When is the OFTPS protocol used to secure log communication?

The OFTPS protocol is utilized to secure log communication automatically negotiated based on the connecting FortiGate device. This means that the FortiAnalyzer can dynamically determine which encryption method to use based on its communication with the FortiGate, ensuring optimal security measures are in place without requiring manual configuration each time.

This automatic negotiation is beneficial in maintaining secure log transmission, as it allows for adaptability based on the FortiGate's capabilities and configurations. It helps in establishing a secure channel as needed, facilitating seamless integration and communication between devices.

In contrast, other options suggest scenarios that either impose limitations or misrepresent the behavior of OFTPS in relation to FortiAnalyzers and FortiGates. This option captures the essence of how OFTPS is designed to work within the Fortinet ecosystem effectively and securely.
