Portable Log Analysis Tool for Isolated Networks

---

Project Overview

Continuous monitoring of systems and networks is crucial to detect, prevent, and respond to cybersecurity threats.
While Security Operation Centers (SOC) monitor networks in real-time, isolated networks require portable, self-contained tools for offline log collection, analysis, and reporting.

This project aims to build a portable log analysis tool for isolated networks with the following key features:

• Cross-platform portability (Windows, Linux, Mac)
• Multi-source log collection (Syslog, Event Logs, USB devices, network traffic)
• Log parsing and normalization
• Anomaly & threat detection
• Offline web-based dashboard
• Secure encryption & authentication
• Reporting and export capabilities
