A simple way to picture Microsoft Sentinel (SIEM)
A SOC monitors threats across an organization continuously. Azure Sentinel (SIEM) does this for cloud: collecting security data, detecting threats, and enabling response.
Sentinel collects security data from across an environment, detects threats using ML, and enables investigation and response. It's Azure's security information and event management (SIEM) platform.
Connect data sources
Security data from various Azure services is connected to Sentinel.
Enable detection rules
Rules detect suspicious patterns and threats.
Investigate alerts
Teams investigate and respond to detected threats.
An organization uses Sentinel to detect unusual sign-in patterns, enabling faster response to potential compromises.
Objective 2.5 expects conceptual understanding of Sentinel as a SIEM for threat detection and response.
Sentinel detects threats across an environment.
Enables investigation and response.
Azure's SIEM platform.
Mistake
Sentinel automatically prevents all threats.
Correct
It detects and alerts; response is manual.
It's Azure's SIEM platform for detecting security threats and enabling investigation and response across cloud resources.
