8. Security Considerations

  • Protect private keys—store only public verification keys in OTP; private keys remain in secure manufacturing environment.
  • Disable debug interfaces (JTAG/serial) in production where possible; if required, protect with fuses or OTP flags.
  • Harden network services: reduce open ports, disable Telnet in favor of SSH (key-based), rate-limit update endpoints.
  • Enforce least-privilege for processes; use sandboxing for plugins/CA modules.
