Special Notices

This section highlights some of the operational changes that administrators should be aware of in FortiAnalyzer version 6.2.7.

Newly deployed, factory reset, or disk format may trigger upgrade code on subsequent reboot

For a newly deployed VM instance or appliance, a disk format or a factory reset on a FortiAnalyzer unit running version 6.2.3 may trigger the upgrade code upon rebooting the system, which in turn may update the database configuration, although no upgrades are required. This issue does not affect FortiAnalyzer units upgraded from versions prior to 6.2.3.

Workaround: Immediately after deploying a new FortiAnalyzer with version 6.2.3, reboot the system before administering any configuration.

Maximum ADOM limits for FortiAnalyzer

FortiAnalyzer hardware devices and VMs display a warning when the recommended maximum number of ADOMs is reached or exceeded. The platform does not enforce the limit; however, adding more ADOMs may affect the performance of the unit. For more details, see Appendix A - Recommended maximum number of ADOMs supported.

Port 8443 reserved

Port 8443 is reserved for https-logging from FortiClient EMS for Chromebooks.

All OFTP connections must be encrypted for FortiAnalyzer 6.2.0 (or higher)

Prior to upgrading to FortiAnalyzer 6.2, make sure that all FortiGate devices are configured to use encryption when communicating with FortiAnalyzer. Starting with FortiAnalyzer 6.2.0, all OFTP communications must be encrypted.

Hyper-V FortiAnalyzer-VM running on an AMD CPU

A Hyper-V FAZ-VM running on a PC with an AMD CPU may experience a kernel panic. Fortinet recommends running VMs on an Intel-based PC.

SSLv3 on FortiAnalyzer-VM64-AWS

Due to known vulnerabilities in the SSLv3 protocol, FortiAnalyzer-VM64-AWS only enables TLSv1 by default. All other models enable both TLSv1 and SSLv3. If you wish to disable SSLv3 support, please run:

config system global

set ssl-protocol t1sv1

end

Pre-processing logic of ebtime

Logs with the following conditions met are considered usable for the calculation of estimated browsing time:

Traffic logs with logid of 13 or 2, when logid == 13, hostname must not be empty. The service field should be either HTTP, 80/TCP or 443/TCP.

If all above conditions are met, then devid, vdom, and user (srcip if user is empty) are combined as a key to identify a user. For time estimation, the current value of duration is calculated against history session start and end time, only un-overlapped part are used as the ebtime of the current log.
