 Incident Status in FortiSIEM: The status of an incident indicates its current state and helps administrators track and manage incidents effectively.

 Cleared Status: When an incident’s status is "Cleared," it means that a specific condition set to clear the incident has been satisfied.

 Automatic vs. Manual Clearance: While some incidents may be cleared automatically based on clear conditions, others might be manually cleared by an operator.

 References: FortiSIEM 6.3 User Guide, Incident Management section, detailing the various incident statuses and the conditions that lead to an incident being marked as "Cleared."

 Incident Creation in FortiSIEM: Incidents in FortiSIEM are created based on specific patterns and conditions defined within the system.

 Group By Function: The "Group By" section in the "Edit SubPattern" window specifies how the data should be grouped for analysis and incident creation.

 Impact of Grouping: The way data is grouped affects the number of incidents generated. Each unique combination of the grouped attributes results in a separate incident.

 Exhibit Analysis: In the provided exhibit, the "Group By" section lists "Reporting Device," "Reporting IP," and "User." This means incidents will be created for each unique combination of these attributes.

 References: FortiSIEM 6.3 User Guide, Rule and Pattern Creation section, which details how grouping impacts incident generation.

 Grouping Attributes in Reports: When creating reports in FortiSIEM, certain attributes can be grouped to summarize and organize the data.

 Unique Attributes: Attributes that are unique for each event cannot be grouped because they do not provide a meaningful aggregation or summary.

 Red Highlighting Explanation: The red highlighting in the exhibit indicates attributes that cannot be grouped together due to their unique nature. These unique attributes includeEvent Receive Time,Reporting IP,Event Type,Raw Event Log, andCOUNT(Matched Events).

 Attribute Characteristics:

Event Receive Timeis unique for each event.

Reporting IPandEvent Typecan vary greatly, making grouping them impractical in this context.

Raw Event Logrepresents the unprocessed log data, which is also unique.

COUNT(Matched Events)is a calculated field, not suitable for grouping.

 References: FortiSIEM 6.3 User Guide, Reporting section, explains the constraints on grouping attributes in reports.
