An administrator defines SMTP as a critical process on a Linux server. If the SMTP process is stopped, FortiSIEM would generate a critical event with which event type?
Correct Answer:
A
What operating system is FortiSIEM based on?
Correct Answer:
A
Refer to the exhibit.
An administrator is trying to identify an issue using an expression bated on the Expression Builder settings shown in the exhibit however, the error message shown in the exhibit indicates that the expression is invalid.
Which is the correct expression?
Correct 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.
References: FortiSIEM 6.3 User Guide, Expression Builder section, which explains the correct syntax and usage for creating valid expressions for event analysis.
What does the Frequency field determine on a rule?
Correct Answer:
A
Rule Evaluation in FortiSIEM: Rules in FortiSIEM are evaluated periodically to check if the defined conditions or subpatterns are met.
Frequency Field: The Frequency field in a rule determines the interval at which the rule's subpattern will be evaluated.
Evaluation Interval: This defines how often the system will check the incoming events against the rule's subpattern to determine if an incident should be triggered.
Impact on Performance: Setting an appropriate frequency is crucial to balance between timely detection of incidents and system performance.
Examples:
If the Frequency is set to 5 minutes, the rule will evaluate the subpattern every 5 minutes.
This means that every 5 minutes, the system will check if the conditions defined in the subpattern are met by the incoming events.
