15. Security Configuration Recommendations

  • Change default administrative credentials during initial deployment and restrict management access to trusted networks.
  • Enable the firewall or ACL and disable unnecessary services and ports.
  • Use a prevailing TLS version and disable unsafe SSH/TLS cipher suites.
  • Retain audit records for remote upgrades, configuration changes and administrator operations.
  • Regularly review CPU, memory, storage, network and LoRa communication-quality alarms.
