What are key elements of a well-constructed notable event? (Choose three)
A notable event in Splunk Enterprise Security (ES) represents a significant security detection that requires investigation.
Key Elements of a Good Notable Event: Meaningful Descriptions (Answer A)
Helps analysts understand the event at a glance.
Example: Instead of 'Possible attack detected,' use 'Multiple failed admin logins from foreign IP address'.
Proper Categorization (Answer C)
Ensures events are classified correctly (e.g., Brute Force, Insider Threat, Malware Activity).
Example: A malicious file download alert should be categorized as 'Malware Infection', not just 'General Alert'.
Relevant Field Extractions (Answer D)
Ensures that critical details (IP, user, timestamp) are present for SOC analysis.
Example: If an alert reports failed logins, extracted fields should include username, source IP, and login method.
Why Not the Other Options?
B. Minimal use of contextual data -- More context helps SOC analysts investigate faster.
