The document outlines a series of scenario-based interview questions focused on triaging security alerts within a Security Operations Center (SOC). It discusses the importance of utilizing SIEM tools, the MITRE ATT&CK framework for threat-hunting, and documentation methods to ensure efficient operations. Additionally, it emphasizes the necessity of continuous education in cybersecurity to stay informed about emerging threats and shares a personal incident response experience involving a spear-phishing attack.

2. To perform triage on SOC alerts, first prioritize them based on severity,
source credibility, and the potential impact on the organization. Analyze
the alert context within the network environment and compare it against
known attack patterns and behaviors. To differentiate false positives,
utilize historical data, adjust correlation rules in the SIEM, and apply
threat intelligence feeds to validate the alerts. This process helps reduce
false positives and focuses on genuine threats.
How can we triage alerts escalated from the SOC
and differentiate false positives from genuine
security threats?

Talking about my experience with Sentinel, ArcSight, and Splunk, I
have used them for real-time monitoring, log management, and
incident investigation. For example, I've developed custom dashboards
with Splunk to visualize threat data and created alerts for anomalous
activities based on specific thresholds. These tools have been
instrumental in my ability to quickly identify, investigate, and respond
to security incidents by providing a comprehensive view of the security
posture and enabling efficient data analysis.
Can you describe your experience with SIEM tools
like Sentinel, ArcSight, and Splunk? How have you
used these tools for monitoring and incident
response?

The MITRE ATT&CK framework is a cornerstone of threat-hunting and
incident-response strategies. It maps out adversary tactics and
techniques observed in alerts or during investigations, allowing us to
understand the attacker's objectives and anticipate their next steps.
Threat hunting references the framework to design queries and
hypotheses likely to uncover stealthy, malicious activities. During
incident response, it guides the analysis and helps develop effective
containment and remediation strategies.
How can the MITRE ATT&CK framework be
utilized in threat-hunting and incident response
activities?

Talking about MDE (Microsoft Defender for Endpoint) is used to
implement endpoint detection and response (EDR) strategies to
identify threats at the endpoint level. Carbon Black has been crucial for
real-time monitoring and preventive controls. In Azure environments, it
leveraged the security center for improved cloud security posture
management. CrowdStrike, on the other hand, provided advanced
threat-hunting capabilities. Each tool has its strengths and collectively
enhances the organization's security framework.
Explain how to use technologies like MDE
(Microsoft Defender for Endpoint), CB (Carbon
Black), Azure, and CrowdStrike in security
operations.

6. 05
Documentation is key to efficient and effective security operations. For
handover notes, ensure all critical information about ongoing incidents
or alerts is summarized for the next shift. Playbooks are developed
based on best practices and tailored to specific incident types to guide
the response process. Minutes of meetings are meticulously recorded to
capture decisions and action items. Trackers monitor the progress of
investigations, responses, and remediation efforts. This structured
approach to documentation ensures continuity and accountability within
the SOC team.
Discuss your approach to documentation,
including creating handover notes, playbooks,
minutes of meetings (MOM), and trackers.

7. 06
Cybersecurity encompasses a wide range of areas, requiring a constant
update on the latest trends and threats. Engaging with various
channels, such as news outlets dedicated to cybersecurity, online
forums, threat intelligence feeds, and professional networks, is crucial
to stay informed. Participating in webinars, training sessions, and
conferences is vital in this ongoing learning process. This commitment
to continuous education allows for anticipating emerging threats and
incorporating the latest best practices in Security Operations Center
(SOC) procedures. By keeping abreast of developments, you can
enhance monitoring and response strategies, adopting a proactive
stance that significantly strengthens your defensive capabilities rather
than a reactive one.
How do you stay informed about the latest
cybersecurity threats and trends, and how does
this knowledge impact your work in the SOC?

8. 07
In my previous organization, a notable incident involved a sophisticated
spear-phishing attack targeting senior executives. I identified the attack
by correlating unusual outbound traffic with email logs, which revealed
malicious attachments. Utilizing the incident response playbook, I
quickly isolated affected systems and began containment procedures.
We conducted a thorough investigation, identifying the attack vector
and implementing additional email security measures to prevent
recurrence. The successful incident containment with no significant data
breach highlighted the importance of rapid response and effective
communication within the SOC team.
Can you explain a complex security incident you
managed? How did you identify it and respond,
and what was the outcome?
