# All Envoy extensions must be tagged with their security hardening stance with
# respect to downstream and upstream data plane threats. These are verbose
# labels intended to make clear the trust that operators may place in
# extensions.
security_postures:
- name: robust_to_untrusted_downstream
  description: |
    This extension is intended to be robust against untrusted downstream traffic. It
    assumes that the upstream is trusted.
- name: robust_to_untrusted_downstream_and_upstream
  description: |
    This extension is intended to be robust against both untrusted downstream and
    upstream traffic.
- name: requires_trusted_downstream_and_upstream
  description: |
    This extension is not hardened and should only be used in deployments
    where both the downstream and upstream are trusted.
- name: unknown
  # This is functionally equivalent to
  # requires_trusted_downstream_and_upstream, but acts as a placeholder to
  # allow us to identify extensions that need classifying.
  description: |
    This extension has an unknown security posture and should only be
    used in deployments where both the downstream and upstream are
    trusted.
- name: data_plane_agnostic
  # Not relevant to data plane threats, e.g. stats sinks.
  description: |
    This extension does not operate on the data plane and hence is intended to be robust against untrusted traffic.

status_values:
- name: stable
  # This extension is stable and is expected to be production usable.
  description:
- name: alpha
  description: |
    This extension is functional but has not had substantial production burn time,
    use only with this caveat.
- name: wip
  description: |
    This extension is work-in-progress. Functionality is incomplete and it is not intended for production use.
