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)

• All 17 MozDef images present locally
• No image pulls required during startup
• All images self-contained

Verification:

docker images mozdef/* | wc -l
# Should show 17 images

2. Service Dependencies (Internal Only)

• All services use internal Docker network
• Service discovery via Docker service names
• No external DNS lookups
• 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)

• No hardcoded external URLs
• All references use service names
• No external package repositories
• No external API endpoints

4. Bootstrap Process (Offline)

• Initial setup uses local Elasticsearch
• No external downloads during bootstrap
• All templates and configs local

🔍 Verification Tests

Test 1: Start Services Without Internet

# 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

# 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)

# 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)

# 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
