Security Operations Center (SOC) Analysts are cybersecurity experts responsible for identifying, analyzing, and mitigating cyber attacks in an organization. The Tier 3 SOC Analysts are more experienced than Tier 1 and Tier 2 SOC Analysts in examining unknown threats. This article is curated with the interview questions for SOC Analysts L3 and helps to take a quick revision before cracking an interview.

Define
Security Information and Event Management (SIEM).
SIEM is an approach that combines the functions of Security Information Management (SIM) and Security Event Management (SEM). It helps organizations identify security threats and vulnerabilities before exploitation.
2.
What
are the various layers of the OSI model?
The OSI Model includes seven layers that develop the communication between network devices:
- L1- Physical Layer
- L2- Data-link Layer
- L3- Network Layer
- L4- Transport Layer
- L5- Session Layer
- L6- Presentation Layer
- L7- Application Layer
3.
Define
SLA.
SLA stands for Service-level Agreement, an agreement between the customer and service provider. The SLAs are categorized into three types:
- Customer-based SLA
- Multi-level SLA
- Service-based SLA
4.
Define
SOC-CMM.
The SOC- Capability Maturity Model (CMM) is an open-source model used to measure and develop the maturity and capability levels in the SOC over five domains:
- Business
- Process
- People
- Services
- Technology
SOC-CMM is a continuous maturity model that helps to measure capability and maturity based on the Design Science Research methodology.
5.
What
are the various levels of CMM?
The various levels of CMM are as follows:
- Initial
- Repeatable
- Defined
- Managed
- Optimize
6.
Explain
CSRF.
CSRF stands for Cross-Site Request Forgery, defined as an attack aiming to authenticate users to submit queries in a web application and allow hackers to exploit the system. It is also termed CSRF, Session Riding, or Sea Surf.
7.
Distinguish
between True Positive and False Positive?
The True positive is an output in which various security models are used to predict the positive class accurately known as True Positive. In contrast, a False positive is an output in which the model predicts the negative class inaccurately.
8.
What
do you understand about Threat Intelligence?
Threat Intelligence is an analysis of data using tools and techniques to develop insights on existing threats using collected, processed, and analyzed data. It mitigates data loss and implements security measures to protect the data from attacks.
9.
What
are the different types of threat intelligence?
The different types of threat intelligence are as follows:
- Operational threat intelligence
- Strategic threat intelligence
- Tactical threat intelligence
10.
