marco370 369c268bc1 Update deployment instructions and network log schema
Refactor `replit.md` to include `./push-gitlab.sh` deployment. Update `shared/schema.ts` and `database-schema/create_network_logs.sql` to change `routerId` to `routerName` in `networkLogs`, remove the relation, and update fields like `destIp` to `destinationIp`, `bytes`/`packets` to `packetLength`, and add `rawMessage`.

IDS - Intrusion Detection System

Sistema di rilevamento intrusioni per router MikroTik basato su Machine Learning.

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)

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

Deployment e Aggiornamenti

PRIMO DEPLOYMENT (Bootstrap) - Server AlmaLinux

Documentazione: deployment/BOOTSTRAP_PRIMO_DEPLOYMENT.md

# Clone in directory separata (preserva .env esistente)
cd /opt
sudo -u ids git clone https://[CREDENTIALS]@git.alfacom.it/marco/ids.git ids_git

# Copia .env esistente
sudo -u ids cp /opt/ids/.env /opt/ids_git/.env

# Swap atomico directory
mv /opt/ids /opt/ids_legacy
mv /opt/ids_git /opt/ids

# Installa dipendenze e riavvia servizi
cd /opt/ids
sudo -u ids npm install
cd python_ml && sudo -u ids pip3.11 install -r requirements.txt

Aggiornamenti Futuri (Dopo Bootstrap)

# Aggiornamento standard (codice + dipendenze)
cd /opt/ids
./update_from_git.sh

# Aggiornamento con sincronizzazione schema database
./update_from_git.sh --db

IMPORTANTE: update_from_git.sh fa backup automatico di .env e git.env prima del pull!

Export Schema Database (Solo Struttura)

# Su server production, esporta schema per commit su git
cd /opt/ids/deployment
./export_db_schema.sh

# Risultato: database-schema/schema.sql (NO dati, SOLO DDL)

Push su Git (Da Replit)

# Esporta schema + commit + push
cd /opt/ids
./push-gitlab.sh          # Patch version (1.0.0 → 1.0.1)
./push-gitlab.sh minor    # Minor version (1.0.5 → 1.1.0)
./push-gitlab.sh major    # Major version (1.1.5 → 2.0.0)

Comandi Utili

Start Python Backend

cd python_ml
pip install -r requirements.txt
python main.py

Configurazione Router MikroTik

Abilita API REST

/ip service
set api-ssl disabled=no
set www-ssl disabled=no

Aggiungi Router

Via dashboard web o SQL:

INSERT INTO routers (name, ip_address, username, password, api_port, enabled)
VALUES ('Router 1', '192.168.1.1', 'admin', 'password', 443, true);

Feature ML (25 totali)

  • avg_packet_size, bytes_per_second

Temporali (8)

  • time_span_seconds, conn_per_second
  • hour_of_day, day_of_week

Livelli di Rischio

  • 🔴 CRITICO (85-100): Blocco immediato
  • 🟠 ALTO (70-84): Blocco + monitoring
  • 🟡 MEDIO (60-69): Monitoring
  • 🔵 BASSO (40-59): Logging
  • 🟢 NORMALE (0-39): Nessuna azione

Vantaggi vs Sistema Precedente

  • Feature: 150+ → 25 (mirate)
  • Training: ~5 min → ~10 sec
  • Detection: Lento → <2 sec
  • Router Comm: SSH → API REST
  • Multi-Router: Sequenziale → Parallelo
  • Database: MySQL → PostgreSQL
  • Falsi Negativi: Alti → Bassi

Note

  • Whitelist: IP protetti da blocco automatico
  • Timeout: Blocchi scadono dopo 1h (configurabile)
  • Parallel Blocking: Tutti i router aggiornati simultaneamente
  • Auto-Training: Configurabile via cron (consigliato ogni 12h)
  • Auto-Detection: Configurabile via cron (consigliato ogni 5 min)

Sicurezza

  • Password router gestite da database (non in codice)
  • API REST più sicura di SSH
  • Timeout automatico blocchi
  • Logging completo operazioni
  • PostgreSQL con connessione sicura

Development

  • Frontend: Workflow "Start application" (auto-reload)
  • Python Backend: python python_ml/main.py
  • API Docs: http://localhost:8000/docs
  • Database: PostgreSQL via Neon (environment variables auto-configurate)

Preferenze Utente

Operazioni Git e Deployment

  • IMPORTANTE: Push su git tramite ./push-gitlab.sh (NON comandi git manuali)
  • Aggiornamenti server: ./update_from_git.sh o ./update_from_git.sh --db
  • Workflow iterativo:
    1. Utente fornisce errori/modifiche dal server AlmaLinux
    2. Agente risolve problemi e modifica file su Replit
    3. Utente esegue ./push-gitlab.sh per commit+push
    4. Utente testa su server con ./update_from_git.sh
    5. Ripeti fino a funzionamento completo
