🛡 SentinelLite

A Lightweight Endpoint Security Analyzer with Risk Scoring & Interactive Dashboard

SentinelLite is a Python-based security analysis tool that inspects your local system for potential risks and presents a structured security assessment through an interactive web dashboard. It is designed to demonstrate practical concepts in system security, risk modeling, and monitoring.

---

🚀 Overview

Modern systems often run multiple services and processes that can unintentionally expose vulnerabilities. SentinelLite helps identify these risks by analyzing:

• Open network ports
• Running processes
• Firewall status
• Privilege levels

It then converts this data into a quantified risk score, along with actionable recommendations.

✨ Key Features

🔍 System Inspection

• Detects open/listening ports
• Identifies privilege level (user vs admin/root)
• Checks firewall status
• Flags potentially suspicious processes

🧠 Risk Scoring Engine

• Context-aware scoring model
• Differentiates between common and suspicious ports
• Includes process-based risk signals
• Produces a structured risk breakdown

🛡 Security Recommendations

• Generates targeted hardening suggestions
• Based directly on detected system conditions

📊 Interactive Dashboard

• Real-time risk score display
• Category-wise breakdown visualization
• Recommendations panel
• Clean and minimal UI powered by Flask + Chart.js

🧠 How Risk Scoring Works

The total risk score (0–100) is derived from multiple weighted factors:

Category	Description
Privilege	Elevated privileges increase risk
Ports	Suspicious ports carry higher weight
Firewall	Disabled firewall significantly increases risk
Processes	Suspicious processes raise risk
Services	Higher system exposure increases score

---

⚠️ Limitations

• Snapshot-based analysis (no real-time monitoring yet)
• Limited OS-specific recommendations
• No external vulnerability (CVE) integration
• Basic process detection using keyword matching

---

🔮 Future Roadmap

• Real-time monitoring and alert system
• Advanced process behavior analysis
• Integration with threat intelligence sources
• Authentication for dashboard access
• OS-specific security hardening automation
