? Raw Log Data: When devices send logs to FortiSIEM, the data arrives in a raw, unstructured format.

? Data Parsing Process: The process that converts this raw log data into a structured format is known as data parsing.

Data Parsing: This involves extracting relevant fields from the raw log entries and organizing them into a structured format, making the data usable for analysis, reporting, and correlation.

? Significance of Structured Data: Structured data is essential for effective event correlation, alerting, and generating meaningful reports.

? References: FortiSIEM 6.3 User Guide, Data Parsing section, which details how raw log data is transformed into structured data through parsing.

? 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.

Clear Condition: This is typically a predefined condition that indicates the issue causing the incident has been resolved or no longer exists.

? 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."

? Monitor Column Indicators: In FortiSIEM, the Monitor column displays the status of various metrics applied during the discovery process.

? Yellow Star Meaning: A yellow star next to a metric indicates that the metric was successfully applied during discovery and data has been collected for that metric.

? Successful Data Collection: This visual indicator helps administrators quickly identify which metrics are active and have data available for analysis.

? References: FortiSIEM 6.3 User Guide, Device Monitoring section, which explains the significance of different icons and indicators in the Monitor column.

? Event Collection Overview: The exhibits show three events collected over a 10-minute period from two servers, Server A and Server B.

? Rule Subpattern Settings: The rule subpattern specifies two conditions:

AVG(CPU Util) > DeviceToCMDBAttr(Host IP : Server CPU Util Critical Threshold): This checks if the average CPU utilization exceeds the critical threshold defined for each server.

COUNT(Matched Events) >= 2: This requires at least two matching events within the specified period.

? Server A Analysis:

Events: Three events (CPU=90, CPU=90, CPU=95).

Average CPU Utilization: (90+90+95)/3 = 91.67, which exceeds the critical threshold of 90.

Matched Events Count: 3, which meets the condition of being greater than or equal to 2.

Incident Generation: Server A meets both conditions, so it generates one incident.

? Server B Analysis:

Events: Three events (CPU=70, CPU=50, CPU=60).

Average CPU Utilization: (70+50+60)/3 = 60, which does not exceed the critical threshold of 90.

Matched Events Count: 3, but since the average CPU utilization condition is not met, no incident is generated.

? Conclusion: Based on the rule subpattern, Server A will generate one incident, and Server B will not generate any incidents.

? References: FortiSIEM 6.3 User Guide, Event Correlation Rules and Incident Management sections, which explain how incidents are generated based on rule subpatterns and event conditions.

? FortiSIEM Architecture: In FortiSIEM, collectors gather data from various sources and send this data to supervisors and workers within the FortiSIEM architecture.

? Communication Requirements: For collectors to effectively send data to the FortiSIEM system, specific communication channels must be open.

? Port Usage: The primary port used for secure communication between the collectors and the FortiSIEM infrastructure is HTTPS (port 443).

? Network Configuration: When configuring collectors in geographically separated sites, the HTTPS port must be open for the collectors to communicate with both the supervisor and the worker upload settings addresses. This ensures that the collected data can be securely transmitted to the appropriate processing and analysis components.
