What two steps are required to visualize API connectivity and enable API protection in VMware...

To visualize API connectivity and enable API protection in VMware Tanzu Service Mesh, the administrator needs to perform two steps:

Activate API Discovery for the Global Namespace. This allows Tanzu Service Mesh to automatically discover the APIs signatures between microservices running inside or outside the mesh. API Discovery creates a custom API schema for each API that is close to OpenAPI spec 3.0. Tanzu Service Mesh graph renders the detected APIs in the Enforcing mode by default, which means that any new API is considered as a violated API unless accepted by the administrator1

Create API Security Policy for the Global Namespace. This allows the administrator to block or allow layer 4 and layer 7 traffic, as well as create granular policies that provide API and data segmentation, OWASP 10 attack defense, schema validation, geofencing, data compliance, and egress controls. The administrator can create the API Security policy through the Tanzu Service Mesh Console UI or by using the Tanzu Service Mesh API Explorer2
