You can select one or more of the following authentication methods for a security policy:
You define and assign security policies when you create APIs and operations. You can use an existing security policy or create a new security policy. When you deploy an API, you can override the policies that are assigned to it.
The API References area of an authentication policy displays all the designed APIs that use the policy.
