If a hard disk on a FortiAnalyzer unit fails, it must be replaced. On FortiAnalyzer devices that support hardware RAID, the hard disk can be replaced while the unit is still running - known as hot swapping. On FortiAnalyzer units with software RAID, the device must be shutdown prior to exchanging the hard disk.

Events in FortiAnalyzer will be in one of four statuses. The current status will determine if more actions need to be taken by the security team or not.
The possible statuses are:
Unhandled: The security event risk is not mitigated or contained, so it is considered open.
Contained: The risk source is isolated.
Mitigated: The security risk is mitigated by being blocked or dropped.
(Blank): Other scenarios.

FortiAnalyzer_7.0_Study_Guide-Online.pdf page 217: Threat hunting consists in proactively searching for suspicious or potentially risky network activity in your environment. The proactive approach will help administrator find any threats that might have eluded detection by the current security solutions or configurations.

If the imported playbook has the same name as an existing one, FortiAnalyzer will create a new name that includes a timestamp to avoid conflicts.
Playbooks are imported with the same status they had (enabled or disabled) when they were exported.
Playbooks set to run automatically should be exported while they are disabled to avoid unintended runs on the destination.
