Getting hired as a SOC (Security Operations Center) Analyst requires both technical knowledge and the ability to think like an attacker. This guide covers 50 real interview questions asked by TCS, Wipro, Infosys, Accenture, and product companies in 2026, with detailed answers.
Basic SOC Analyst Interview Questions">SOC Analyst Questions
1. What is a SOC and what does it do?
A Security Operations Center (SOC) is a centralized unit that monitors, detects, analyzes, and responds to cybersecurity incidents 24/7. SOC analysts use SIEM tools, threat intelligence, and incident response playbooks to protect the organization.
2. What is the difference between SIEM and SOC?
SIEM (Security Information and Event Management) is a tool that collects and analyzes log data. SOC is a team that uses SIEM and other tools to monitor and respond to threats. Think of SIEM as the weapon and SOC as the soldier.
3. What is the CIA triad?
Confidentiality, Integrity, Availability — the three pillars of information security. Every security control maps to one or more of these principles.
4. What is a false positive in security monitoring?
A false positive occurs when a security tool flags benign activity as malicious. Reducing false positives is critical for SOC efficiency to prevent alert fatigue.
5. What is the difference between IDS and IPS?
IDS (Intrusion Detection System) only detects and alerts on threats. IPS (Intrusion Prevention System) can actively block detected threats inline.
Technical Questions
6. How would you investigate a phishing email?
Steps: (1) Check sender address and domain legitimacy, (2) Analyze headers for spoofing, (3) Check URLs without clicking (use URLScan or VirusTotal), (4) Check attachments in sandbox, (5) Search SIEM for other recipients, (6) Block indicators, (7) Report to incident response team.
7. What is the difference between TCP and UDP from a security perspective?
TCP is connection-oriented with guaranteed delivery, making it easier to track and filter. UDP is connectionless, faster, but harder to filter and commonly used in DDoS attacks and DNS amplification.
8. Explain the incident response lifecycle.
NIST framework: (1) Preparation, (2) Detection & Analysis, (3) Containment, (4) Eradication, (5) Recovery, (6) Lessons Learned. Each phase has specific playbooks and tools.
9. What logs would you check during an investigation?
Depends on the incident type, but common sources: Windows Event Logs, firewall logs, VPN logs, endpoint detection logs, DNS logs, proxy logs, SIEM alerts.
10. How do you prioritize alerts in a SOC?
Factors: severity level from SIEM, affected asset criticality, user privilege level, threat intelligence correlation, number of affected systems, and business impact.
SIEM Tool Questions
11. What SIEM tools have you worked with?
Common answers: Splunk, Microsoft Sentinel, QRadar, ArcSight, LogRhythm, Sumo Logic. Be specific about use cases: log parsing, correlation rules, dashboard creation.
12. How do you create a correlation rule in Splunk?
Example: index=firewall action=blocked src_ip=* | stats count by src_ip | where count > 100 — detects potential port scan by counting blocked connections per IP.
13. What is the MITRE ATT&CK framework?
A knowledge base of adversary tactics and techniques. SOC teams use it to map detected threats to known attacker behaviors, prioritize detection coverage, and create threat-informed defenses.
Scenario-Based Questions
14. You see 500 failed login attempts from a single IP. What do you do?
(1) Check if it’s a brute force attack, (2) Identify targeted accounts, (3) Check if any logins succeeded, (4) Block IP at firewall, (5) Alert affected users to change passwords, (6) Create SIEM rule for future detection, (7) Document in ticketing system.
15. A C-level executive reports their laptop was stolen. What’s your response?
(1) Verify the report, (2) Check if laptop had encryption (BitLocker/FileVault), (3) Trigger remote wipe if MDM is installed, (4) Force password reset for all accounts, (5) Check for suspicious activity on their accounts, (6) Enable MFA if not already, (7) Document for compliance.
