Rule Evaluation in FortiSIEM: Rules in FortiSIEM are evaluated periodically to check if the defined conditions or subpatterns are met.

Frequency Field: The Frequency field in a rule determines the interval at which the rule's subpattern will be evaluated.

Evaluation Interval: This defines how often the system will check the incoming events against the rule's subpattern to determine if an incident should be triggered.

Impact on Performance: Setting an appropriate frequency is crucial to balance between timely detection of incidents and system performance.

Examples:

If the Frequency is set to 5 minutes, the rule will evaluate the subpattern every 5 minutes.

This means that every 5 minutes, the system will check if the conditions defined in the subpattern are met by the incoming events.

Reference: FortiSIEM 6.3 User Guide, Rules and Incidents section, which explains the Frequency field and how it impacts the evaluation of subpatterns in rules.

Collecting SIEM and PAM Events: To collect both SIEM event logs and Performance and Availability Monitoring (PAM) events from a Microsoft Windows server, a suitable protocol must be selected.

WMI Protocol: Windows Management Instrumentation (WMI) is the appropriate protocol for this task.

SIEM Event Logs: WMI can collect security, application, and system logs from Windows devices.

PAM Events: WMI can also gather performance metrics, such as CPU usage, memory utilization, and disk activity.

Comprehensive Data Collection: Using WMI ensures that both types of data are collected efficiently from the Windows server.

Reference: FortiSIEM 6.3 User Guide, Data Collection Methods section, which details the use of WMI for collecting various types of logs and performance metrics.

FortiSIEM Architecture: The FortiSIEM architecture includes several components such as Supervisors, Workers, Collectors, and Agents, each playing a distinct role in the SIEM ecosystem.

Real-Time Event Correlation: Real-time event correlation is a critical function that involves analyzing and correlating incoming events to detect patterns indicative of security incidents or operational issues.

Role of Supervisor and Worker:

Supervisor: The Supervisor oversees the entire FortiSIEM system, coordinating the processing and analysis of events.

Worker: Workers are responsible for processing and correlating the events received from Collectors and Agents.

Collaboration for Correlation: Together, the Supervisor and Worker components perform real-time event correlation by distributing the load and ensuring efficient processing of events to identify incidents in real-time.

Reference: FortiSIEM 6.3 User Guide, Event Correlation and Processing section, details how the Supervisor and Worker components collaborate for real-time event correlation.

Grouping Events in FortiSIEM: Grouping events by specific attributes allows administrators to aggregate and analyze data more efficiently.

Grouping Criteria: In this case, the events are grouped by 'Event Type' and 'User' attributes.

Unique Combinations: To determine the number of results displayed, identify the unique combinations of the 'Event Type' and 'User' attributes in the provided data.

Failed Logon by Ryan (appears multiple times but is one unique combination)

Failed Logon by John

Failed Logon by Paul

Failed Logon by Wendy

Unique Groupings: There are four unique groupings based on the given data: 'Failed Logon' by 'Ryan', 'John', 'Paul', and 'Wendy'.

Reference: FortiSIEM 6.3 User Guide, Event Management and Reporting sections, which explain how events are grouped and reported based on selected attributes.

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.
