Question on Mixer support in Istio 1.5 and authorization policy

Security
1

Hello,

I have the following questions:-

  1. We are currently using Istio 1.4 and we have a mixer configuration model in which we invoke a Adapter. Adapter in turn makes a rest call to determine if authorization is allowed or not for the user in the request.

With mixer being deprecated in Istio 1.5, How do we perform the authorization check using a rest call?

  1. Regarding authorization policies at https://istio.io/docs/reference/config/security/authorization-policy/#Operation, Is there a regular expression match available to match the path? For e.g
    paths: ["/data/[0-9]+/types"]

Please clarify
Thanks,
Shruthi
