What is the default setting for securing log communication between FAZ and Fortigate?

The default setting for securing log communication between FortiAnalyzer (FAZ) and FortiGate is OFTPS, which stands for "Over-the-Top FTP Secure." OFTPS is a protocol that enhances the standard FTP by adding a layer of security through encryption, allowing for secure communication while transferring logs between the devices.

This method ensures that the logs are securely sent over the internet or within the network, protecting them from eavesdropping and tampering. It is specifically designed to work with FortiGate and FortiAnalyzer deployments, ensuring compatibility and ease of use while maintaining security.

While the other options, such as FTPS, SFTP, and OFTP, are secure file transfer protocols, they do not specifically refer to the default setting that Fortinet chose for securing log communication in this context. Therefore, OFTPS is the correct answer as it is tailored for the Fortinet ecosystem.
