Question
What is Microsoft Sentinel’s primary purpose?
A. To provide Security Information and Event Management (SIEM)
B. To encrypt Azure virtual machines
C. To manage user authentication
D. To monitor compliance policies
Answer
A. To provide Security Information and Event Management (SIEM)
Explanation
Microsoft Sentinel is a cloud-native Security Information and Event Management (SIEM) solution that helps organizations collect, analyze, and respond to security threats and incidents. For more information, please refer to the “Microsoft Security Services Overview” lecture.
Microsoft Sentinel is a scalable, cloud-native solution whose primary purpose is to serve as both a Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) system. It provides a single platform for threat detection, visibility, and response across an entire organization’s digital environment.
Core Functions of Microsoft Sentinel
The SC-900 exam expects a foundational understanding of how Sentinel accomplishes its SIEM and SOAR functions.
Collect
Sentinel ingests vast amounts of data from numerous sources at cloud scale. This includes logs and alerts from Microsoft services like Microsoft 365 and Microsoft Entra ID, Azure resources, on-premises systems, and other cloud platforms. It uses data connectors to streamline this process.
Detect
After collecting data, Sentinel uses built-in analytics, machine learning, and Microsoft’s threat intelligence to identify threats and reduce alert fatigue. It correlates alerts into incidents, giving security analysts a clear picture of potential attacks.
Investigate
It provides powerful tools to investigate incidents and hunt for security threats. Analysts can visualize the scope of an attack and use built-in queries to proactively search for signs of malicious activity.
Respond
This is the SOAR capability. Sentinel allows for the automation of common security tasks and threat responses using playbooks, which are based on Azure Logic Apps. This enables a rapid response to incidents, often without manual intervention.
Analysis of Other Options
The other options describe functions performed by different Microsoft security services.
B. To encrypt Azure virtual machines: This function is handled by Azure Disk Encryption, which uses a platform’s native encryption features like BitLocker for Windows and DM-Crypt for Linux to provide volume encryption for OS and data disks.
C. To manage user authentication: This is the primary responsibility of Microsoft Entra ID (formerly Azure Active Directory). It manages user identities and controls access to applications and resources through authentication methods like passwords, MFA, and biometrics.
D. To monitor compliance policies: This is a core function of Microsoft Purview. The Microsoft Purview compliance portal provides tools to manage data governance, information protection, and regulatory compliance requirements.
