To combine multiple events or conditions to identify suspicious activity

To generate reports for compliance and management review

To collect raw logs from various sources and store them centrally

To block malicious traffic at the firewall

What is the purpose of validating a correlation rule against known attack scenarios?

To determine the cost of the SIEM platform

A SOC analyst has written a correlation rule to detect 'account lockout followed by a successful login from a different IP'. Before deploying the rule to production, the analyst wants to validate it. Which validation approach is most appropriate?

Run the rule against a synthetic dataset that contains only normal login activity.

Replay historical logs from a known account-lockout incident and verify the rule triggers.

Deploy the rule directly to production and monitor for alerts over a week.

Ask another analyst to review the rule logic without executing it.

Which method is commonly used to validate a correlation rule?

Deleting all logs and starting fresh

Asking the SIEM vendor for a refund

Replaying historical log data that contains the attack pattern

Increasing the rule's priority to critical

What is the purpose of documenting a security use case?

To provide a reference for SOC analysts to understand the detection logic and intent

To satisfy the requirement for a paper trail for auditors only

To increase the complexity of the SIEM configuration

To replace the need for analyst training
