What happens if there is a mismatch in encryption levels between FortiGate and FAZ?

When there is a mismatch in encryption levels between FortiGate and FortiAnalyzer (FAZ), the communication required for log transmission cannot occur effectively. This disparity results in the logs not being transmitted at all. The encryption mismatch creates a scenario where the two devices cannot agree on the security protocols needed for secure communication, thus preventing any logs from being sent from the FortiGate to the FortiAnalyzer.

In secure communication systems like those used by Fortinet products, proper encryption alignment is crucial for establishing a secure connection. When encryption levels differ, it compromises the integrity and confidentiality of the data being transmitted. Therefore, the FortiGate will reject attempts to send logs until the encryption levels are compatible, which is why logs will not be transmitted in such a scenario.
