Design Principles

The connector follows least-privilege behavior and avoids unnecessary host-level surface area.

Operations are limited to required sync functions and status heartbeats.

Operational Controls

For external access scenarios, controlled networking is essential. VPN-first access remains the recommended production posture.

  • Read-only source interaction
  • Encrypted transport channels
  • Controlled endpoint communication
  • Firewall and network policy recommendations

Incident Readiness

Teams should maintain basic runbooks for connectivity incidents and credential rotation.

Preventive controls and observability are more effective than reactive troubleshooting.
