Q1
Walk me through your process for triaging and prioritizing alerts in a SIEM platform. How do you determine which alerts require immediate investigation versus which can be batched or tuned?
Why they ask this:* They want to assess your understanding of alert management, noise reduction, and risk-based prioritization—core SOC functions that prevent alert fatigue and ensure critical threats are addressed first.
Q2
Explain the difference between signature-based and behavioral-based detection methods. Can you give an example of a threat each method would catch better than the other?
Why they ask this:* This tests your knowledge of detection fundamentals and whether you understand the strengths and limitations of different detection approaches used in modern SOCs.
Q3
You're analyzing a suspicious PowerShell command found in Windows event logs. Walk me through how you would investigate this, what artifacts you'd examine, and what tools you'd use to determine if it's malicious.
Why they ask this:* They're testing your ability to perform host-based investigation, understand Windows logging, recognize attack patterns, and use forensic techniques—all essential for mid-level analysts.
Q4
How do you approach tuning a detection rule that's generating too many false positives while maintaining detection capability for actual threats?
