# MozDef - Offline Mode Verification

## 🎯 Objective
Verify that MozDef can run completely offline without any internet connection or external dependencies.

**Date:** $(date)
**Status:** ✅ Verified - Fully Offline Capable

---

## ✅ Offline Requirements Checklist

### 1. Docker Images (Local)
- [x] All 17 MozDef images present locally
- [x] No image pulls required during startup
- [x] All images self-contained

**Verification:**
```bash
docker images mozdef/* | wc -l
# Should show 17 images
```

### 2. Service Dependencies (Internal Only)
- [x] All services use internal Docker network
- [x] Service discovery via Docker service names
- [x] No external DNS lookups
- [x] No external API calls

**Internal Service Communication:**
- Elasticsearch: `elasticsearch:9200` (internal)
- RabbitMQ: `rabbitmq:5672` (internal)
- MongoDB: `mongodb:3002` (internal)
- Kibana: `kibana:5601` (internal)
- REST API: `rest:8081` (internal)
- Meteor: `meteor:3000` (internal)

### 3. Configuration Files (No External URLs)
- [x] No hardcoded external URLs
- [x] All references use service names
- [x] No external package repositories
- [x] No external API endpoints

### 4. Bootstrap Process (Offline)
- [x] Initial setup uses local Elasticsearch
- [x] No external downloads during bootstrap
- [x] All templates and configs local

## 🔍 Verification Tests

### Test 1: Start Services Without Internet
```bash
# Disconnect internet (or block external access)
# Then start services
cd /root/MozDef
docker-compose -f docker/compose/docker-compose.yml -p mozdef up -d
```

**Expected Result:** ✅ All services start successfully

### Test 2: Internal Service Communication
```bash
# Test Elasticsearch (internal)
docker exec mozdef-elasticsearch-1 curl http://127.0.0.1:9200/_cluster/health

# Test RabbitMQ (internal)
docker exec mozdef-rabbitmq-1 rabbitmqctl status

# Test MongoDB (internal)
docker exec mozdef-mongodb-1 mongo --port 3002 --eval "db.version()"
```

**Expected Result:** ✅ All services respond

### Test 3: Event Processing (Offline)
```bash
# Send event (no internet needed)
curl -X POST http://localhost:8080/events \
  -H "Content-Type: application/json" \
  -d '{
    "timestamp": "'$(date -u +"%Y-%m-%dT%H:%M:%S+00:00")'",
    "utctimestamp": "'$(date -u +"%Y-%m-%dT%H:%M:%S+00:00")'",
    "hostname": "offline-test.com",
    "processname": "test.py",
    "processid": 1234,
    "severity": "INFO",
    "summary": "Offline test",
    "category": "test",
    "source": "test",
    "tags": ["test"],
    "details": {}
  }'

# Verify in Elasticsearch (internal)
docker exec mozdef-elasticsearch-1 curl "http://127.0.0.1:9200/events-*/_search?q=hostname:offline-test.com"
```

**Expected Result:** ✅ Event processed and searchable

### Test 4: Web Interfaces (Offline)
```bash
# Test Meteor (no internet needed)
curl -I http://localhost

# Test Kibana (no internet needed)
curl -I http://localhost:9090/app/kibana
```

**Expected Result:** ✅ Both return HTTP 200
