3. Network Security Considerations
Essential network security measures for hosting cryptocurrency nodes include:
- Firewall Configuration: Restrict access to necessary ports and IPs.
- VPN and Encrypted Connections: Use VPNs and secure SSH with key-based authentication.
- Network Segmentation: Isolate nodes from the main network using VLANs or DMZs.
- Regular Updates and Patching: Keep node software, Docker images, and the underlying OS updated.
- Monitoring and Logging: Implement logging, monitoring, and intrusion detection systems.
- Access Control: Enforce strict user management and multifactor authentication (MFA).
- Backup and Disaster Recovery: Regularly back up data and have a disaster recovery plan.
- Network Hardening: Disable unnecessary services and follow best practices.
- Rate Limiting and DDoS Protection: Implement rate limiting and consider DDoS protection services.
- Secure Configuration of Docker: Isolate containers and avoid root privileges.
