What protocol does FortiGate use to send encrypted logs to FortiAnalyzer (FAZ)?

FortiGate uses the OFTPS protocol for securely sending encrypted logs to FortiAnalyzer. OFTPS, which stands for Fortinet's optimized FTP with Transport Layer Security, ensures that log data is encrypted during transmission, providing a layer of security for logs that may contain sensitive information. This is particularly important in network security, as ensuring the confidentiality and integrity of log data helps prevent unauthorized access and tampering.

In contrast, traditional FTP does not encrypt data and leaves logs vulnerable to interception, while HTTPS is primarily designed for web traffic and not specifically tailored for the purposes of log transfer between Fortinet devices. OFPTP, on the other hand, is not a recognized standard protocol for log transmission in the Fortinet ecosystem. Hence, OFTPS is the correct protocol used in this context.
