In the deployment scenario described, where an NGINX container is listening on port 8080 and mapped to host port 80, the Cloud Native Application Firewall (CNAF) rule should specify host port 80 (option B) to protect the application. This is because the external traffic directed towards the containerized application will be accessing it through the host port 80, which is the exposed port to the outside network. Specifying port 80 in the CNAF rule ensures that the firewall can inspect and protect the incoming traffic to the application effectively.

When authenticating the Prisma Cloud plugin in the IntelliJ application, the mandatory fields are the Secret Key, Prisma Cloud API URL, and Access Key. These credentials are required to securely authenticate and enable the plugin to communicate with the Prisma Cloud API, ensuring that the plugin can perform its intended functions within the development environment.
