Stream-Syntra follows semantic versioning. Security updates are provided for the following versions:

• Container Isolation: All services run in isolated Docker containers
• Network Segmentation: Internal container networking with controlled port exposure
• Authentication: Grafana dashboard protected with credentials
• Access Control: QuestDB console and Kafka Connect API accessible only via configured ports
• Environment Variables: Sensitive configuration managed through environment variables

This is a development and learning platform. For production deployment:

• Authentication: Implement proper authentication for all services
• TLS/SSL: Enable encryption for all inter-service communication
• Network Security: Use proper firewall rules and network policies
• Access Control: Implement role-based access control (RBAC)
• Secrets Management: Use dedicated secrets management solutions
• Monitoring: Implement security monitoring and alerting

We take security seriously. If you discover a security vulnerability, please follow responsible disclosure:

DO NOT create public GitHub issues for security vulnerabilities.

Instead, please email: security@stream-syntra.dev (or your actual security contact)

Include:

• Description: Clear description of the vulnerability
• Impact: Potential security impact and affected components
• Reproduction: Step-by-step reproduction instructions
• Environment: Version information and environment details
• Fix Suggestion: If you have a proposed solution

• 24 hours: Initial acknowledgment
• 72 hours: Initial assessment and severity classification
• 7 days: Detailed response with timeline for fix
• 30 days: Target resolution for critical vulnerabilities

Security researchers who responsibly disclose vulnerabilities will be:

• Credited: In release notes and security advisories (if desired)
• Recognized: In our security hall of fame
• Connected: LinkedIn recommendations for significant findings

If deploying Stream-Syntra in production environments:

# Example: Grafana with authentication
environment:
  - GF_SECURITY_ADMIN_PASSWORD=secure_random_password
  - GF_AUTH_ANONYMOUS_ENABLED=false
  - GF_AUTH_BASIC_ENABLED=true

# Example: QuestDB with TLS
environment:
  - QDB_HTTP_TLS_ENABLED=true
  - QDB_HTTP_TLS_CERT_PATH=/path/to/cert
  - QDB_HTTP_TLS_KEY_PATH=/path/to/key

# Example: Restricted network access
networks:
  stream_syntra_internal:
    driver: bridge
    internal: true
  stream_syntra_public:
    driver: bridge

# Use Docker secrets instead of environment variables
echo "my_secret_token" | docker secret create github_token -

We recommend regular security scanning:

# Scan Docker images for vulnerabilities
docker scan questdb/questdb:8.3.1
docker scan confluentinc/cp-kafka:7.7.0
docker scan grafana/grafana-oss:11.2.0

# Python dependencies
pip-audit

# Node.js dependencies  
npm audit

# Java dependencies
mvn org.owasp:dependency-check-maven:check

Implement monitoring for:

• Failed Authentication: Track failed login attempts
• Unusual Access Patterns: Monitor for suspicious data access
• Resource Usage: Watch for abnormal resource consumption
• Network Traffic: Monitor inter-service communication
• Data Exfiltration: Track large data downloads

Keep all components updated:

# Update Docker images regularly
docker-compose pull
docker-compose up -d

# Monitor for security advisories
# - QuestDB: https://github.com/questdb/questdb/security/advisories
# - Kafka: https://kafka.apache.org/cve-list
