SPLK-1002 Advanced Searching and Statistics Practice Question
A security analyst wants to find IP addresses that have been involved in both login failures and successful logins within a 5-minute window. Which approach is most efficient?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Using the transaction command
Using the transaction command. The transaction command groups events from the same IP address (or other field) within a specified time window, such as 5 minutes, making it ideal for correlating login failures and successes from the same source. Option B (appendcols) is inefficient because it requires manual field matching and does not handle time windows. Option C (subsearch) is resource-intensive and not designed for event correlation across time. Option D (stats with values) can aggregate fields but cannot guarantee temporal proximity between events. Thus, transaction is the most efficient and appropriate command for this scenario.

- ✓
Using the transaction command
Why this is correct
Groups events by IP within a time span, ideal for this scenario.
- ✗
Using the appendcols command
Why it's wrong here
Requires exact field matching and does not handle time correlation.
- ✗
Using a subsearch
Why it's wrong here
Subsearches are inefficient and not designed for time-window correlation.
- ✗
Using the stats command with values
Why it's wrong here
Does not ensure events are within a time window.
