 ## Security
 
-IPDK uses underlying gRPC communication between clients (p4rt-ctl & gnmi-ctl) and server
-on InfraP4d for:
-  - Creating ports.
-  - Settingup pipeline.
-  - Configuring forwarding rules.
-By default this gRPC communication is secure, user has option to use in-secure mode too

-IPDK has in-built script `generate-certs.sh` to generate certificates and copy to a specific
-location which will be used by gRPC Server and Client for secure communication.
