Answer : C, D, E

Advanced Analytical Rules Engine: FortiSIEM's rules engine allows for complex event correlation using multiple subpatterns.

Operations for Referencing Subpatterns:

FOLLOWED_BY: This operation is used to indicate that one event follows another within a specified time window.

OR: This logical operation allows for the inclusion of multiple subpatterns, where the rule triggers if any of the subpatterns match.

AND: This logical operation requires all referenced subpatterns to match for the rule to trigger.

Usage: These operations allow for detailed and precise event correlation, helping to detect complex patterns and incidents.

Reference: FortiSIEM 6.3 User Guide, Advanced Analytics Rules Engine section, which explains the use of different operations to reference subpatterns in rules.

Answer : C

Expression Builder in FortiSIEM: The Expression Builder is used to create expressions for analyzing event data.

Correct Syntax: The correct syntax for counting matched events is COUNT(Matched Events).

Function: COUNT is a function that takes a parameter, in this case, 'Matched Events,' to count the number of occurrences.

Common Errors: Incorrect syntax, such as reversing the order or using parentheses improperly, can lead to invalid expressions.

Reference: FortiSIEM 6.3 User Guide, Expression Builder section, which explains the correct syntax and usage for creating valid expressions for event analysis.

Answer : D

Device Discovery in FortiSIEM: Device discovery is the process by which FortiSIEM identifies and adds devices to its management scope.

Role of Collectors: Collectors are responsible for gathering data from network devices, including discovering new devices in the network.

Functionality: Collectors use protocols such as SNMP, WMI, and others to discover devices and gather their details.

Capability: While agents (Windows and Linux) primarily gather data from their host systems, the collectors actively discover devices across the network.

Reference: FortiSIEM 6.3 User Guide, Device Discovery section, which details the role of collectors in discovering network devices.

Answer : A

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.

Reference: FortiSIEM 6.3 User Guide, Search and Filtering section, which discusses the importance of case sensitivity in search queries.

Answer : B

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.

Reference: 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.'
