Keystroke Logging System

Project Overview

The Keystroke Logging System is an educational cybersecurity project developed to explore how endpoint-generated events can be collected, transmitted, stored, and analyzed through a centralized logging architecture.

The project demonstrates fundamental concepts used in cybersecurity research, digital forensics, security monitoring, and malware analysis by implementing a client-server model that captures user-generated events and securely transmits them to a centralized server for storage and analysis.

Developed using Python, Node.js, and Express.js, the project provided practical experience with network communication, event handling, logging systems, and client-server application development.

⚡ Built for cybersecurity education, research, and controlled laboratory environments.


System Architecture

The system follows a client-server architecture: Architecture

Client Component

The client application is responsible for:

  • Monitoring keyboard events
  • Capturing event data locally
  • Formatting collected information
  • Transmitting data to the server through HTTP requests

Server Component

The server is responsible for:

  • Receiving incoming client data
  • Processing transmitted information
  • Storing collected logs
  • Providing centralized log management

Communication Layer

  • HTTP-based communication
  • Structured data exchange
  • Lightweight client-server interaction
  • Centralized collection model

Key Features

Event Monitoring

Captures and processes endpoint-generated keyboard events for educational analysis and research purposes.

Centralized Log Collection

Demonstrates how data from distributed clients can be aggregated and stored on a central server.

Network Communication

Implements communication between client and server components using HTTP requests.

Real-Time Data Transmission

Supports near real-time transfer of collected events from client to server.

Modular Architecture

Designed with separate client and server components to improve maintainability and scalability.
