summary: 'Synse Server publishes NO application-level authentication or authorization. The platform overview
  states this outright under ''What Synse Does Not Provide'': ''Access control to plugins/devices.'' Every
  documented HTTP and WebSocket operation, including the two write operations that act on physical hardware,
  is unauthenticated. Security is transport-level and is the operator''s responsibility.'

  note: 'The docs recommend a TLS-terminating frontend such as Nginx for production rather than the built-in
    option: ''While this may work for small/personal use cases, it is recommended to use a more robust
    TLS termination frontend for it in production.'''
- name: plugin gRPC TLS
  description: The internal Synse Server to plugin gRPC channel can be secured with TLS.

  note: Synse performs no certificate generation or management; the operator supplies and rotates certs.

agent_guidance: An agent calling a Synse deployment needs no credential and will not be told it lacks
  authority. The only thing standing between a caller and a write to physical hardware is network reach,
  so treat network placement, not an auth header, as the access control boundary.
