Java Network Intrusion Detection System (NIDS)

Overview

The Java Network Intrusion Detection System (NIDS) is a real-time traffic analysis and monitoring tool designed to detect suspicious activities within a network. It utilizes Pcap4J for packet capturing and JavaFX for a user-friendly interface, enabling security analysts to identify potential threats effectively.

Features

• Real-time packet capturing using Pcap4J.
• Traffic analysis and visualization with JavaFX.
• Detection of malicious patterns based on predefined rules.
• Logging of suspicious activities for further investigation.
• User-friendly interface for monitoring network traffic.

Installation

Prerequisites

Ensure you have the following installed on your system:

• Java Development Kit (JDK) 11+
• Pcap4J library
• JavaFX library
• WinPcap/libpcap (depending on your OS)

Setup

1. Clone the repository:

   git clone https://github.com/AbdrrahimDahmani/Java-Network-Intrusion-Detection-System.git
   cd Java-Network-Intrusion-Detection-System

2. Install dependencies:
   • Add Pcap4J and JavaFX to your project's classpath.
   • Ensure your system has WinPcap (Windows) or libpcap (Linux/Mac) installed.
3. Compile and run the project:

   javac -cp ".;lib/*" src/Main.java
   java -cp ".;lib/*" src.Main

Usage
