Security Posture

Review the following information about security posture of Solo’s Gloo Edge Envoy extensions. For more information, see the Envoy threat model.

About the security posture

The security posture includes extensions for both the Open Source and Enterprise versions of Gloo Edge. Each extension has the filter name and the the classification of the filter’s security posture. The following table describes the security posture values.

Value Description
data_plane_agnostic Do not expose this extension to data plane attacks, for both untrusted downstreams and upstream services.
requires_trusted_downstream_and_upstream Use this extension only when both the downstream and upstream services are trusted.
robust_to_untrusted_downstream You can use these hardened filters only with untrusted downstream services. Do not use with untrusted upstream services, as these filters assume that the upstream services are trusted.
robust_to_untrusted_downstream_and_upstream You can use these hardened filters with both untrusted downstream and upstream services.
unknown Use these filters with your own security procedures. These filters have an unknown security posture.
