What does the "Idle" enforcement mode signify?

The "Idle" enforcement mode signifies that the Virtual Enforcement Node (VEN) is installed and operational, but it is not actively enforcing any security rules at that moment. This allows administrators to have the VEN actively deployed in the environment without applying any restrictions or rules that would limit traffic or communications within the network. It can be particularly useful for testing deployments or monitoring traffic patterns before moving to an enforcement mode that applies stricter controls.

In this context, the other options do not accurately describe the "Idle" mode. For example, removing all rules would imply a lack of configuration, and enforcing all rules would mean the VEN is actively blocking or allowing traffic based on those rules. Deleting its software suggests an uninstallation process rather than simply being idle. Thus, "Idle" clearly corresponds to the scenario where the VEN is present but not applying rules, allowing for future adjustments or testing without immediate impact on network traffic.
