A sub-pattern for a rule in FortiSIEM is defined by which of the following?

A sub-pattern for a rule in FortiSIEM is defined by filters, aggregation, and group by definitions. This configuration allows users to specify criteria for the data they are interested in monitoring and analyzing within the system.

Filters play a crucial role in refining the data set to focus on specific events or logs that meet certain criteria. This is important for identifying relevant patterns and anomalies effectively. Aggregation allows the system to combine multiple data points, which is essential for summarizing information over a defined period or within a particular context. The "group by" definitions are used to categorize the data into meaningful groups, making it easier to analyze trends or take action based on specific segments of the data.

The other options, while they contain relevant components, do not encompass the full scope required for defining a sub-pattern in FortiSIEM. For example, conditions and actions focus more on decision-making processes rather than the foundational aspect of identifying patterns in the data. Conversely, time window definitions and thresholds are important in other contexts but do not specifically describe the components of a sub-pattern as effectively as filters, aggregation, and group by definitions.
