SOC Operations Interview Questions — Flashcards | inGrade

Question 1

What is a Security Operations Center (SOC)?

Accepted Answer

A SOC is a centralized unit responsible for monitoring, detecting, and responding to security incidents in real-time. It integrates people, processes, and technology to protect an organization's IT infrastructure with 24/7 monitoring.

Question 2

What are the roles within a SOC?

Accepted Answer

Roles include Tier 1 SOC Analyst (alert triage), Tier 2 Incident Responder (analysis and containment), Threat Hunter (proactive threat search), SOC Manager (oversight and strategy), and Forensic Analyst.

Question 3

What is SIEM and why is it important?

Accepted Answer

SIEM (Security Information and Event Management) collects and correlates logs from multiple sources for threat detection and compliance. Popular tools include Splunk, QRadar, and Elastic Stack.

Question 4

What is SOAR and how does it enhance SOC efficiency?

Accepted Answer

SOAR (Security Orchestration, Automation, and Response) platforms automate workflows, integrate tools, and streamline incident management, reducing manual effort and response times.

Question 5

What are the six phases of incident response?

Accepted Answer

The six phases are: Preparation, Detection, Containment, Eradication, Recovery, and Lessons Learned. Frameworks like NIST 800-61 and MITRE ATT&CK guide this process.

Question 6

What is threat intelligence and why is information sharing critical?

Accepted Answer

Threat intelligence involves collecting and analyzing data about threats to predict, prevent, and respond to cyberattacks. Sharing it enhances collective defense. STIX standardizes threat data and TAXII facilitates its transmission.

Question 7

What is log management in SOC?

Accepted Answer

Log management involves collecting, storing, and analyzing log data from systems, devices, and applications to identify anomalies. Normalization converts logs to a standard format for comparison across sources.

Question 8

What are false positives and how are they handled?

Accepted Answer

False positives are benign events flagged as threats. They are reduced through better tuning of SIEM rules, machine learning models, and analyst review of alert patterns.

Question 9

What is vulnerability management?

Accepted Answer

Vulnerability management is the ongoing process of identifying, evaluating, remediating, and reporting vulnerabilities. CVSS scores guide prioritization. Tools include Nessus, Qualys, and OpenVAS.

Question 10

What is dwell time and why does it matter?

Accepted Answer

Dwell time is the duration a threat remains undetected in a system. Reducing dwell time minimizes damage. SOC effectiveness is measured by MTTD (Mean Time to Detect) and MTTR (Mean Time to Respond).
