Question
How can you incorporate additional context into notable events generated by correlation searches?
A. By adding enriched fields during search execution
B. By using the dedup command in SPL
C. By configuring additional indexers
D. By optimizing the search head memory
Answer
A. By adding enriched fields during search execution
Explanation
In Splunk Enterprise Security (ES), notable events are generated by correlation searches that identify patterns or anomalies in data. Adding additional context to these events is critical for effective incident investigation and response. Here’s how adding enriched fields during search execution helps achieve this:
Enriched Fields in Correlation Searches
Enriched fields provide additional metadata or context to notable events, such as user details, asset information, threat intelligence, or network data. These fields are typically derived from external sources like asset and identity lookups, threat intelligence feeds, or other indexed data.
To include these fields, you must ensure they are part of the correlation search’s results set. This involves:
- Defining the desired fields in the correlation search query.
- Using Splunk macros like get_asset or get_identity to pull relevant data from lookup tables or other indexes.
Benefits of Adding Context
Improved Investigations: Analysts can quickly understand the scope and impact of an event without running additional queries.
Actionable Insights: Enriched fields help prioritize incidents by providing critical details such as asset importance or user risk level.
Streamlined Incident Review: Relevant fields are displayed in the Incident Review dashboard, making it easier for analysts to assess and act on notable events.
Implementation Steps
To incorporate enriched fields:
- Edit the correlation search via Content Management in Splunk ES.
- Modify the search query to include enrichment commands (e.g., | lookup or | eval).
- Ensure that the enriched fields are part of the final output by using commands like table or fields.
- Save and enable the correlation search. The enriched fields will now appear in newly generated notable events.
Why Other Options Are Incorrect
B. Using the dedup command in SPL: This command is used for removing duplicate results in a search and does not add context to notable events.
C. Configuring additional indexers: Indexers manage data storage and retrieval but do not directly impact the context of notable events.
D. Optimizing the search head memory: While important for performance, this does not enrich notable event data.
By incorporating enriched fields during search execution, you enhance the quality and utility of notable events, aligning with best practices for detection engineering in Splunk ES.
