# 🛡️ DDoS Detection System

Detect DDoS attacks in real-time using **Packets Per Second (PPS)** calculation.

## How It Works

Enter two values from your network flow data:
- **Flow Duration** — how long the flow lasted (in microseconds)
- **Total Packets** — total number of packets in the flow

The system calculates PPS and classifies the traffic instantly.

## Threat Levels

| PPS Range | Status |
|-----------|--------|
| < 500 | ✅ NORMAL |
| 500 – 2,000 | ⚠️ SUSPICIOUS |
| 2,000 – 10,000 | 🚨 HIGH TRAFFIC |
| > 10,000 | 🔥 DDoS ATTACK! |

## Example Inputs

| Flow Duration (µs) | Total Packets | PPS | Result |
|--------------------|---------------|-----|--------|
| 1,000,000 | 100 | 100 | ✅ NORMAL |
| 100,000 | 100 | 1,000 | ⚠️ SUSPICIOUS |
| 10,000 | 100 | 10,000 | 🚨 HIGH TRAFFIC |
| 98 | 15 | 153,061 | 🔥 DDoS ATTACK! |
