: Percentage of attacks detected in the accuracy.
  • False Positive Rate: Legitimate the traffic flagged as malicious.
  • Latency: Time taken we detect the intrusion for latency.
  • Throughput: Network performance with IDS ensure the throughput.

Tools for Analysis:

  • Wireshark: Examine the seized congestion logs.
  • Python/MATLAB: Intended for visualizing metrics and designs.

Step 9: Enhance with Advanced Features

  1. Machine Learning:
    • Utilized the machine learning techniques are supervised or unsupervised learning for anomaly finding.
    • Tested the Machine Learning designs on historical network data.
  2. Distributed IDS:
    • Organize the IDS modules with several nodes for combined finding.
  3. Blockchain for Forensics:
    • Store the logs securely for post-incident examine the blockchain for forensics.
  4. Real-Time Detection:
    • Execute the low-latency finding the mechanisms for real-time response.

Step 10: Document and Refine

  • Document the Design:
    • Contain the procedures about the topology for IDS implementation and attack scenarios.
  • Analyze and Iterate:
    • Improve the thresholds of algorithms or setting based on results.
  • Visualize Results:
    • Build a graph or charts we showcase finding the accuracy and performance.

Example Use Case: Anomaly-Based IDS for IoT Networks

  1. Scenario:
    • Replicate the IoT network through periodic traffic and a DDoS attack.
  2. Objective:
    • Finding the anomalies caused through the attack and estimate the IDS efficiency.
  3. Evaluation:
    • Calculate the detection accuracy of false positive rate and response time.
