The default operating mode for FortiAnalyzer is analyzer mode. In this mode, FortiAnalyzer provides full functionality for event management and reporting features. This mode is intended for environments where comprehensive analysis and reporting are required. It allows FortiAnalyzer to collect, analyze, and store logs, as well as generate reports and manage events. References: FortiAnalyzer 7.4.1 Administration Guide, "Operating modes" section.

When you move a registered logging device from one ADOM (Administrative Domain) to another in FortiAnalyzer, it's essential to ensure that the analytical logs for the moved device are available in the new ADOM to maintain continuity in reporting and log analysis. The command execute sql-local rebuild-adom < new-ADOM-name > is used specifically for this purpose. Running this command populates the new ADOM with the analytical logs of the moved device, enabling you to generate accurate and comprehensive reports based on the historical data of the device in its new ADOM context. This process ensures that the transition of devices between ADOMs does not lead to a loss of analytical insight or reporting capabilities for the device's traffic and events.

To restrict administrative access on FortiAnalyzer, two effective methods are using administrator profiles and configuring trusted hosts. Administrator profiles allow for defining the level of access and permissions for different administrators, controlling what each administrator can see and do within the FortiAnalyzer unit. Configuring trusted hosts enhances security by limiting administrative access to specified IP addresses, ensuring that administrators can only connect from approved locations or networks, thus preventing unauthorized access from outside specified subnets or IP addresses.

In systems that support hardware RAID, hot swapping allows for the replacement of a failed disk without shutting down the system. This capability is crucial for maintaining uptime and ensuring data redundancy and availability, especially in critical environments. The RAID controller rebuilds the data on the new disk using redundancy data from the other disks in the array, ensuring no data loss and minimal impact on system performance.

In the context of a FortiAnalyzer unit equipped with hardware RAID support, the optimal approach to addressing a hard disk failure is to perform a hot swap of the disk. Hardware RAID configurations are designed to provide redundancy and fault tolerance, allowing for the replacement of a failed disk without the need to shut down the system. Hot swapping enables the administrator to replace the faulty disk with a new one while the system is still running, and the RAID controller will rebuild the data on the new disk, restoring the RAID array to its fully operational state.

Link aggregation is a method used to combine multiple network connections in parallel to increase throughput and provide redundancy in case one of the links fail. This feature is used in network appliances, including FortiAnalyzer, to add redundancy to the network connections, ensuring that there is a backup path for traffic if the primary path becomes unavailable. References: The FortiAnalyzer 7.4.1 Administration Guide explains the concept of link aggregation and its relevance to

To send reports from FortiAnalyzer to an external server, you must configure the output profile. This involves specifying the method (FTP, SFTP, or SCP), server IP, username, password, and the directory where the report will be saved. Additionally, you have the option to delete the report after it has been uploaded to the server.
