ARP Detector: Real-Time Network Security Tool

This code is a basic graphical user interface (GUI) application designed to detect ARP spoofing attacks on a network. It features a simple layout with a text box for the user to input the desired detection timeout and a 'Start' button. Upon clicking the 'Start' button, an instance of the ArpDetectorPage class is initiated, triggering the detection process. This class actively scans the network and identifies any instances of ARP spoofing, alerting the user through appropriate messages. The application utilizes Python's Tkinter library for GUI creation.

Here's a breakdown of the code:

1. ArpDetectorPage class: This class handles the core functionality of detecting ARP spoofing attacks. It defines the following functions:

   • __init__: Initializes the class by setting up variables like the network interface, IP and MAC address mappings, and event handling for starting and stopping detection.

   • start_detection: Starts the detection process by launching a separate thread to continuously scan the network for ARP spoofing attempts. It also updates the UI to reflect the running state.

   • stop_detection: Stops the detection process by signaling the thread to terminate and updating the UI accordingly.

   • run: This is the main loop that continuously scans the network and analyzes ARP packets to identify potential spoofing activities. It sends ARP requests to each IP address on the network and compares the received MAC addresses with the stored mapping to detect discrepancies.

   • scan_network: This method scans the network by sending ARP requests to each IP address on the network and storing the received MAC addresses in a dictionary.

   • detect_arp_spoofing: Compares the MAC addresses received from ARP responses with the stored mapping to detect potential spoofing activities.

2. ArpDetectorPageUI class: This class is responsible for creating the user interface of the application using Tkinter.

   • __init__: Initializes the UI by setting up a window with an entry box for the detection timeout and a 'Start' button.

   • start_detection: Reads the timeout value from the entry box, closes the UI window, and creates an instance of the ArpDetectorPage class to initiate the detection process.

The code showcases a basic approach to network security by implementing ARP spoofing detection. However, it's essential to note that this is a simplified example. For production-level security, it's crucial to consult with security professionals and use more sophisticated tools and techniques to effectively protect your network.
