# IDS - Intrusion Detection System # IDS - Intrusion Detection System
Sistema di rilevamento intrusioni per router MikroTik basato su Machine Learning. ## Overview
This project is a full-stack web application designed as an Intrusion Detection System (IDS) for MikroTik routers, leveraging Machine Learning. Its primary purpose is to monitor network traffic, detect anomalies indicative of intrusions, and automatically block malicious IP addresses across multiple routers. The system aims to provide real-time monitoring, efficient anomaly detection, and streamlined management of network security for MikroTik environments.
## Progetto
**Tipo**: Full-stack Web Application + Python ML Backend
**Stack**: React + FastAPI + PostgreSQL + MikroTik API REST
## Architettura
### Frontend (React)
- Dashboard monitoring real-time
- Visualizzazione detections e router
- Gestione whitelist
- ShadCN UI components
- TanStack Query per data fetching
### Backend Python (FastAPI)
- **ML Analyzer**: Isolation Forest con 25 feature mirate
- **MikroTik Manager**: Comunicazione API REST parallela con 10+ router
- **Detection Engine**: Scoring 0-100 con 5 livelli di rischio
- Endpoints: /train, /detect, /block-ip, /unblock-ip, /stats
### Backend Node.js (Express)
- API REST per frontend
- Gestione database PostgreSQL
- Routes: routers, detections, logs, whitelist, training-history
### Database (PostgreSQL)
- `routers`: Configurazione router MikroTik
- `network_logs`: Log syslog da router
- `detections`: Anomalie rilevate dal ML
- `whitelist`: IP fidati
- `training_history`: Storia training modelli
## Workflow
1. **Log Collection**: Router → Syslog (UDP:514) → RSyslog → syslog_parser.py → PostgreSQL `network_logs`
2. **Training**: Python ML estrae 25 feature → Isolation Forest
3. **Detection**: Analisi real-time → Scoring 0-100 → Classificazione
4. **Auto-Block**: IP critico (>=80) → API REST → Tutti i router (parallelo)
## Fix Recenti (Novembre 2025)
### ✅ Database Driver Fix - Dual Mode Neon/PostgreSQL (21 Nov 2025 - 17:40)
- **Problema**: Frontend Node.js falliva con errore 500 su tutte le query database (`/api/stats`, `/api/routers`, ecc.)
- **Causa ROOT**: `@neondatabase/serverless` usa WebSocket ed è compatibile SOLO con Neon Cloud, non con PostgreSQL locale su AlmaLinux
- **Diagnosi**:
- ✅ DATABASE_URL caricato correttamente (verificato con `psql`)
- ✅ Backend Python funzionava (usa `psycopg2` compatibile con PostgreSQL locale)
- ❌ Backend Node.js falliva (usava `@neondatabase/serverless`)
- **Soluzione**:
- Modificato `server/db.ts` per **dual-mode**:
- Su Replit (Neon Cloud): usa `@neondatabase/serverless` + WebSocket
- Su AlmaLinux (PostgreSQL locale): usa `pg` standard driver
- Auto-detection basata su `DATABASE_URL.includes('neon.tech')`
- Import corretto `pg` per ES modules: `import pg from 'pg'; const { Pool } = pg;`
- Aggiunto health-check database: `SELECT 1` all'avvio
- Aggiunto logging dettagliato errori DB: `[DB ERROR]` prefix in `server/routes.ts`
- **Fix Schema Database**:
- Problema secondario: tabella `routers` mancava colonne `api_port` e `last_sync`
- Risolto con `ALTER TABLE routers ADD COLUMN IF NOT EXISTS ...`
- **Risultato Finale**:
- ✅ Replit: `📦 Using Neon serverless database` + `✅ Database connection successful`
- ✅ AlmaLinux: `🐘 Using standard PostgreSQL database` + `✅ Database connection successful`
- ✅ API database: Tutte le route `/api/*` rispondono **200 invece di 500**
- ✅ Test completo: Training avviato con successo `POST /api/ml/train 200`
- ✅ Logging diagnostico: `[DB ERROR]` prefix ha permesso debug rapido errori schema
### ✅ Frontend Environment Variables Fix (21 Nov 2025 - 17:00)
- **Problema**: Frontend Node.js non si avviava su server AlmaLinux con errore `DATABASE_URL must be set`
- **Causa 1**: Script `check_frontend.sh` non caricava variabili d'ambiente dal file `.env`
- **Causa 2**: Il comando `nohup` crea un nuovo processo che non eredita variabili esportate con `source`
- **Soluzione**:
- Modificato `deployment/check_frontend.sh` per passare variabili direttamente al comando npm
- Usato `env $(cat .env | grep -v '^#' | xargs) npm run dev` per iniettare variabili nel processo
- **Risultato**: Frontend si avvia correttamente leggendo `DATABASE_URL` e altre variabili da `.env`
### ✅ Form Validation Migliorata (21 Nov 2025 - 15:00)
- **API ML Endpoints**: Timeout configurabili (120s train/detect, 10s stats), validazione input, messaggi errore specifici (504 timeout, 503 backend down, 400 validation)
- **Whitelist Form**: Convertito a react-hook-form + zodResolver, validazione IP completa (regex + controllo ottetti 0-255)
- **Training Forms**: Due form separati (trainForm/detectForm), schema Zod con z.coerce.number(), FormDescription per suggerimenti
### ✅ Sistema Completamente Funzionante (17 Nov 2025 - 19:30)
- **Backend Python FastAPI**: ✅ Porta 8000, modello ML caricato, endpoint /stats funzionante
- **Database PostgreSQL**: ✅ 5 tabelle (network_logs, detections, routers, whitelist, training_history)
- **Syslog Parser**: ✅ Funzionante, log salvati continuamente
- **Pattern Regex**: ✅ Match rate 99.9% su log MikroTik reali
- **ML Detection**: ✅ Modello Isolation Forest addestrato, pronto per detection automatica
- **Deployment**: ✅ Git workflow automatizzato con `push-gitlab.sh` e `update_from_git.sh --db`
### Backend FastAPI Fix (17 Nov 2025 - 19:30)
- **Problema**: Endpoint `/stats` falliva con errore 500
- **Causa 1**: Colonna `logged_at` non esiste (nome corretto: `timestamp`)
- **Causa 2**: Tabella `routers` mancante
- **Causa 3**: Query non gestivano risultati `None`
- **Soluzione**:
- Corretto nome colonna da `logged_at` a `timestamp` in `/stats`
- Creato script SQL `database-schema/create_routers.sql`
- Aggiunta gestione `None` per tutte le query
- **Risultato**: Endpoint `/stats` funzionante, API completa operativa
### Crontab Automation Fix (18 Nov 2025 - 09:30)
- **Problema 1**: Training/Detection crontab falliscono con `ModuleNotFoundError: No module named 'requests'`
- **Problema 2**: Script check_backend/frontend falliscono con `Permission denied` su `/var/run/ids/`
- **Causa 1**: Crontab usavano Python inline con modulo `requests` non installato
- **Causa 2**: Utente `ids` non ha permessi scrittura su `/var/run/ids/`
- **Soluzione**:
- Creati script shell dedicati: `cron_train.sh` e `cron_detect.sh` (usano `curl` invece di Python)
- Aggiornati script monitoring: `check_backend.sh` e `check_frontend.sh` (usano `/var/log/ids/` invece di `/var/run/ids/`)
- Aggiornato `setup_crontab.sh` per usare i nuovi script
- **Risultato**: Automazione crontab completamente funzionante senza dipendenze Python esterne
### Schema Database Fix (17 Nov 2025)
- **Problema**: Tabella `network_logs` mancante, schema TypeScript disallineato con Python
- **Soluzione**: Schema aggiornato con campi corretti (router_name, destination_ip/port, packet_length, raw_message)
- **Script SQL**: `database-schema/create_network_logs.sql` per creazione tabella
- **Update automatico**: `./update_from_git.sh --db` applica tutti gli script SQL in `database-schema/`
### Pattern Regex Fix (17 Nov 2025)
- **Problema**: Pattern regex non matchavano formato reale log MikroTik
- **Formato vecchio**: `src-address=IP:PORT dst-address=IP:PORT proto=UDP`
- **Formato reale**: `proto UDP, IP:PORT->IP:PORT, len 1280`
- **Risultato**: Match rate 99.9%, ~670K log salvati correttamente
### PostgreSQL Authentication Fix
- **Problema**: Password authentication failed (SCRAM-SHA-256 vs MD5)
- **Soluzione**: `deployment/fix_postgresql_auth.sh` configura SCRAM-SHA-256 in pg_hba.conf
- **Password encryption**: ALTER SYSTEM SET password_encryption = 'scram-sha-256'
- **Utente ricreato**: DROP + CREATE con formato SCRAM corretto
### IPv4 Force Fix
- **Problema**: syslog_parser si connetteva a ::1 (IPv6) invece di 127.0.0.1 (IPv4)
- **Soluzione**: PGHOST=127.0.0.1 in .env (NON usare localhost)
- **Parser**: load_dotenv() carica .env automaticamente
### Git Ownership Fix
- **Problema**: dubious ownership error in /opt/ids
- **Soluzione**: `deployment/fix_git_ownership.sh` aggiunge safe.directory
- **Update script**: `deployment/update_from_git.sh` ora esegue git come utente ids

## System Architecture
The IDS features a React-based frontend for real-time monitoring, detection visualization, and whitelist management, utilizing ShadCN UI and TanStack Query. The backend comprises a Python FastAPI service for ML analysis (Isolation Forest with 25 targeted features), MikroTik API management, and a detection engine scoring anomalies from 0-100 with five risk levels. A Node.js (Express) backend handles API requests from the frontend and manages the PostgreSQL database.
**Workflow:**
1. **Log Collection**: MikroTik Routers send syslog data (UDP:514) to RSyslog, which is then parsed by `syslog_parser.py` and stored in the `network_logs` table in PostgreSQL.
2. **Training**: The Python ML component extracts 25 features from network logs and trains an Isolation Forest model.
3. **Detection**: Real-time analysis of network logs is performed using the trained ML model, assigning a risk score.
4. **Auto-Block**: Critical IPs (score >= 80) are automatically blocked across all configured MikroTik routers in parallel via their REST API.
**Key Features:**
- **ML Analyzer**: Isolation Forest with 25 features.
- **MikroTik Manager**: Parallel communication with 10+ routers via API REST.
- **Detection Engine**: Scoring 0-100 with 5 risk levels (Normal, Basso, Medio, Alto, Critico).
- **Form Validation**: Improved validation using react-hook-form and Zod.
- **Database Migrations**: Automated SQL migrations applied via `update_from_git.sh --db`.
- **Microservices**: Separation of concerns with dedicated Python ML backend and Node.js API backend.
## External Dependencies
- **React**: Frontend framework.
- **FastAPI**: Python web framework for the ML backend.
- **PostgreSQL**: Primary database for storing router configurations, network logs, detections, and whitelist entries.
- **MikroTik API REST**: Used for communication with MikroTik routers for configuration and IP blocking.
- **ShadCN UI**: Frontend component library.
- **TanStack Query**: Data fetching library for the frontend.
- **Isolation Forest**: Machine Learning algorithm for anomaly detection.
- **RSyslog**: Log collection daemon.
- **Drizzle ORM**: Used for database schema definition and synchronization in the Node.js backend.
- **Neon Database**: Cloud-native PostgreSQL service (used in Replit environment).
- **pg (Node.js driver)**: Standard PostgreSQL driver for Node.js (used in AlmaLinux environment).
- **psycopg2**: PostgreSQL adapter for Python.
## Fix Recenti (Novembre 2025)
### 🚨 Database Full - Auto-Cleanup Fix (21 Nov 2025 - 18:00)
- **Problema**: Database PostgreSQL pieno con **417 MILIONI di log** accumulati
- Syslog parser ha processato 417.7M righe senza limite di retention
- Errore: `could not extend file: No space left on device`
- Tutte le tabelle vuote perché database non accetta più scritture
- **Causa**: Nessuna pulizia automatica dei vecchi log (retention infinita)
- **Soluzione**:
- Script `cleanup_old_logs.sql`: Mantiene solo ultimi 7 giorni di `network_logs`
- Script `cleanup_database.sh`: Wrapper per esecuzione manuale/cron
- Script `setup_cron_cleanup.sh`: Configura cron job giornaliero (ore 03:00)
- **Fix Immediato sul Server**:
```bash
# 1. Pulisci manualmente log vecchi
psql $DATABASE_URL << 'EOF'
DELETE FROM network_logs WHERE timestamp < NOW() - INTERVAL '7 days';
VACUUM FULL network_logs;
EOF
# 2. Setup pulizia automatica giornaliera
sudo /opt/ids/deployment/setup_cron_cleanup.sh
```
- **Risultato Atteso**:
- Database ridotto da centinaia di GB a pochi GB
- Retention 7 giorni sufficiente per training ML
- Pulizia automatica previene saturazione futura
### ✅ Database Driver Fix - Dual Mode Neon/PostgreSQL (21 Nov 2025 - 17:40)
- **Problema**: Frontend Node.js falliva con errore 500 su tutte le query database
- **Causa**: `@neondatabase/serverless` usa WebSocket ed è compatibile SOLO con Neon Cloud, non con PostgreSQL locale
- **Soluzione**: Dual-mode driver in `server/db.ts` con auto-detection ambiente
- **Risultato**: Funziona su Replit (Neon) e AlmaLinux (PostgreSQL standard) ✅
