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.

Case Sensitivity in Searches: In FortiSIEM, search queries, including those for raw event logs, are case sensitive. This means that keywords must be entered exactly as they appear in the logs.
Keyword Mismatch: The exhibit shows the keyword "TCP" in the Value field. If the actual events use "tcp" (lowercase), the search will return no results because of the case mismatch.
Correct Keyword: To match the keyword correctly, the administrator should enter "tcp" in the Value field.
References: FortiSIEM 6.3 User Guide, Search and Filtering section, which discusses the importance of case sensitivity in search queries.

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.

Anomaly Baseline Data: Anomaly baseline data refers to the statistical profiles and baselines calculated for various parameters to detect deviations indicative of potential security incidents.
Profile DB: The Profile DB is specifically designed to store such baseline data in FortiSIEM.
* Purpose: It maintains statistical profiles for different monitored parameters to facilitate anomaly detection.
* Usage: This data is used by FortiSIEM to compare real-time metrics against the established baselines to identify anomalies.
