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.

Enabling this option allows any user authenticated by the LDAP server to log in to FortiAnalyzer, effectively creating a wildcard administrator.

This allows FortiAnalyzer to correctly identify and process logs from different members of the HA cluster.

To prevent log modification or tampering: The set log-checksum command with options like md5 or sha1 calculates a checksum value for the log data. This checksum acts as a digital signature, allowing FortiAnalyzer to verify the integrity of the logs and detect any unauthorized modifications.

To protect log data from man-in-the-middle attacks: By using checksums, FortiAnalyzer can ensure that the logs received have not been altered in transit during a man-in-the-middle attack. If the checksum of the received logs doesn't match the expected value, it indicates potential tampering.

The two correct statements about high availability (HA) on FortiAnalyzer are:

FortiAnalyzer HA supports synchronization of logs as well as some system and configuration settings.

FortiAnalyzer HA synchronizes both logs and certain system configuration settings between the units in the cluster to ensure consistent operation.

All devices in a FortiAnalyzer HA cluster must run in the same operation mode, either analyzer mode or collector mode.

In an HA cluster, all devices must be configured to operat` e in the same mode — either analyzer mode or collector mode—to ensure consistency and proper functionality across the cluster.

The other options, such as VRRP, are not required for HA in FortiAnalyzer, and disk space can vary between nodes but may impact log storage capacity.

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.

When upgrading firmware on an HA cluster of FortiAnalyzer devices, it is recommended to upgrade the secondary devices first, and then upgrade the primary device to minimize downtime and maintain continuity in log collection and other HA functions. This ensures that the primary device continues to handle operations while the secondary devices are being upgraded, and once the secondary devices are updated, the primary device can be upgraded with minimal service disruption.
