10 SOC Analyst Interview Questions You'll Actually Be Asked

SOC interviews don't test memorization — they test how you think. Here are ten questions that come up constantly, with what interviewers are really listening for.

1. Explain the CIA triad

Confidentiality, Integrity, Availability. Keep it crisp and give one real example for each.

2. What's the difference between IDS and IPS?

Detection vs. prevention. Bonus points for noting where each sits in the network.

3. You see 500 failed logins from one IP. What do you do?

Walk through triage: verify scope, check if any succeeded, block or escalate per playbook, document.

4. Explain the TCP three-way handshake

SYN, SYN-ACK, ACK — and why it matters (think SYN floods).

5. You find malware on a workstation. Now what?

Contain first (isolate the host), then investigate, then remediate. Order matters.

6. What is a SIEM and how have you used one?

Be honest about your level. Lab experience counts — describe what you actually did.

7. How would you analyze a suspicious email?

Headers first, then links and attachments in a safe environment, then IOCs and verdict.

8. What are ports 80, 443, 22, and 3389?

HTTP, HTTPS, SSH, RDP. Know the common ones cold.

9. How do you prioritize 50 alerts at once?

Severity, asset criticality, and exploitability. Show a framework, not panic.

10. Tell me about a lab or project you've done

This is where a portfolio wins interviews. Have 2–3 projects you can walk through confidently.

practice answers out loud, not just in your head. Interviews reward clear communicators.
