How is a subparttern for a rule defined?

  1. Filters Aggregation. Group By definition
  2. Filters Group By definitions. Threshold
  3. Filters Threshold Time Window definitions
  4. Filters Aggregation Time Window definitions

Answer(s): D

Explanation:

Rule Subpattern Definition: In FortiSIEM, a subpattern within a rule is used to define specific conditions and criteria that must be met for the rule to trigger an incident or alert. Components of a Subpattern: The subpattern includes the following elements:
Filters: Criteria to filter the events that the rule will evaluate. Aggregation: Conditions that define how events should be aggregated or grouped for analysis. Time Window Definitions: Specifies the time frame over which the events will be evaluated to determine if the rule conditions are met.

Together, these components allow the system to efficiently and accurately detect patterns of interest within the event data.


Reference:

FortiSIEM 6.3 User Guide, Rules and Patterns section, which explains the structure and configuration of rule subpatterns, including the use of filters, aggregation, and time window definitions.



Where do you configure rule notifications and automated remediation on FortiSIEM?

  1. Notification policy
  2. Remediation policy
  3. Notification engine
  4. Remediation engine

Answer(s): A

Explanation:

Rule Notifications and Automated Remediation: In FortiSIEM, notifications and automated remediation actions can be configured to respond to specific incidents or alerts generated by rules. Notification Policy: This is the section where administrators configure the settings for notifications and specify the actions to be taken when a rule triggers an alert. Configuration Options: Includes defining the recipients of notifications, the type of notifications (e.g., email, SMS), and any automated remediation actions that should be executed. Importance: Proper configuration of notification policies ensures timely alerts and automated responses to incidents, enhancing the effectiveness of the SIEM system.


Reference:

FortiSIEM 6.3 User Guide, Notifications and Automated Remediation section, which details how to configure notification policies for rule-triggered actions and responses.



What are the four categories of incidents?

  1. Devices, users, high risk, and low risk
  2. Performance, devices, high risk, and low risk
  3. Performance, availability, security, and change
  4. Security, change, high risk, and low risk

Answer(s): C

Explanation:

Incident Categories in FortiSIEM: Incidents in FortiSIEM are categorized to help administrators quickly identify and prioritize the type of issue.
Four Main Categories:
Performance: Incidents related to the performance of devices and applications, such as high CPU usage or memory utilization.
Availability: Incidents affecting the availability of services or devices, such as downtime or connectivity issues.
Security: Incidents related to security events, such as failed login attempts, malware detection, or unauthorized access.
Change: Incidents triggered by changes in the configuration or state of devices, such as new software installations or configuration modifications.
Importance of Categorization: These categories help in the efficient management and response to different types of incidents, allowing for better resource allocation and quicker resolution.


Reference:

FortiSIEM 6.3 User Guide, Incident Management section, which details the different categories of incidents and their significance.



Refer to the exhibit.



The FortiSIEM administrator is examining events for two devices to investigate an issue. However, the administrator is not getting any results from their search. Based on the selected filters shown in the exhibit, why is the search returning no results?

  1. Parenthesis are missing.
  2. The wrong boolean operator is selected in the Next column.
  3. The wrong option is selected in the Operator column.
  4. An invalid IP subnet is typed in the Value column.

Answer(s): B

Explanation:

Search Filters in FortiSIEM: When searching for events, the correct use of filters and logical operators is crucial to obtain accurate results.
Issue Analysis:
Selected Filters: The exhibit shows filters for two different Reporting IP addresses. Logical Operators: The use of "AND" between the two Reporting IP addresses implies that an event must match both IP addresses simultaneously, which is not possible for a single event. Correct Usage: To search for events from either of the two IP addresses, parentheses should be used to group conditions logically.
Corrected Filter: (Reporting IP = 192.168.1.1 OR Reporting IP = 172.16.10.3) would return events from either IP address.

FortiSIEM 6.3 User Guide, Search and Filters section, which explains the use of logical operators and the importance of parentheses in constructing effective search queries.
