Anomaly Data Storage: Anomaly data, including running averages and standard deviation values for different parameters such as traffic and device resource usage, is stored in a specific database.

Profile DB: The Profile DB is used to store this type of anomaly data.

Function: It maintains statistical profiles and baselines for monitored parameters, which are used to detect anomalies and deviations from normal behavior.

Significance: Storing anomaly data in the Profile DB allows FortiSIEM to perform advanced analytics and alerting based on deviations from established baselines.

Reference: FortiSIEM 6.3 User Guide, Database Architecture section, which describes the purpose and contents of the Profile DB in storing anomaly and baseline data.

Enterprise Licensing Mode: In FortiSIEM enterprise licensing mode, collectors are deployed in remote sites to gather and forward data to the central FortiSIEM cluster located in the data center.

Collector Functionality: Collectors are responsible for receiving logs, events (e.g., syslog), and performance metrics from devices.

Link Down Scenario: When the link between the collector and the FortiSIEM cluster is down, the collector needs a mechanism to ensure no data is lost during the disconnection.

Event Buffering: The collector buffers the events locally until the connection is restored, ensuring that no incoming events are lost. This buffered data is then forwarded to the FortiSIEM cluster once the link is re-established.

Reference: FortiSIEM 6.3 User Guide, Data Collection and Buffering section, explains the behavior of collectors during network disruptions.

Performance and Availability Monitoring: Various components in FortiSIEM are responsible for monitoring the performance and availability of devices and services.

Components:

Supervisor: Oversees the entire FortiSIEM infrastructure and coordinates the activities of other components.

Worker: Processes and analyzes the collected data, including performance and availability metrics.

Collector: Gathers performance and availability data from devices in the network.

Collaborative Functioning: These components work together to ensure comprehensive monitoring of the network's performance and availability.

Reference: FortiSIEM 6.3 User Guide, Performance and Availability Monitoring section, which explains the roles of the supervisor, worker, and collector in monitoring tasks.

Feature Overview: FortiSIEM provides several tools for querying and reporting on device information within an environment.

Inventory Tab: The Inventory tab is specifically designed to display detailed information about devices, including their firmware versions.

Query Functionality: Within the Inventory tab, you can run queries to filter and display devices based on specific attributes, such as the firmware version for FortiGate devices.

Report Generation: By running a query in the Inventory tab, you can produce a report that lists the FortiGate devices and their corresponding firmware versions.

Reference: FortiSIEM 6.3 User Guide, Inventory Management section, explains how to use the Inventory tab to query and report on device attributes.

Discovery Methods in FortiSIEM: FortiSIEM can discover devices using various methods, including syslog, SNMP, and others.

Syslog Discovery: The exhibit shows that the FortiGate device is discovered by FortiSIEM using syslog.

Syslog Parsing: The syslog messages sent by the FortiGate device are parsed by FortiSIEM to extract relevant information.

CMDB Entry: Based on the parsed information, an entry is populated in the Configuration Management Database (CMDB) for the device.

Evidence in Exhibit: The exhibit shows the syslog flow from the FortiGate Firewall to the parsing and discovery process, resulting in the device being listed in the CMDB with the status 'Pending.'

Reference: FortiSIEM 6.3 User Guide, Device Discovery section, which explains how syslog discovery works and how devices are added to the CMDB based on syslog data.
