SecurityPolicies

  • Warning: If a SecurityPolicy contains a HTTPRoute targetRef which doesn't exist, the policy is still accepted but will not apply without warning.
  • How to combine IP Allowlist and Basic Authentication?
    • "Envoy Gateway delegates auth to Envoy filters: Basic Auth and IP allowlisting (via RBAC) are separate. You can get an AND by applying both (e.g., a SecurityPolicy that includes Basic Auth plus IP-based authorization). A true OR (“allow if IP is allowed OR creds are valid”) isn’t supported today without custom ext_authz logic."
  • Bypass http basic auth for some ip addresses
